In the last few months the ESP8266 series of WiFi SoC (System on a Chip) has exploded into the electronics market, thanks to the low cost and relative ease-of-use. The ESP8266 allows you to easily add a serial-based WiFi device to almost any platform - and this includes Arduino-compatibles such as our Eleven and others.
However the pinouts on the ESP-01 version of the module have been somewhat unruly for use - so we've come up with a conveinent new shield for Arduino that allows plug and play use of the ESP8266 in minutes - the Freetronics ESP-01 WiFi Module Shield:
Our new shield has a socket that's perfect for the ESP-01 module, and addresses all the needs of the ESP8266 - such as:
- 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
So don't fiddle with jumper wires or sub-standard power supplies - order your the Freetronics ESP-01 WiFi Module Shield today. They're in stock right now for only $14 including GST.
