Post History

I support this idea and think that it might fit the Papers category, although it should be allowed to have multiple users maintain and moderate it. It should be a brief glossary for a quick look-up of technical terms.

Perhaps use a single word as "defining category", as seen in a dictionary and can be used for disambiguation. 

It could be in the following format, syntax:


- **[abbreviation] - [Meaning]** (_category_). Simple explanatory text here, preferably one sentence. May use other technical terms used in electrical engineering without further explanation of those term.

Example:

- **LQFP - Low Quad Flat Package** (_package_). A low profile version of a quad flat package, see QFP.
- **MCU - Microcontroller Unit** (_integrated circuit_). An integrated circuit containing a CPU, RAM memory, ROM memory and programmable hardware, so-called hardware peripherals.
- **PCB - Printed Circuit Board** (_component_).  A board made typically made out of a fiberglass reinforced epoxy, which has traces on at least one side and is used to mount electronic components.
- **PWM - Pulse Width Modulation** (_signal_). A square-wave signal consisting of a period and a duty cycle.
- **QFP - Quad Flat Package** (_package_). A square-shaped, standardized package for SMD components using a fixed number of gull wing leads per side. They are specified by the total number of pins such as for example LQFP48.
- **SMD - Surface-Mount Device** (_component_). A method and type of component reflow-soldered at one side of a PCB without the need to drill holes through the board.
- **SPI - Serial Peripheral Interface** (_bus_). A common, synchronous serial bus used for high speed, short distance communication, typically using up to 4 signals in full duplex.
