#KeyBored, KeyBored in DFU, KeyBored in BLE
Left-side Knob is a must for me, cuz i think it is totally not efficient when I use the knob while only left hand is used. (This project is still in development and may contain bugs and defects)
Self-designed keyboard and firmware, using STM32F105RCT6 or L475RCT6 as the main MCU.
- 1000Hz scan rate (L475), 250Hz (F105)
- left-side knob design
- WS2812 addressable LED
This keyboard uses seperate design to minimise my development cost.
| v0 | v1 |
|---|---|
| using F105RCT6, no BLE | using L475RCT6, BLE supported by ESP32-c3 |
The USB function development is done, thjis KeyBored is fully functional in USB connection.
- BLE using ESP32C3FH4; ESP firmware is still under development, fimware upgrade feature will be available in the future.
You can upgrade the main MCU firmware through DFU by using STM32CubeProg. (I'm still working on the L475, cuz it doesn't work with F105's code).
