IEEE 802.11 b/g Wi-Fi® Modules Providing Complete
2.4 GHz Wi-Fi Connectivity for PIC®Microcontrollers
MRF24WG0MA/MB
Summary

Features

Supporting the Internet of Things, Microchip’s
MRF24WG0MA/MB IEEE 802.11 b/g modules provide Wi-Fi
connectivity to PIC microcontroller based designs. These
regulatory agency certified and standards based Wi-Fi
modules are highly suitable in many embedded products
where low power consumption, complete Internet Protocol
services and flexibility are necessary for the embedded
wireless market. The MRF24WG0MA/MB Wi-Fi modules
together with Microchip’s large selection of peripheral rich
PIC microcontrollers are ideally suited for easily adding Wi-Fi
connectivity to your embedded products.
The MRF24WG0MA/MB modules together with the PIC
microcontroller provide a complete Wi-Fi solution. Advanced
IP services such as web server, data encryption (SSL) and
FTP features are provided via the free license TCP/IP source
code stack available for 8, 16, or 32-bit PIC microcontroller.
