ESP8266-01 and FTDI FT231XS Schematic issue?
Posted: Wed Jun 01, 2016 8:33 amI created a new design using the FT231XS chip that has RTS and DTR pins to allow me to program an ESP8266-01 module without holding down a button and powering it up. The two NPN transistors used in other designs should take care of things.
Right now in the Arduino IDE things look fine.
-power is going where it should
-the FTDI com port appears
-programming leds blink for a second but the sketch will not upload
Can someone take a look at the attached schematic to see if anything obvious was left out? I'll poke around with the oscilloscope over the next few days to find the problem.
