WF121

The Wi-Fi Module for IoT Applications

The WF121 is a stand-alone Wi-Fi module providing fully integrated 2.4 GHz 802.11 b/g/n radio, TCP/IP stack and a 32-bit microcontroller (MCU) platform for embedded applications requiring simple, low-cost and low-power wireless IP connectivity. It also provides flexible peripheral interfaces such as SPI, I2C, ADC, GPIO, and timers to connect various peripheral interfaces directly to the WF121 Wi-Fi module. The WF121 Wi-Fi module also allows end-user applications to be embedded onto the on-board 32-bit MCU, using a simple BGScript™ scripting language and free-of-charge development tools. This eliminates the need for and additional MCU and enables end-users to develop smaller and lower cost Wi-Fi devices. The WF121 can also be used in a modem-like mode in applications where the external MCU is needed. The 802.11 access point and HTTP server functionality are also included for easy configurations and direct connections with phones, tablets, and PCs. With an integrated 802.11 radio, antenna, single power supply, and CE, FCC, and IC regulatory certifications, the WF121 provides low-risk and fast time-to-market for applications requiring Wi-Fi connectivity.
