To enable the user to connect external hardware, Thingy is equipped with a set of
connector footprints and transistors to drive higher currents.
N-MOS transistors
For more flexibility, Thingy is equipped with four N-MOS transistors that can be used to drive small DC motors or LEDs. The drain and source of the transistors are available on external connectors and the gate is connected directly to the nRF52832.
Connectors
Extra GPIOs can be found on connector P4. In addition to P4, some of the GPIOs are available on connectors P5-P8.
