Proto Shield PCB Rev3

Proto Shield PCB (no connectors, nor other elements), pin compatible with Arduino UNO R3 (IOREF, SDA/SCL)

With this PCB You can build more durable extension (compared to breadboards)

We suggest headers to get access to all Arduino ports and female 3 pin headers and 2x3 pin for connector to ICSP. This second product is especially useful for Leonardo-like boards, where some signals are only on ICSP header.
