The WiFi 4 Click Board™ Board carries the ST 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 WiFi 4 Click Board™ carries the ST 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 Board™ 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).
