Cytron ESP8266 WiFi Shield

Because of IoT (Internet of Thing), everything is connected to the Internet, a crucial element is WiFi that provides a wireless connection to the Internet. It has been carrying ESP module and many have used it. However, it is not user-friendly enough for a beginner. The module is 3.3V powered and the pins are not properly broken out. Integrating it to PIC or Arduino will require some skill and electronics interface.

With this ESP WiFi shield, it will be plug and use for Arduino user. The shield comes preassembled with ESP8266-12WROOM-02 module which offers WiFi connection to your Arduino board or project. No additional soldering or wiring needed, just stack the shield on toGenuino UNO, CT-ARM, CT-UNO, Genuino Mega or any compatible Arduino main board, select the pins for Serial communication with mini jumpers and the hardware connection is completed! The focus in program development, and the good news, there are plenty of libraries that you can utilize, we will show you the steps!

 I had been used many wifi shields but it so difficult for connect with IOT. But with using this Cytron for me really easy to make program combine with Arduino UNO. I make my friend project and i always suggest for using this Wifi shield.


Arduino R3 Layout, compatible with:
  • CT-UNO
  • CT-ARM
  • Genuino UNO R3
  • CIKU (need to develop library)
  • Genuino Mega
  • Arduino Leonardo
  • many other Arduino compatible mainboards

  • Separate 3.3V voltage regulator for ESP8266-12 WROOM-02 module, 500mA max output
  • Each and every board is preassembled and tested before it is being shipped out to you
  • UART/Serial communication pins can be configured/selected via mini jumpers:
  1. USB - Direct to Arduino USB to Serial pin for flashing ESP8266 directly
  2. D0/D1 - Hardware Serial pin of Arduino UNO and CT-UNO
  3. D2, D3, D8, D9, D10, D11, D12, D13 - Software serial pins
  • 802.11 b/g/n
  • Support Wi-Fi Direct (P2P), soft-AP
  • Integrated TCP/IP protocol stack
  • Integrated TR switch, balun, LNA, power amplifier and matching network
  • Integrated PLLs, regulators, DCXO and power management units
  • Integrated low power 32-bit CPU could be used as an application processor
  • +19.5dBm output power in 802.11b mode
  • Basically, Rev2.0 utilize WROOM-02 instead of ESP8266-12 as the WiFi module
