Pzem 004t energy module

Post by giovamec » Wed Jul 03, 2019 1:05 pm

Dear Team
I'm your customer
and I'm trying to use "Pzem 004t energy module" with MAXI. this works only on the pin headers of serial 2 (RX2;TX2 pin 17 and 16).
I tried on serial 1 or with a soft serial on the other pins but with a negative result.
could you tell me which pins to try? ie on which pins there are lower protection resistances to be able to read the signal?
Giovanni
