tHAT2 + GSM overlay
For Lan Controller HW 3.7, 3.8
Version of the tHAT2 overlay extended with a GSM module, currently available in the IDC10 version with IDC10 connectors for connecting the relay boards.
The tHAT2 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.
Basic 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 LC
- 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.
The GSM module uses a serial port, therefore the port is no longer available for connecting other devices or sensors.
