    Buyed one for installing custom firmware to open a garage door. Had to reverse eng. to find pinouts since there's no schematics. Found : GPIO4/19 = Relay (node MCU arduino pin name : D2) GPIO5/20 = input (node MCU arduino pin name : D1) 2 leds seems to be connected, one on output (activated a the same time of relay) and one on optocoupled input. I did not played with the input, but it seems it have to be powered with a 5V to activate. 2 connectors (2 pins, and 3 pins) have to be soldered to

    The card arrives with power problem: the positive pcb stop near coil L1 ! In order to fix this problem need to make a little jump wire (brow cable) from fuse to coil pad. After this the board work, but only in access point mode. Someone has changed the wifi permission to use in existing network?
