Hi Dave,

My again.

Arduino (Atmel) and Amicus18 (PIC) are different platforms. The board and shields are outline the same. Not electrical.

You can update a Amicus18 board (or clone like the Ami18 board) to a PIC18F25K22 The Amicus IDE and free Proton Compiler (V 1.0.1.6) support the PIC18F25K20 (3V3) and the PIC18F25K22 (5-volt)

Regards,
Gevo
