A single board computer SBC is a complete computer built on a single circuit board, with microprocessors, memory, inputoutput IO and other features required of a functional computer. Single board computers were made as demonstration or development systems, for educational systems, or for use as embedded computer controllers. Many types of home computers or portable computers integrate all their functions onto a single printed circuit board. Unlike a desktop personal computer, single board computers often do not rely on expansion slots for peripheral functions or expansion.

Simple designs, such as those built by computer hobbyists, often use static RAM and low cost 8 or 1. Other types, such as blade servers, would perform similar to a server computer, only in a more compact format. A computer on module is a type of single board computer made to plug into a carrier board, baseboard, or backplane for system expansion. Historyedit. One of the first 1. MMD 1s, a prototype unit, produced by E L Instruments in 1. The dyna microMMD 1 was the worlds first true single board computer. The MMD 1 had all components on a single printed circuit board, including memory, IO, user input device, and a display. Nothing external to the single board except power was required to both program and run the MMD 1. The original design of the MMD 1 was called the dyna micro, but it was soon re branded as the MMD 1The first true single board computer see the May 1. Radio Electronics called the dyna micro was based on the Intel C8. A, and also used Intels first EPROM, the C1. A. The dyna micro was re branded by E L Instruments of Derby, CT in 1.

Book series of the time. SBCs also figured heavily in the early history of home computers, for example in the Acorn Electron and the BBC Micro. Other typical early single board computers like the KIM 1 were often shipped without enclosure, which had to be added by the owner, other examples are the Ferguson Big Board and the Nascom. As the PC market became more prevalent, fewer SBCs were being used in computers. The main components were assembled on a motherboard, and peripheral components such as serial ports, disk drive controllers, and graphics processors were located on daughterboards. The recent availability of advanced chip sets providing most of the IO features as embedded components allows motherboard manufacturers to offer motherboards with IO traditionally provided by daughterboards. Most PC motherboards now offer on board support for disk drives including IDE and SATA with RAID, graphics, Ethernet, and traditional IO such as serial and parallel ports, USB, and keyboardmouse support. Plug in cards are now more commonly high performance graphics cards really graphics co processors, high end RAID controllers, and specialized IO cards such as data acquisition and DSP Digital Signal Processor boards.

Single board computers were made possible by increasing density of integrated circuits. A single board configuration reduces a systems overall cost, by reducing the number of circuit boards required, and by eliminating connectors and bus driver circuits that would otherwise be used. By putting all the functions on one board, a smaller overall system can be obtained, for example, as in notebook computers. Connectors are a frequent source of reliability problems, so a single board system eliminates these problems. Single board computers are now commonly defined across two distinct architectures no slots and slot support. Embedded SBCs are units providing all the required IO with no provision for plug in cards. Applications are typically gaming slot machines, video poker, kiosk, and machine control automation. Embedded SBCs are much smaller than the ATX type motherboard found in PCs, and provide an IO mix more targeted to an industrial application, such as on board digital and analog IO, on board bootable flash memory eliminating the need for a disk drive, no video, etc. The term Single Board Computer now generally applies to an architecture where the single board computer is plugged into a backplane to provide for IO cards. In the case of PC1. IO boards to be stacked. Single board computers are most commonly used in industrial situations where they are used in rackmount format for process control or embedded within other devices to provide control and interfacing. Theyve been to the ocean depths ALICE deep sea probes, into outer space ARRIANE, Pegasus Rocket, and Shuttle, and to every continent on the planet. Because of the very high levels of integration, reduced component counts and reduced connector counts, SBCs are often smaller, lighter, more power efficient and more reliable than comparable multi board computers. The primary advantage of an ATX motherboard as compared to an SBC is cost. Motherboards are manufactured by the millions for the consumer and office markets allowing tremendous economies of scale. Single board computers are a market niche and are manufactured less often and at a higher cost. Motherboards and SBCs now offer similar levels of feature integration meaning that a motherboard failure in either standard will require equivalent replacement. Types, standardseditOne common variety of single board computer uses standardized computer form factors intended for use in a backplane enclosure. Some of these types are Compact. PCI, PXI, VMEbus, VXI, and PICMG. SBCs have been built around various internal processing structures including the Intel architecture, multiprocessing architectures, and lower power processing systems like RISC and SPARC. In the Intel PC world, the intelligence and interfacecontrol circuitry is placed on a plug in board that is then inserted into a passive or active backplane. The end result is similar to having a system built with a motherboard, except that the backplane determines the slot configuration. Backplanes are available with a mix of slots ISA, PCI, PCIX, PCI Express, etc., usually totaling 2. Some single board computers have connectors which allow a stack of circuit boards, each containing expansion hardware, to be assembled without a traditional backplane. Examples of stacking SBC form factors include PC1. PC1. 04 Plus, PCI 1. EPIC, and EBX these systems are commonly available for use in embedded control systems. Stack type SBCs often have memory provided on plug cards such as SIMMs and DIMMs. Hard drive circuit boards are also not counted for determining if a computer is an SBC or not for two reasons, firstly because the HDD is regarded as a single block storage unit, and secondly because the SBC may not require a hard drive at all as most can be booted from their network connections. Form factorseditSee alsoeditReferenceseditWhere can it be usedOn board diagnostics Wikipedia. On board diagnostics OBD is an automotive term referring to a vehicles self diagnostic and reporting capability. OBD systems give the vehicle owner or repair technician access to the status of the various vehicle subsystems. The amount of diagnostic information available via OBD has varied widely since its introduction in the early 1. Early versions of OBD would simply illuminate a malfunction indicator light or idiot light if a problem was detected but would not provide any information as to the nature of the problem. Modern OBD implementations use a standardized digital communications port to provide real time data in addition to a standardized series of diagnostic trouble codes, or DTCs, which allow one to rapidly identify and remedy malfunctions within the vehicle. Historyedit1. 96. Volkswagen introduces the first on board computer system with scanning capability, in their fuel injected. Type 3 models. 1. Zoster Free Download there. Datsun 2. 80. Z On board computers begin appearing on consumer vehicles, largely motivated by their need for real time tuning of fuel injection systems. Simple OBD implementations appear, though there is no standardization in what is monitored or how it is reported. General Motors implements a proprietary interface and protocol for testing of the Engine Control Module ECM on the vehicle assembly line. The assembly line diagnostic link ALDL protocol broadcasts at 1. Implemented on California vehicles for the 1. United States in 1. Most owners can read DTCs Diagnostic Trouble Codes by commanding the ECM Engine Control Module to flash the CEL Check Engine Lamp or MIL Malfunction Indicator Lamp on and off. A PC based Software package called Win. ALDL will listen to the CLCC Closed Loop Carburetor Control and early CLC EFI datastreams over a fairly easy to construct interface cable that converts the 1. TTL serial data being transmitted by the ECM to RS2. USB2 serial data but there is not much information transmitted by these early ECMs. An upgraded version of the ALDL protocol appears which communicates at 8. UART signaling. This protocol is defined in GM XDE 5. B. 1. 98. 8 The Society of Automotive Engineers SAE recommends a standardized diagnostic connector and set of diagnostic test signals. The California Air Resources Board CARB requires that all new vehicles sold in California in 1. OBD capability. These requirements are generally referred to as OBD I, though this name is not applied until the introduction of OBD II. The data link connector and its position are not standardized, nor is the data protocol. Motivated by a desire for a statewide emissions testing program, the CARB issues the OBD II specification and mandates that it be adopted for all cars sold in California starting in model year 1. CCR Title 1. 3 Section 1. CFR Part 8. 6 Section 8. The DTCs and connector suggested by the SAE are incorporated into this specification. The OBD II specification is made mandatory for all cars manufactured in the United States to be sold in the United States. The European Union makes EOBD mandatory for all gasoline petrol vehicles sold in the European Union, starting in MY2. European emission standards Directive 9. EC4. 2. 00. 3 The European Union makes EOBD mandatory for all diesel cars sold in the European Union. All cars sold in the United States are required to use the ISO 1.

Standard interfaceseditGMs ALDL Assembly Line Diagnostic Link is a General Motors proprietary onboard diagnostic interface that started with the late 1. CLCC Closed Loop Carburetor Control and early GM EFI systems. Theres an appearance of standardization because the diagnostic jack didnt change over the years ALDL was utilized by GM. GM North America used a proprietary 1. Metripack 2. 80 diagnostic jack. GM Australia Holden used a 6 position Metripack 2. The GM Europe Opel and Vauxall used a 1. Metripack 2. 80 diagnostic jack. ALDL was not a standard. It was actually extremely fragmented. The information exchange changed with each powertrain control module aka PCM, ECM, ECU. A PCM integrates transmission and engine control on one Processing unit. ECMECU are engine control only with a separate TCM Transmission Control Module if needed. While ALDL is the closest thing to standard onboard diagnostics prior to 1. Isuzu Hombre Service Manual. ALDL was not a standard. ALDL was even fragmented within GM brands, models, and model years. Trim levels in the same model year, division, and nameplate can use different communications. Different versions presented differences in diagnostic jack pin outs, data protocols, and data rates this is the reason for the Mask files needed for aftermarket software communication. Earlier versions used 1. PCM or ECMTCM. 1. ALDL on 1. 99. 1 and later California emissions GM vehicles met the 1. California OBD I communication standard. This does not mean that ALDL is OBD I. OBD I was an early 1. California only mandate, not a United States federal mandate. It was not used on non California emissions vehicles. Some Asian, European, and North American diagnostic ports are sometimes incorrectly referred to as ALDL. A small number of vehicles manufactured before 1. GM Delphi Electronics engine and powertrain controllers however, these used a modified ALDL communication protocol. Most did not and there was not a homogeneous name for these other proprietary diagnostic protocols and interface ports. Ford EEC, Toyota DLC, Chrysler, Nissan, Volkswagen, and others used their own onboard Diagnostics protocols and connectors, and are also not OBD I compliant outside California. Multiplex OBD or M OBD is an OBD variant protocol used by Toyota, prior to OBD II compliance. Toyotas DLC3 Data Link Connector 3 is the standard 1. OBD II connector, but a proprietary cable and software is required as generic OBD II cables and software will not interface with it. The bus line is SIL Pin 71. A 1. 99. 1 and later California standard. It is not a USA Federal standard. The regulatory intent of OBD I was to encourage auto manufacturers to design reliable emission control systems that remain effective for the vehicles useful life. The Diagnostic Trouble Codes DTCs of OBD I vehicles can usually be found without an expensive scan tool. Each manufacturer used their own diagnostic link connector DLC, DLC location, DTC definitions, and procedure to read the DTCs from the vehicle. DTCs from OBD I cars are often read through the blinking patterns of the Check Engine Light CEL or Service Engine Soon SES light. By connecting certain pins of the diagnostic connector, the Check Engine light will blink out a two digit number that corresponds to a specific error condition. The DTCs of some OBD I cars are interpreted in different ways, however. Cadillac gasoline fuel injected vehicles are equipped with actual on board diagnostics, providing trouble codes, actuator tests and sensor data through the new digital Electronic Climate Control display. Holding down Off and Warmer for several seconds activates the diagnostic mode without the need for an external scan tool.
