Multiuse PCB3: A simple PCB with many uses


This is a design based on the Atmel Atmega8a meant to be used with the V-USB driver. Most of the MCU inputs/outputs pins are exposed.

  • The footprint used to expose signals is compatible with many terminal blocks and with quickconnect tabs. Otherwise, it is easy to solder wires directly to the board.
  • One optically isolated input can be populated.
  • On-board USB Type B standard connector.
  • One on-boad LED for feedback controlled by the microcontroller.
  • Components required for V-USB operation are present.
  • On-boad activity LED.
