6An atmega32u4 based split 34 keys column staggered keyboard named and decorated after the rustlang mascott. All PCB files and some thoughts on the design are available on the [project's github page](https://github.com/pierrechevalier83/ferris)
7
8* Keyboard Maintainer: [Pierre Chevalier](https://github.com/pierrechevalier83)
9* Hardware Supported:
10 * Ferris 0.1: atmega32u4 chip. Comes in 4 variants: base, low, high and compact
11* Hardware Availability: Pierre Chevalier has been selling keyboard kits (see the #ferris channel in the 40% discord chat). Wider availability is on the horizon.
12
13Make examples for this keyboard (after setting up your build environment):
14
15 make ferris/0_1:default
16
17See the [build environment setup](https://docs.qmk.fm/#/getting_started_build_tools) and the [make instructions](https://docs.qmk.fm/#/getting_started_make_guide) for more information. Brand new to QMK? Start with our [Complete Newbs Guide](https://docs.qmk.fm/#/newbs).

1# A test keymap for the Ferris keyboard
2
3This keymap is not intended to be used to use the Ferris as a usable keyboard, but rather it is meant to be a very simple keymap used to test the hardware works properly. It can also be used to test firmware being written for new versions with a minimum amount of complexity coming from the keymap itself.
4
5The keymap is composed of a single qwerty layer with a unique digit bound to each non-alpha key.
