BigTreeTech relay module V1.2
This module automatically interrupts the power after printing, this is very energy-saving and environmentally friendly.
It also reduces the risk of the printer being left on after printing.
BIGTREETECH Relay V1.2 is an upgrade of the original (BIGTREETECH V1.0).
A small MCU was added to make the module more controllable and stable. In addition, the short-circuit detection on the 5V line has been integrated.
The module switches itself off immediately to avoid damage to the main board and the risk of fire due to short circuits.
AC input voltage 85V - 265V
Logic voltage: DC 3.3V - 5V
Supports resuming printing after the printer has been switched off
Detection of power failures
Detection of short circuits
