ah very interesting. Thank You for the correction! I quickly saw what looked like pci and some GPIO options.

- SV_BubbleTime 5y agoLooks like you communicate through that header over I2C, USB, or “serial”… which I am not sure if they mean SPI or UART/USART (or yes).
- rozzie 5y agoAll of USB, I2C, low power UART (9600 fixed), and high speed USART. They all equivalently are JSON request/response ports. I2c uses a simple serial-over-I2C protocol. Most customers use the I2C or low power UART interfaces because the device only uses ~8uA when listening on those ports. (Our internal MCU can listen on those ports while in STOP2 mode.)
