- v0.3 STM32 PCBs ordered 05/01/21
- Assemble Arisutea PCB once received 05/21/21
- Assemble Acrylic Case to Arisutea STM32 design
- Edit QMK firmware for Arisutea STM32 design
Fairly confident that this will be the first actual version (v0.3 because...reasons...) of the STM32 version of the Arisutea board. See the notes below on the modification for this version. You will need KiCad 5.99 to view/edit these files.
アリステア PCB designed using KiCad. The layout was originally created by FateNozomi, inspired by Lyn's EM7 and TGR Alice with some modification. The layout was then modified by CorruptedJef and robotictomato to add USB-C, ESD and to shift/add some keys. This inspired me to modify the layout further by adding an STM32 and the ability to swap your switches out whenever you want and to make some keys a little more permenant. I have designed many boards in the past but never a keyboard so this is my first crack at it and I figured why not go all out? If you notice any issue please open an issue and we can discuss!
Since the layout has been modified yet again I decided to give the project a new name, Arisutea, which translates to Alistair. Obviously keeping the theme running here.
Key modifications to the PCB:
- STM32F072 MCU
- STM32F102 can be used but a crystal will need to be placed at Y1 (v0.4 - not tested)
- Added in Kailh Hotswap sockets.
- Addition of full backspace position, connected to switch 59 (row 0, column 13).
- Removed switch 63 and repositioned switch 59 to add full backspace position.
- USB-C ESD rework.
- Added LED indicators for CAPS and NUM lock as well as layer.
- Updated JSON layout file for this particular keyboard.
- Original mounting holes have been returned to their rightful place. The idea of widening them was good at the time for FR4 plates, but not very practical. I am redesigning the case to allow for brass inserts and standoffs to be installed so the PCB will be nice and snug. More on that later. FR4 plates still will work but you will have to drill the holes out manually. If you take this route....go forth cautiously adventurer.
