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

SKU: TEL0047

The shield uses WizFi210, a low-power WiFi module with dynamic power management: Standby mode saves power when idle, and it wakes only for work. It bridges TTL serial to IEEE802.11b/g/n, letting any TTL serial device connect wirelessly for remote control. Integrated communication protocols/encryption and Arduino compatibility enable easy integration into Arduino-based projects.

    Parameter Details
    Wifi Chip WizFi210
    Radio Protocol IEEE 802.11b/g/n Compatible
    Supported Data Rates 11, 5.5, 2, 1 Mbps (IEEE 802.11b)
    Modulation DSSS and CCK
    RF Operating Frequency 2.4 - 2.497 GHz
    Antenna Options Chip antenna and U.FL connector for external antenna
    Networking Protocols UDP, TCP/IP (IPv4), DHCP, ARP, DNS, HTTP/HTTPS Client and Server(*)
    Power Consumption(Typical) Standby = 34.0 µA Receive = 125.0 mA Transmit = 135.0 mA
    RF Output Power (Typical) 8dBm ± 1dBm
    Security Protocols WEP, WPA/WPA2–PSK, Enterprise, EAP-FAST, EAP-TLS, EAP-TTLS, PEAP
