WiFi 6 Click

Description of product


WiFi 6 click features Bleugiga’s WF121-A self-contained WiFi module. With a fully integrated radio and 32-bit microcontroller, this module is ideal for embedded applications. WiFi 6 click is designed to run on a 3.3V power supply. It communicates with the target MCU the mikroBUS™ UART (TX, RX), SPI, or IC2, with additional functionality provided by CTS pin (in place of default mikroBUS™ INT pin).

SPI interface can be accessed by jumpers on the click board.

mikroProg connector

A mikroProg connector allows to update the firmware of the internal PIC32.

WF121-A WiFi module

The module’s 2.4GHz band radio is fully compliant with IEEE 802.11b/g/n and offers excellent radio performance.

It allows the end user applications to be embedded onto the integrated PIC32MX695H, a 32-bit 80MHz microcontroller with 128KB RAM and 512KB Flash memory, for development of lower-cost and smaller sized products. Also, integrated on-board is a single power supply.

Power saving client mode

In WiFi client mode, the WF121 radio core automatically powers on the RF circuitry only when needed. The WiFi core processors support automatic sleep modes when not communicating actively, allowing very low idle consumption. When used as an access point, the radio core must receive constantly and cannot enter sleep modes.

Integrated firmware on the module

The integrated firmware provides WiFi and networking stack services (TCP/IP, UDP, DHCP, DNS).
