Overview
The PmodWiFi is an interface board for the Microchip® MRF24WB0MA Wi-Fi™ radio transceiver module.
1 Functional Description
The PmodWiFi provides IEEE 802.11b/g/n support for embedded applications at data rates of 1 and 2Mbps. It is
designed for use with Microchip microcontroller families (PIC18, PIC24, dsPIC33, and PIC32) and the Microchip
TCP/IP Stack (a free Microchip Application Libraries download including example applications and source code).
The TCP/IP Stack is available at www.microchip.com/wireless.
1.1 Interface
The primary communications interface with the PmodWiFi is an SPI bus. An RST pin provides the host with an
active low, asynchronous hardware reset for the PmodWiFi. The PmodWiFi also provides an active low interrupt
indicator pin (~INT), which is asserted low by the PmodWifi when data is available for the host device. The ~INT
line is de-asserted high after the data transfer is complete. The SPI SCK speed can be up to 25 MHz.
