Ⅰ.Product Introduction
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.
The 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.
