New Low-Power Embedded Wi-Fi Solutions for the IoT

Microchip Technology recently launched four low-power, highly integrated solutions that enable Wi-Fi and networking capability to be embedded into a wide variety of devices, including Internet of Things (IoT) applications. These four modules provide complete solutions for 802.11b/g/n and are industry-certified in a variety of countries.Microcontroller  MRF24

The new RN1810 and RN1810E are stand-alone, surface-mount WiFly radio modules that include a TCP/IP stack, cryptographic accelerator, power management subsystem, 2.4-GHz 802.11b/g/n-compliant transceivers, and 2.4 RF power amplifier. You can pair them with any microcontroller and configure them using simple ASCII commands. WiFly provides a simple data pipe for sending data over a Wi-Fi network, requiring no prior Wi-Fi experience to get a product connected. Once configured, the device automatically accesses a Wi-Fi network and sends and receives serial data. The RN1810 features an integrated PCB antenna. The RN1810E supports an external antenna.

The new MRF24WN0MA and MRF24WN0MB are Wi-Fi modules that interface with Microchip’s PIC32 microcontrollers and support Microchip’s MPLAB Harmony integrated software framework with a TCP/IP stack that can be downloaded for free at www.microchip.com/harmony. The modules connect to the microcontroller via a four-wire SPI. They area an ideal solution for low-power, low-data-rate Wi-Fi sensor networks, home automation, building automation, and consumer applications. In addition, an MRF24WN0MA has an integrated PCB antenna, while the MRF24WN0MB supports an external antenna.

The RN1810/E and MRF24WN0MA/B are now available and start at $13.05 each in 1,000-unit quantities. Also available is the $34.95 MRF24WN0MA Wi-Fi PICtail/PICtail Plus Daughter Board, a demonstration board for evaluating Wi-Fi connectivity using PIC microcontrollers and the MRF24WN0MA module (part # AC164153). In addition, a $49.95 RN1810 Wi-Fi PICtail/PICtail Plus Daughter Board is available today with a fully integrated TCP/IP stack and USB interface for easy plug-and-play development with a PC (part # RN-1810-PICTAIL).
