[Solved] Help required with a JDY-40 (EY-40) Wireless Transceiver Module.

Thank you Scott.

I will experiment .

That is the issue with this modules.

Luck of documentation.

Thank you very much.

Ion

I have one more question which is capital for me.

I read that we can program each pin as input or output.

Did anybody did it ?

I want pins 1,2,3 and 4 to be input and pins 5,6,7 and 8 to be output.

Can be done ?

Does anybody has the magic formula to follow , with an example ?

And talking about the outputs, how much current can i draw from and output. I want to connect some relays .

The documentation is really limited and i have to rely on others experiments.

Thank you for help.

I don't think it can be used as a general IO type controller unless you change the built-in firmware. Looks like you can have one in a "remote control transmit mode" (GPIO all inputs) and another as "Remote receive mode" (GPIO all outputs)  I would assume it would not drive a relay directly and would need a transistor or optoisolator in front of the IO line to drive it, and also a flyback diode across the relay.   I think when the module is in this mode, it can't be used as a data transceiver for a microcontroller. 

Thank you
