WiFi 4 Click Board, mikroE

Now easily integrate WiFi communication to your existing or new device with the WiFi 4 Click Board! This simple and compact click board features an intelligent WiFi module, called SPWF01SA, with a single-chip 802.11 b/g/n transceiver. The chip is also integrated with a STM32 32-bit microcontroller and a built-in micro 2.4 GHz ISM band antenna. WiFi 4 click also includes an integrated fully-featured TCP/IP protocol stack with added web server and additional application service capabilities. The onboard module is provided with 1.5 MB of integrated flash memory and 64 KB of RAM. WiFi 4 click uses the mikroBUS UART interface to communicate with the target board microcontroller. It also features 14 additional GPIO pins.

It is designed to use a 3.3V power supply only. WiFi 4 click is ideal for connecting equipment to the Internet, creating smart appliances, wireless data loggers, home automation, etc.

IC/module: SPWF01SA—A Complete Standalone WiFi Module

Configured around a single-chip 802.11 b/g/n transceiver and a 32-bit STM32 MCU, SPWF01SA chip provides easy integration of wireless connectivity in the design. It comes embedded with a built-in 2.4 GHz ISM band antenna. This module is highly suited for fixed, mobile and even battery-operated wireless applications thanks to its low power consumption and small package.

Communication with Target MCU

WiFi 4 click communicates with the target board microcontroller via mikroBUS UART pins. Additional functionality is provided by Reset and Ready To Send pins (in place of default mikroBUS RST and CS pins).

Additional GPIO pins

It is also provided with an extensive GPIO suite with additional 14 GPIO pins. The extra GPIO pins that line the edges of the board can have alternative functions (SPI, ADC, I2C, DAC), however, access to those functions depends on the firmware version in the module.
