 * **ALTERNATIVE**: No modification required on the PZEM-04T. Rather than using the 3.3V output from the Wemos D1 Mini to power the PZEM-04T, use the same 5V buck converter output (also used to supply power to the display and the Wemos D1 Mini) to power the PZEM-04T. This eliminates the need for the resistor and the need to modify the PZEM-04T at all.
