Microchip Technology MRF24WB0MA and MRF24WB0MB are the first certified embedded Wi-Fi® modules following the ZeroG acquisition. These 2.4GHz Microchip Technology transceiver modules feature extremely low receive currents for longer battery life. The IEEE 802.11 module firmware has an easy-to-use API driver interface to the Microchip free TCP/IP Protocol stack and to Microchip PIC® microcontrollers. The low-power MRF24WB0MA and MRF24WB0MB embedded Wi-Fi modules remove the complexity and cost of developing RF circuitry and obtaining agency certification. The MRF24WB0MA has an integrated PCB antenna, matching circuitry, and supports Wi-Fi with the free TCP/IP protocol stack. The MRF24WB0MA module connects to hundreds of PIC microcontrollers via a 4-wire SPI interface. These Microchip Technology RF transceiver modules are optimized for use in a variety of applications, including utility and smart energy, consumer electronics, industrial controls, remote device management, retail, and medical / fitness / healthcare.

Additional Resources

Microchip DV102411 Wi-Fi® Comm Demo Board combines Microchip's best-in-class 32-bit PIC32 microcontroller family with its low-power MRF24WB0MA agency-certified, IEEE 802.11, embedded Wi-Fi radio transceiver module. Microchip Wi-Fi Comm Demo Board is preloaded with demo software for the user to explore the features of the MRF24WB0MA Wi-Fi module. It is also expandable through an expansion interface that allows the user to extend its functionality by adding various sensor expansion boards. The Microchip Wi-Fi module and TCP/IP stack enable connectivity for control and communication over the Internet. The PIC32 MCU family provides the performance and features to simultaneously process both Wi-Fi communications and a large number of other functions, including audio, graphic displays and touch sensing, and general system command-and-control operations.
