More info

It is maximally extended Lan Controller 3.5 HW3.8 version.

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.

Basic overlay features:

  • 8 open collector outputs to control the relays, IDC10 connector, compatible with the relay board, OUT1-4, PWM0-3 outputs
  • RS485 module for communication in the Modbus standard, A+ and B- outputs
  • GSM SIM800C module with GPRS support
  • SIM card connector in the nano SIM standard
  • antenna socket on the board and attachable GSM antenna
  • battery of supercapacitors to maintain the operation of the module and controller, to send notifications about power failure

The GSM overlay enables:

  • Controlling outputs via SMS (on/off/reset).
  • Sending SMS as an action in Events.
  • Sending HTTP requests (e.g. cyclical sending of readings) over the mobile network.
  • Sending MQTT data (e.g. sensor readings, controlling outputs) over the mobile network.

NOTICE: The GSM module uses a serial port, therefore it is no longer available for connecting other devices or sensors.
