Zireael keyboard

Dao Shield Zireael is an ergonomic wireless split keyboard with a design bias. Keyboard for Kailh Choc switches based on MINEW MS88SF2 BLE module.

The keyboard is based on Dao Chok BLE. The locations of components on the board have been changed, space for the battery has been added, and the thumb cluster has also been changed.

Inspiration for the keyboard was taken from these keyboards:

Questions

How big is the Dao choc ble right PCB?

It measures 132 × 90.7 mm and has 2 copper layers, 1.6 mm thick.

What parts does the Dao choc ble right use?

79 parts, built around the MS88SF2, MCP73831, USBLC6-2SC6 and 1N4148WS. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.

Where can I download the Dao choc ble right KiCad files?

From the Mposiblee/Zireael repository on GitHub, at the commit this page was made from: the board is kikad/dao-choc-ble-pcb-right/dao-choc-ble-right.kicad_pcb and its schematic kikad/dao-choc-ble-pcb-left/dao-choc-ble-left.kicad_sch. PCBKit opens the board in the browser, with nothing to install.

Can I use the Dao choc ble right design in my own project?

Its repository publishes it under the CERN-OHL-P-2.0 licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
