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 click is designed to run on a 3.3V power supply. It communicates with the target MCU over an UART interface (with additional functionality provided by Reset and Ready To Send pins, in place of default mikroBUS™ RST and CS pins).

SPWF01SA module

The SPWF01SA module has 1.5 MB of internal flash and 64 KB of RAM, and can achieve up to +18 dBm of output power.

In standby mode the module uses only 34 uA, while in sleep mode the typical power consumption is 15 mA.

Additional GPIO pins

The 14 additional GPIO pins that line the edges of the board have alternate functions like SPI, ADC, I2C, DAC (although access to those functions depends on the firmware version loaded in the module).
