Description
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 BGScript
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.
