WiFi 4 click

WiFi 4 click carries SPWF01SA, a complete standalone WiFi module with a single-chip 802.11 b/g/n transceiver, a 32-bit STM32 MCU, along with a built-in 2.4 GHz ISM band antenna. The onboard module has 1.5 MB of internal flash and 64 KB of RAM, plus a fully integrated TCP/IP protocol stack with added web server and application service capabilities. WiFi4 click communicates with the target MCU through the mikroBUS UART interface, but the board also features additional 14 GPIO pins. Uses a 3.3V power supply only.
