Microchip MRF24WB0MA IEEE 802.11 – Wi-Fi Module

MRF24WB0MA Built-in PCB Antenna IEEE 802.11 – Wi-FiIn CISIUM we understand the importance of RF communications, and more specifically the Wi-Fi (IEEE 802.11), a standard communications integrated in modern smart phones, tables and laptops. Now it is available the integration of Wi-FI communications in our embedded systems form the hand of Microchip.

Microchip has added 802.11 wireless communications to its lineup of wireless technologies for the embedded market. The Microchip embedded Wi-Fi module contains the MRF24WB0MA FCC and Wi-Fi certified module.

The Wi‐Fi MRF24WB0MA allows us to quickly create a direct connection to the Internet by seamlessly connecting to standard 802.11b/g access points. In managing the connection, the MRF24WB0MA module controls the MAC and baseband layers and is connected to the host MCU via an SPI port.
