The RN-131 and RN-171 PICtail™/PICtail Plus daughter boards are the first two products developed by Microchip based on Roving Networks modules. These modules use a simple serial interface to connect with any PIC microcontroller, and expand Microchip’s wireless portfolio with the industry’s lowest power consumption combined with an integrated TCP/IP stack in a certified Wi-Fi solution.
The Roving Networks RN-171 and RN-131 fully-certified modules, from Microchip, are comprehensive networking solutions that include a true 802.11 b/g radio, baseband processor, TCP/IP stack and a host of networking application features. No external processor drivers are required, enabling Wi-Fi connectivity for 4, 8, 16 and 32-bit 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 4 µA in sleep, 35 mA in receive and 120 mA in transmit mode.
The boards allow designers to add WiFi connectivity to the entire portfolio of PIC microcontrollers, without integrating a TCP/IP stack and whilst using standard development tools, which speeds time to market and reduces R&D resources.
