TCP/IP client of server

WiFi2 click can be set up both as a TCP/IP client or server. You can configure it with either a static or dynamic IP address. Use the mikroBUS™ AN line (DEF on this click) to reset WiFi2 to default factory settings if needed.

Security and network protocols

WiFi2 click supports standard security authentication systems (WEP64/WEP128/ TKIP/ AES, WEP/WPA-PSK/WPA2-PSK); as well as multiple network protocols (TCP/UDP/ DHCP/DNS). All these features make WiFi2 click ideal for home automation applications, remote controls, telemetry etc.

PBC antenna

The click features a PCB trace antenna, designed for the 2400–2483.5 MHz frequency band.
