I've ordered one and have been notified it shipped and to expect delivery in about a month. I'll see whether there's a simple way to add auto reset. Do you have a recommended value for the capacitor? Is this the DTR Only Reset Mode or Wifio Reset Mode?

I couldn't get it to work on an ESP-12E with 0.1uF but it did work with 0.33uF and 1.0uF. The diode I used was a BAT42 Schottky.

It is DTR Only, circuit shown in the attached image. The resistor on RESET wasn't used as there was already a 12K resistor on the ESP-12E. I had to add the one on GPIO0, 10K is what I used.

While clever, this auto-reset mode has the disadvantage that both DTR and RTS are required. That's less of an issue in this case since the USB interface is included on the board.
not the link you wanted ..
