We assembled a benchmark of electronic component pinouts, PINS100, containing 100 common parts frequently used in circuits found on high-traffic electronic tutorial websites such as the ARDUINO PROJECT HUB and AUTODESK TINKERCAD CIRCUITS. Components range from 2 pins to 40 pins, and span a large assortment of part categories including passives (e.g. resistors/capacitors), input (e.g. switches), output (e.g. LEDs, motors, relays), sensors, integrated circuits, power regulators, logic (e.g. 7400- SERIES AND and OR gates), and microcontrollers (e.g ARDUINO, RASPBERRY PI ).
