![ErgoTravel](https://i.imgur.com/H9t6Q7b.png)


A split ergo 4x6 keyboard with 2 or 3 thumb keys and extra inner macro keys designed by Pierre Constantineau. [More info on the GitHub Repo](https://github.com/jpconstantineau/ErgoTravel).

**Status** The ErgoTravel is currently being beta-tested.  

Keyboard Maintainer: [/u/jpconstantineau](https://github.com/jpconstantineau)  

Hardware Supported: Pro Micro (ATmega32U4) 

Hardware Availability: [Group Buys](https://keyboards.jpconstantineau.com/) or order your own [yourself](https://github.com/jpconstantineau/ErgoTravel/blob/master/OrderingInstructions.md)


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

    make ergotravel/rev1:default

Example of flashing this keyboard:

    make ergotravel/rev1:default:avrdude

See [build environment setup](https://docs.qmk.fm/build_environment_setup.html) then the [make instructions](https://docs.qmk.fm/make_instructions.html) for more information.

A build guide for this keyboard can be found here: [Build Guide](https://github.com/jpconstantineau)
