Thanks for the reply! I was looking also on the other library regarding the E22 module that is very interesting. I think the pin configuration should be the same. Am I right?
For the AUX pin I can use pin 15 as the shield with a pull up resistor, but for M1 and M0 I can use pin 27 and pin 25 if I read correctly, they should be fine.
In final production phase I will probably just connect M0 and M1 directly to 3.3V or GND depending on the use. I was wondering: I know that the module works better with higher voltage than 3.3V, I’m powering up everything with an 18650 battery, can I power also the E22 module with the battery in order to have higher voltage than 3.3V, instead of power the E22 with the 3.3V from the ESP?
