      I 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.

        Hi @miker
        Nice to see old OLED board creator there 😉

        Your schematic looks good, at which speed did you tried to upload ? Did you programmed the FTDI chip with FT_PROG to see pin setup and functions ?
