Nordic Semiconductor’s new nRF24LU1+ is a USB dongle single-chip solution for ultra-low power (ULP) wireless peripherals. The nRF24LU1+ combines the performance of Nordic’s existing nRF24L01+ 2,4 GHz radio transceiver with the extended feature set of the nRF24LU1 USB dongle single-chip device.
The device integrates a full-speed USB 2.0 compliant device controller with an 8-bit Flash microcontroller and the nRF24L01+ transceiver. It includes an integrated voltage regulator that allows the chip to be powered directly from a USB bus, removing the requirement for an external voltage regulator. In addition, on-chip Flash memory eliminates the need for an external EEPROM memory. The only external components the nRF24LU1+ chip requires are a 16 MHz crystal, decoupling, matching network and antenna.
The nRFready USB dongle (pictured) is a complete and production-ready reference design for the nRF24LU1+ USB dongle, including mechanics and plastic. It takes advantage of the single-chip architecture and the small 5 x 5 mm form factor to place the nRF24LU1+ inside the USB connector to significantly reduce the length of the USB dongle.
The nRF24LU1+ is supported by Nordic’s new nRFgo evaluation and development platform, the core of which is the nRFgo Starter Kit which provides a unified platform for the company’s ULP wireless offerings. The nRF24LU1+ Development Kit works with the nRFgo Starter Kit and together they include everything needed to evaluate and develop applications on the chip.
The Software Development Kit (SDK) includes full support for Keil µVision IDE, including a plug-in for the nRFProbe hardware debugger. A library of hardware abstraction layers, verified USB firmware stack, Gazell RF protocol stack and complete example applications make it easy for firmware developers to take advantage of all the nRF24LU1+’s advanced features.
