The tHAT module offers additional 4 outputs in the open collector standard, driven by PWM outputs, for controlling relays. The board also has an RS485 converter for Modbus bus support. There are also outputs OUT1-OUT4 and supply voltage, analog inputs INPA5 and INPA6, and 3.3 V voltage for powering sensors.
The overlay is available in two versions:
tHAT_TR with relay outputs in the form of separable terminals.
tHAT_IDC10 with IDC10 connectors for connecting a relay board.
To control outputs 6-9 you have to enable Mode ON/OFF for pwm outputs like on image below.
