Topre version of the iconic is0 board.
This project is a continuation of my development of open source EC boards.
Below is the KLE of the supported layout:
- Layout size: ISO enter
- Compatible switches: EC switches (Topre and NIZ)
- Microcontroller: Atmega32u4
- Connector: USB Type C
- Firmware compatibility: QMK (with VIA/VIAL support)
- Protection hardware:
- Fused
- ESD protection
**Addition: an empty spot for a 3.5x3.5mm SK series LED has been added to the back of the PCB, in case you want to manually add a bit of lighting.
Topre housing compatible plate:
MX plate mounted stabilizer compatible plate:
Atmel MCU based firmware is validated, you can find the precompiled .hex (Vial compatible) and .json file for VIA in the firmware folder.
STM32 based MCU version is in development.
Given the difference in height and mounting system some modifications are needed.
At the time of ordering the PCBs be sure to use the following specs:
- 1.2mm thickness for the main PCB
- 0.6mm for the plates
In order to have the correct fit place in the marked spots adhesive tape, specifically:
- 2pcs, 0.4mm thick on the main PCB
- 4pcs, 0.1mm thick on the plates
These will ensure that all the tollerances are met and a secure fit is achieved.
