WF121 is a stand-alone Wi-Fi module providing fully integrated 2.4GHz 802.11 b/g/n radio and a 32-bit microcontroller (MCU) platform for embedded applications requiring simple, low-cost and low-power wireless TCP/IP connectivity, also providing flexible interfaces for connecting to various peripherals.WF121 allows end user applications to be embedded onto the on-board 32-bit microcontroller using a simple Bluegiga BGScriptTM scripting language - without the need for additional MCU. WF121 can also be used in modem-like mode in applications where the external MCU is needed.
With an integrated 802.11 radio, antenna, single power supply, and regulatory certifications, WF121 provides a low-risk and fast time-to-market for applications requiring Wi-Fi connectivity.
