NOTE: we no long stock this module any more. Please check the ESPToy instead.

The ESP8266 Serial-to-WiFi module is a compact WiFi module. Use it with any microcontroller that has hardware serial (TX/RX) pins such as the Arduino.

Pin mapping:

  • Note: the middle 4 pins (GPIO0, 2, CH_PD, RST) must be pulled high to VCC to enable AT commands.
  • Note: to connect the module to 5V Arduino, please use a level shifter, or resistor+zener, or at least a simple series resistor on the URXD line of the module, because the pins on the module are only 3.6V tolerant.
