Minimalist Unicorn Controller
thingiverse
This is a work in progress because I have yet to successfully program the ATMega 168. This is the RepRap/MakerBot Extruder Controller, but without all the extruder-controlling bits. I would love to have a dedicated Unicorn Plotter controller board, but don't want to shell out $45 for one. The schematic just contains all the necessary parts for an Arduino to be controlled and powered over RS485 with two digital I/O ports. The board file is experimental! It should work, but there's no guarantee. By the way, this board costs around $20 (including components) to make, but only if it's priced in groups of 10. Instructions Convert to Gerber files to be used by your PCB creation service. Get it produced. Get the parts and solder everything up. Flash the firmware to the board. Connect to Unicorn Servo. Enjoy your Unicorn!
