# mnhTTn

mnhTTn is a 36 key column-staggered split keyboard using Cherry MX ULP switches.

Designed to be as flat and lightweight as possible.

## Features

* [Cherry MX ULP Switches](https://www.cherry.de/mx-ulp-click)

* Bluetooth [via SEEED XIAO BLE](https://www.seeedstudio.com/Seeed-XIAO-BLE-nRF52840-p-5201.html)

* Only 7.2mm height

## Layout

## PCB

[Here](/board/) you can find the KiCad fies for the PCB.

To archive minimal height, you can order the PCB as low as 0.6mm thick.

But this requires additional attention while soldering on the swithches to prevent the board from warping caused by thermal expansion.

## Keycaps

There are no keycaps available off the shelve but have been manifactured using MJF in nylon.

The models are availabe [here](/keycaps/).

## Build Guide

The build guide can be found [here](/docs/buildguide.md).

## Firmware

My [ZMK config](https://github.com/fooker/mnhttn-zmk) for the mnhTTn.

## Other Versions

There are other versions, derivats and spin-offs of this keyboard:

- **[mnhTTn48](https://github.com/venc0r/mnhttn)**: A 5*4+3+1 Keys versions with an additional top row and and extra key right above the diode array

If you have build or want to build something based on the mnhTTn keyboard or know about somebody that has created something with it, feel free to reach out and I will happly extend this list and provide support.

## Credits and inspirationt

The idea to creat such a keyboard emerged from the wonderfull [Click! Clack! Hack!](https://www.clickclackhack.de/) community.

The layout of the board is inspired by [TOTEM](https://github.com/GEIGEIGEIST/TOTEM).

And I got a lot of help and feedback from all around the mechanical keyboard community :heart:.
