I have this adafruit-feather-huzzah-esp8266: https://learn.adafruit.com/adafruit-feather-huzzah-esp8266/pinouts

and I want to connect a Fona board. But I am not certain which pins have the aforementioned software serial pins necessary to make the required connections. https://www.arduino.cc/en/Reference/SoftwareSerial

from the Fona tutorial: https://learn.adafruit.com/adafruit-fona-3g-cellular-gps-breakout/arduino-wiring

which pins on the adafruit-feather-huzzah-esp8266 should I use for pin: "TX connects to digital 3 (9 on Leo/Micro, 10 on Mega) "

where the feather doesn't have this a pin3. similarly, which pins correspond to RST and RX?

  • you want RX-TX, TX to RX, reset to whatever you have free. – dandavis Apr 3 '17 at 17:28
  • I'll try it, although in the tutorials it is not configured that way – j0h Apr 3 '17 at 18:04

    if you need softwareserial, as opposed to hw, on the ESP pins 4+5 are going to be your best bet. if you don't need SPI, 13+15 will work as well. – dandavis Apr 3 '17 at 18:11
