Cytron ESP8266 WiFi Shield

 

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

 

• 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 main boards
• Seperate 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 ship out to you
• UART/Serial communication pins can be configured/selected via mini jumpers:
  • USB - Direct to Arduino USB to Serial pin for flashing ESP8266 directly
  • D0/D1 - Hardware Serial pin of Arduino UNO and CT-UNO
  • 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 application processor
• +19.5dBm output power in 802.11b mode
• Basically Rev2.0 utilize WROOM-02 instead of ESP8266-12 as the WiFi module
