This is a BIGTREETECH Relay V1.2 Automatic Shutdown Module. BIGTREETECH Relay V1.2 is an upgrade of the original (BIGTREETECH V1.0). After upgrading, a small MCU was added on the module to make the module more controllable and stable. Besides , we have also increased short circuit detection circuit. After connecting the 5V and GND on the motherboard to the module, if there is a 5V short circuit, the module will immediately power off to prevent damage on the motherboard and the risk of fire caused by short circuit. BIGTREETECH Relay V1.2 Automatic Shutdown Module will automatically cut off the power after printing, which is very energy saving and environmental friendly. It also reduces the risk that the printer will remain powered up after printing.

Features:

  1. Higher controllability and stability
  2. Powerful detection function
  3. Super save electricity
  4. Energy saving and environmental friendly

Package Includes:

1 x BIGTREETECH Relay V1.2 Automatic Shutdown Module

1 x Connector cable

Setup Guide

1
Identify the pins
Locate VCC (power), GND (ground), and data pins (SDA/SCL for I2C, MOSI/MISO for SPI, or TX/RX for UART). Refer to the pinout diagram on the product page.
2
Wire to your microcontroller
Connect VCC to 3.3V or 5V (check the module spec), GND to GND, and data pins to the appropriate GPIO pins on your Arduino or Raspberry Pi.
3
Install libraries
In Arduino IDE, go to Sketch → Include Library → Manage Libraries and search for the sensor library. Install the recommended version.
4
Upload example sketch
Open File → Examples → [library name] → Basic Example. Upload to your board and open Serial Monitor to view output.
5
Calibrate if needed
Some sensors (temperature, humidity, distance) may need a short warm-up period or calibration. Run the calibration sketch if provided.
