tHAT - 4 relay outputs and Modbus converter

For Lan Controller v3.7

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 (only for Lan Controller HW 3.7). 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:

  • 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.
