Hi
I have purchased two of the single channel 4-20ma input modules for a project which uses the ESp8266 processor. I have been able to compile the example for the ESP but when loaded it reports No Module. I can see the module at 55 with an i2c scanner but not control it
I have seen the issue raised on github about using other processors and have tried to modify the library with no success. I can load the module on an ESP32 board
Is there aproblem with using any other board except an ESp32?
Also does the module work with 3.3V instead on 5V
Thansk in advance
