I2C
I2C is a multi-master, multi-slave synchronous serial communication bus that uses two signal lines (SDA and SCL). It is commonly used to connect low-speed peripherals.

The modular keyboard project uses a 1U PCB for each key with a CH32V003 RISC-V microcontroller, while the main board uses an STM32WB55RGV6 for Bluetooth and USB; keys are powered via pogo pins and communicate over I2C; each key costs about $8 to $10, and the firmware is still in development.
In the embedded field, multi-board assembly usually means using inter-board buses (such as I2C, SPI, or dedicated backplane connectors) to let multiple controllers work together, each responsible for different peripherals or tasks.
The author concludes that when writing standard interface modules such as UART, SPI, I2C, PWM, and I2S, the AI can write them correctly about 90% of the time.
