4x4 Macro Keyboard

thingiverse

A simple macropad using a 3rd party pro-micro. I've included my firmware that you can flash to your microcontroller using qmk toolbox. There's a keymap included on this page showing what macros I have assigned. Follow these guides from QMK for wiring diagrams and tips! https://beta.docs.qmk.fm/using-qmk/guides/keyboard-building/hand_wire Frame, insulator, and base were all printed at 0.28 layer height. The keys were printed at 0.12 mm. Build Instructions: - snap all switches into the frame - solder all columns together with wire - solder all rows together with diodes between each switch - place the insulator over the wire matrix - solder a lead from the end of each row/column to a pin on the microcontroller - flash firmware and test - tape the pro micro to the slot in the base - screw it together and get typing! Components: 3rd party Arduino pro micro x 1 cherry mx style switches x 16 diodes x 16 M3 screws x 4 wires double sided tape patience...
