3.3 V rail required when connecting the HAT/Bonnet off-Pi via jumpers, alongside GND, SDA and SCL.
Common ground required when connecting the HAT/Bonnet off-Pi via jumpers and shared return for motor/control power.
Polarity-protected 2-pin terminal block for external motor power; Adafruit specifies external 5-12 VDC power on the Bonnet product page and 4.5-13.5 VDC motor drive range in the shared guide.
Motor terminal block output channel for one DC motor winding/output pair, driven by the onboard TB6612 motor driver.
Motor terminal block output channel for one DC motor winding/output pair, or one half of a stepper motor connection.
Motor terminal block output channel for one DC motor winding/output pair, or one half of a stepper motor connection.
Motor terminal block output channel for one DC motor winding/output pair, driven by the onboard TB6612 motor driver.
STEMMA QT connector on the I2C lines for plug-and-play usage, as stated on the Adafruit product page.
