This is a template based on the Arduino Uno R3. It has all the nets and connections of the R3 except the SPI bus connector. It allows the user to create an Arduino-Uno form factor board, either as a shield or as a baseboard with their own microcontroller device on it.
This design uses the defaul Altium 2-layer PCB stack and design rules. You must modify them to suit your own design.
