WIFI, Ethernet, and Bluetooth connectivity
Digital Input x 2
- IN1 — GPIO36
- IN2 — GPIO39
- If INx short connect to GND, the GPIO will detect LOW signal;
Digital Out (Relay) x 2
- Relay 01 — GPIO2
- Relay 02 — GPI015
- Rating: 10A/277VAC, 12A/125VAC
- Relay parameters: JQC-3FF-5VDC-1ZS
RS485 Port
- A — GPIO35
- B — GPIO32
Temperature detection x 2 (1 wire) using DS18B20
- TEM1 — GPIO33
- TEM2 — GPIO14
- By simply connecting 3V3, GND, and either T1 or T2, temperature detection can be achieved.
Buzzer
- GPIO12
- used for system startup prompts, connection success prompts, abnormal alarm, development and debugging assistance, and operation confirmation.
IIC expansion interface * 2
- SDA — GPIO4, SCL — GPIO16
- Port 1 (12V): the above pins, can be connected to DO8 to achieve the interface expansion of the relay output.
- Port 2 (5V): same pins, using this port the EA2 and SHTX sensors can be connected to achieve temperature and humidity detection.
Supports SIM7600 4G module and SIM800L 2G module
- GSM_RX - GPIO13, GSM_TX - GPIO5
- SIM7600 4G_Module: the above pins, used for remote communication and remote control
- SIM800L 2G_Module: same pins, used for remote communication, remote control, SMS notifications and simple IoT applications.
Ethernet Port
- used for high speed and stable network connection, remote access and control, and interconnection with other network devices.

Connectivity

Digital input connection

The following is the wiring method, connected to a wired door sensor with NO and NC states and a 2-gang self-reset Switch. IN1 should be connected to Door sensor’s NO line. IN2 should be connected to Door sensor’s NC line.
