I used a esp12 mini. It’s same size as the motor shield. I hot glue those 2 together and it’s only a little unit which fits in small spaces

Update: I now have a working MTC4PF. Unfortunately I have no idea what I did to make it work so I didn’t learn much.

I’m simply testing with my multimeter at this stage. The whole thing is sitting on bread boards. I am familiar with LEGO wiring diagrams.

Hi,

After successfully running trains in Rocrail using the MTC4PU I now want to try the MTC4PF.

After successfully loading the program onto the esp 12 and what looks like me to normal behaviour in serial monitor. I can’t get it to talk to Rocrail. After connecting the power. Train light comes on at pin D0, indicator led on pin D8 is off. Battery voltages measured on pins that control shield. Battery voltage measured on motorshield power in. 2.77 volts measured on other pins of the shield. No voltage on motor outlets. Controller doesn’t respond to commands from Rocrail.

What do I do next ?
