datasheet ESP8266-12F

ESP12F Breakout Board

ESP12F Breakout Board Notes:

  • exposed GPIO to set different working modes
  • more info on the modes in the datasheet, here or here
  • the default baud rate of the ESP12F is 115200
  • it is possible to use the software serial to communicate with at 115200, but the communication will not be reliable; it is therefore recommended to lower it to 9600-19200, with the AT command AT+CIOBAUD=9600

HC-05 Breakout Board

HC-05 Breakout Board notes:

  • the HC-05 module can work in two modes, communication and configuration
  • configuration mode can be activated by connecting the KEY pin to 3.3v (use a jumper on the breakout board)
  • default baud rate for both modes is 38400, it is possible to change the baud rate of the communication mode with AT+UART=9600,0,0
  • more info about the modes and the configuration here
