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.
