- Sat Aug 06, 2016 11:23 am #52288 Did You read the datasheet? ( http://download.arduino.org/products/UN ... N-v4.3.pdf ) "Operating Voltage: 3.0V - 3.6V", and this is only for ESP (I dont know about SPI Flash type on Your module). IMHO the flash is corrupt because power supply was out of range...

- Sat Aug 06, 2016 11:28 am #52289 It was operating at 2.75 for 7 hours, I have also tried new batteries (Brand new Duracell) and also using the 3.3v line in from my programmer has the same effect it will not start.

I now have it working with the line in from the programmer and it is operating at 2.89 so I guess the data sheet is incorrect.
