tHAT - 4 relay outputs and Modbus converter

For Lan Controller HW 3.7, 3.8

The tHAT overlay offers an additional 4 relay outputs in open collector standard, which are controlled from the PWM outputs. The board also has a RS485 converter to support Modbus. OUT1-4 relay outputs and supply voltage, analog inputs INPA1 and INPA2 as well as voltage 3.3V to supply sensors are also led out.


The overlay is available in two versions:

To control outputs 6-9 you have to enable Mode ON/OFF for pwm outputs like on image below.
