ESP 01 WiFi Module Shield

This product has been retired Listed here for reference only

The ESP 01 WiFi Module Shield lets you easily plug an ESP 01 WiFi Module into your Arduino

Note: ESP 01 WiFi Module not included

The ESP 01 is a very popular module based on the ESP8266 chipset that lets you add WiFi support to your project However, you can’t connect it directly to a typical Arduino because it uses 3 3V data pins for communication not 5V and it requires a high current 3 3V power supply It also needs a mode pin to be set correctly in order to operate

This shield takes care of all those problems and lets you simply plug in your ESP 01, load a sketch, and communicate with it directly from your Arduino Easy

Features

• 3 3V regulator dedicated to the module to ensure sufficient current capacity
• Logic level shifters on TX/RX lines: compatible with both 3 3V and 5V Arduino models
• Selectable TX/RX pins: use D0/D1 for hardware serial, or D2 D7 for software serial
• CH_PD pin on ESP 01 module pre biased for correct operation mode
• Extra ESP 01 pins broken out for your own connections
• Prototyping area with 5V and GND rails
• All Arduino headers broken out for easy connections
• Stacking R3 style Arduino headers including the ICSP header
