Amicus is a PIC microcontroller development system inspired by the popular Arduino board and it is using a PIC mcu instead of an ATMEL. The Amicus hardware is open meaning schematic and design files are free to download. Also Amicus software and IDE (integrated development environment) is free of charge. Check details on the link below.
