ESP-12E/12F Development Board


A multipurpose ESP8266 ESP-12E/12F Development Board to create your own IoT devices.
ESP-12 Development board is a small foot print development board and deployment board. A very simple board that can be easily assembled and very flexible to use. The pin out legend corresponds to use with Arduino framework for esp8266.

Why did you make it?
For codetesting and development of devices with different sensor modules etc.

  • You can connect most common USB to Uart programmers directly to the board, to flash or program your ESP-12 Module.
  • There is a AMS1117-3.3V voltage regulator on board which accepts input voltages from 3.7 to 12V.
  • The board contains the button which is connected to the reset pin.
  • You can use a screw terminal to connect an external power source.
  • TX and RX pins can be converted into GPIO, so that you can connect 4 external modules (i.e. control 4 relais or LEDs etc.).
  • Breakout for up to 6 i2c modules (please note that the voltage regulator can provide maximum 250mA, so it will not work with power hungry i2c modules).
  • For ESP-12 module there is a convenient female or mail pinheader connector.

What you get?
A single ESP-12 PCB without pin headers, just a board.

Available pins:

  • 9 GPIO pins: GPIO0, GPIO2, GPIO4, GPIO5, GPIO12, GPIO13, GPIO14, GPIO15, GPIO16
  • 1 analog pin (ADC pin)
  • Powerdown (CH_PD pin)
  • VCC (5V & 3.3V), GND

How to solder?
First solder the pin headers to the board and voltage regulator AMS1117-3.3V, then solder the ESP-12 module to the PCB, also don’t forget to connect GPIO-15 to the GND pin with a solder bridge.
