WiFi Shield V2.2 for Arduino (802.11 b/g/n)

An 802.11 b/g/n WiFi shield for Arduino based on the WizFi210 module. This shield bridges TTL serial communication to wireless networking, letting you add WiFi connectivity to any Arduino project via the serial host interface. With ultra-low standby power (34µA) and dynamic power management, it's well suited for battery-powered and IoT applications.

The WizFi210 module supports a comprehensive range of security protocols including WPA2-PSK and enterprise authentication, along with networking protocols such as TCP/IP, UDP, HTTP, HTTPS, DHCP, and DNS. The shield features both an onboard chip antenna and a U.FL connector for attaching an external antenna.

Key Features

  • 802.11 b/g/n WiFi – Up to 11Mbps data rate (802.11b)
  • Ultra-Low Power – 34µA standby, 125mA receive, 135mA transmit
  • Fast Boot – Under 20ms startup time
  • Comprehensive Security – WEP, WPA/WPA2-PSK, Enterprise, EAP-FAST, EAP-TLS, EAP-TTLS, PEAP
  • Dual Antenna Options – Onboard chip antenna plus U.FL connector for external antenna
  • Serial Host Interface – Arduino-compatible TTL serial communication
  • CE, FCC, KCC Certified – Meets international wireless compliance standards
  • Wide Temperature Range – –40°C to +85°C operating temperature
