Eagle based PCB layout file for an Arduino compatible microcontroller optimized to run an electronic dividing head using a stepper motor using Chuck Fellow's electronic divider head sketch.
Also the schematic file for this controller board, and the layout and schematic for the 5 button lighted keypad breakout board designed for use with the controller.
The PCB layout features headers for mounting Pololu's A4988 stepper motor driver carrier, a separate lighted keypad header, and a header for either a 20x4 or 16x2 LCD display, and headers for an external LED power indicator and a 12V cooling fan attachment. The board input voltage is soldered to a panel mounted dc power jack & power switch.
The board is designed to fit within a compact enclosure to protect the controller from the shop environment.
NOTE: right click the file name and select "save as" to save the code properly.
