                      Product Overview

                      WF121 Wi-Fi module with internal chip antenna. Bluegiga WF121 is a stand-alone Wi-Fi module providing fully integrated 2.4GHz 802.11 b/g/n radio, TCP/IP stack and a 32-bit micro controller (MCU) platform for embedded applications requiring simple, low-cost and low-power wireless IP connectivity. WF121 also provides flexible peripheral interfaces such as SPI, I2C, ADC, GPIO, Bluetooth coexistence and timers to connect various peripheral interfaces directly to the WF121 Wi-Fi module. It allows end user applications to be embedded onto the on-board 32-bit MCU using a simple Bluegiga BGScript™ scripting language and free-of charge development tools. Suitable for use in PoS terminals, RFID and laser scanners, Wi-Fi internet radios and audio streaming products, Wireless cameras, portable navigation devices, portable handheld devices, Wi-Fi medical sensors and wireless picture frames.
