MRF24WG0MA PICtail™/PICtail Plus Daughter Board Information Sheet Overview The MRF24WG0MA PICtail/PICtail Plus Daughter Board is a development and demonstration board for evaluating Wi-Fi® connectivity using PIC® microcontrollers and the MRF24WG0MA module. Features • MRF24WG0MA Wi-Fi module with 802.11 b/g connectivity • Daughter board supports PICtail and PICtail Plus connectors (for more information, see MRF24WG0MA PICtail™/PICtail Plus Daughter Board Schematic) Getting Started To get started, an Explorer 16 or PICDEM.net™ 2 development board is required. Alternatively, a PIC32 Starter Kit with a PIC32 I/O Expansion Board can be used. With the appropriate hardware available, download Microchip TCP/IP Stack and follow the Getting Started chapter of the TCP/IP Stack Help.
