Microchip Technology Inc. has unveiled the integration of its WiFi modules from the recent Roving Networks acquisition into its flexible, modular Explorer development systems supporting all of its 8, 16 and 32bit PIC MCUs. According to the company, the RN-131 and RN-171 PICtail/PICtail Plus daughter boards use a simple serial interface to connect with any PIC MCU.

The Roving Networks RN-171 and RN-131 fully certified modules from Microchip are networking solutions that include a true 802.11 b/g radio, base band processor, TCP/IP stack and a host of networking application features. No external processor drivers are required, enabling WiFi connectivity for 4, 8, 16 and 32bit processors. This on-board-stack approach significantly reduces customers' integration time and development effort in a small form factor, while offering ultra-low power consumption (down to 4µA in sleep, 3 mA in receive and 120mA in transmit mode), detailed the company.

The RN-131 PICtail daughter board (Part # RN-131-PICtail) is available for $44.95 each. Likewise, the RN-171 PICtail daughter board (Part # RN-171-PICtail) is available for $39.95 each.
