WiFi2 click features the HLK-M30 WiFi module with a built-in TCP/IP protocol stack. The click is designed to run on a 3.3V power supply; it communicates with the target MCU over an UART interface and the following mikroBUS™ pins: AN, RST.
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.
