Microchip PICtail WiFi Development Kit RN-131-PICtail

The RN-131-PICTAIL and RN-171-PICTAIL evaluation boards work seamlessly with the Microchip Technology PIC18 Explorer Development Board. The evaluation boards plug into the PICtail modular connector on the PIC18 Explorer
Board, and add wireless functionality to PIC18-based microcontroller designs.
The evaluation boards are preloaded with firmware to simplify integration and minimize application development. In the
simplest configuration, the hardware only requires four connections (PWR, TX, RX, and GND) to create a wireless data
connection. The microcontroller can communicate with the boards via the UART and SPI interfaces, and can drive LEDs,
wake the boards, and reset them. The evaluation boards are updated and controlled with a simple ASCII command
language. Once the boards are set up, they can scan to find an access point, associate, authenticate, and connect over any Wi-Fi network.
