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 closed-loop drive is to feedback the rotation angle of the stepping motor to the control panel, compare the distance that needs to be rotated with the distance of the actual rotation, calculate the error value, and then compensate, so as to prevent the problem of multi-step and lost step. The closed-loop drive can completely overcome the lost step of the open-loop stepping motor, and can also significantly improve the performance of the motor at high speed
