GPIO Interfaces
ROCK 3C provides a 40pin GPIO socket, which is compatible with most sensor applications on the market.
caution
Tips: The actual compatibility is subject to usage.
caution
Pin 3 and Pin 5 have additional pull-up to power downstream I2C devices, as such when used as GPIO they may not work correctly.
