VOID16

A 4x4 handwired macropad

The VOID16 is a 3d printed, handwired, 4x4 macropad running QMK Firmware on a Pro Micro controller.

I suggest printing the case using a 0.4 mm nozzle, supports are not needed for any of the parts.

You might want/need to use small dabs of hot glue to secure the switches in the plate depending on how well calibrated your printer is (if you're generous with it, it will add to the weight of the keyboard and it might change the feel of it).

Dont overtighten the screws as the threads might get stripped.

Handwiring guide

I've also put together a pretty visual handwiring guide for the VOID9, that you can browse over here.

QMK Vial Fork

A QMK Vial fork can be found here.

Most features are disabled in order for the firmware to fit on the atmega32u4 present on the Pro Micro controllers, but if you want to tinker around with different features or if you're using a different MCU you can enable/disable them to suit your own needs by editing the rules.mk file in the vial keymap folder.

The web version of Vial is available at vial.rocks; it runs in supported browsers (Chrome, Edge and Opera) without requiring an installation.

QMK Fork

A fork containing the QMK config files can be found here. Edit them to suit your own needs and build the firmware following the QMK docs.

If you plan on using the VIA configurator dont forget to download the json definitions file linked in this repository.
