- **Board**: We used a non-standard CYD variant; [1005008564907457] from Aliexpress also known as E32R28T, mostly for the price and USB-C connector. The peripheral connectors are placed a little differently from the commonly documented ESP32-2432S028R. The pin configuration in this project is specific to this board and may not work on other CYD revisions without changes to the GPIO assignments. - **Board**: We used a non-standard CYD variant; [1005008564907457] from Aliexpress also known as E32R28T, mostly for the price and USB-C connector.

peripheral headers (GPIO23/19) over I2C. 3.3V and GND are available on the other header, so a custom cable is needed. peripheral headers (GPIO23/19) over I2C. 3.3V and GND are available on the other header, so a custom cable is needed.
See `include/config.h` for pin assignments. The keyboard uses pins IO19 and IO23 for I2C, which are also wired to the SD card SPI pins. So no SD card support regrettably.
