Hi Mike,
Can the VH400 and the ESP8266 be powered from the same supply? The VH400 says it takes 3.5V – 20V input. The ESP8266 board I ordered is UBB powered so goes up to 5 Volts. Can I tie the VH400’s VIN & GND to the ESP8266’s VIN and GND to power the VH400?
The VH400 analog out is 0-3V and the ESP8266 board’s analog A0 input pin range is 0 – 3.3V, so I think, I can connect the VH400’s analog out directly to the A0 pin on my ESP8266 board – can you please confirm?
Thank you again for all the help.
