mechmini

A compact ortholinear/staggered keyboard.

Keyboard Maintainer: QMK Community
Hardware Supported: mechmini PCB
Hardware Availability: https://mechkeys.ca/collections/keyboards/products/mechmini-2-0-pcb

Make example for this keyboard (after setting up your build environment):

make mechmini:default

See build environment setup then the make instructions for more information.

Mechmini Notes

Note that this is a complete replacement for the firmware, so you won't be using Bootmapper Client to change any keyboard settings, since not all the USB report options are supported.

Installing

First, install the requirements. These commands are for OSX, but all you need is the AVR toolchain and bootloadHID for flashing:

$ brew cask install crosspack-avr
$ brew install --HEAD https://raw.githubusercontent.com/robertgzr/homebrew-tap/master/bootloadhid.rb

In order to use the ./program script, which can reboot the board into the bootloader, you'll need Python 2 with PyUSB installed:

$ pip install pyusb

Then, with the keyboard plugged in, simply run this command from the qmk_firmware directory:

$ make mechmini:program

If you prefer, you can just build it and flash the firmware directly with bootloadHID if you boot the board while holding down L_Ctrl to keep it in the bootloader:

$ make mechmini
$ bootloadHID -r mechmini_default.hex

Troubleshooting

From my experience, it's really hard to brick these boards. But these tricks have been useful when it got stuck in a weird scenario.

1. Try plugging the board in while pressing L_Ctrl. This will force it to boot only the bootloader without loading the firmware. Once this is done, just reflash the board with the original firmware.
2. Sometimes USB hubs can act weird, so try connecting the board directly to your computer or plugging/unplugging the USB hub.
