From the project

⌨️ Sudi V2 is custom wireless split keyboard

Sudi V2 is custom wireless split keyboard based on NRF52832 Nordic Semiconductor Microcontroller series, each side consist 18 keys 36 in totals, use MCP23017 I2C I/O expansion to scan one side of keyboard, and use wire to trasfer data to NRF52. Built in SWD debug port, with Serial Logger based on CH340G. Sudi Have interactive RGB LED and OLED 0.91 inch for graphic display. Planned to create 3D print enclosure.
