1 Introduction
This document describes the nRF24LU1 USB Dongle reference design with the Nordic
Semiconductor nRF24LU1 Embedded nRF24L01 compatible RF Transceiver with USB.
Figure 1 shows the nRF24LU1 USB Dongle reference design.
Figure 1 - nRF24LU1 USB Dongle
The nRF24LU1 USB Dongle has been developed as a complete reference design for the nRF24LU1.
It is a production ready design that has Gerber files and Altium Designer 6 files that can be used in
their current form or modified to develop your own design. The reference design is USB certified and
has been EMC tested. RF qualification test reports and USB compliance report are included on the
CD.
The nRF24LU1 will typically be used in a USB dongle for mouse, keyboard, remote control, data
collection and transfer, communication with peripheral units etc.
The nRF24LU1 has built in the nRF24L01 compatible transceiver, making it a perfect match for
nRF24L01 based equipment. In addition to the transceiver, the nRF24LU1 has a full speed USB 2.0
compliant device controller, an 8-bit 8051 MCU and 16kB of flash memory. The voltage regulator is
integrated in the nRF24LU1, so the nRF24LU1 can be supplied directly from the USB.
The key features are:
•Reference design for a compact USB dongle for wireless peripherals
•Production ready
•Compact form factor
o12 × 23mm excluding USB connector
o12 × 32mm including USB connector
•FCC, ETSI and USB qualified
•Full-speed USB 2.0 (up to 12 Mbps) compliant device controller
•Fully nRF24L01™ compliant 2 Mbps 2.4GHz RF transceiver
•Powerful enhanced 8051 microcontroller
•16 kbytes of embedded flash memory
•2 kbytes of SRAM
•Low active components count; the nRF24LU1 and a single 16MHz crystal
•Very compact low cost PCB antenna and matching network
•Seamless integration with nRF24LU1 Software Development Kit.
•Complete set of deliverables including design files, BOM and comprehensive documentation
•Supports application development directly on the dongle
