What is the pinouts for this module? | Electronics Forum ...

Jun 29, 2019· This JDY-62 module has a nearly same pinout as the MH-M18, which I decide to use in a project. The MH-M18 support 4 buttons, while JDY-62's pin 1 has no function. Another difference is the undocumented power pin in M18 is connected to the tail of the diode, so I guess battery can be directly applied at this pin whithout short the diode.
