nRFready Desktop Hardware Description 2 nRF6901-nRFready Desktop USB dongle
2.1 Introduction
The nRFready Desktop USB dongle is a single chip ultra miniature dongle that us the nRF24LU1+ SoC solution from Nordic Semiconductor. This dongle is a complete and production-ready reference design for the nRF24LU1+ bad USB dongle down to the actual mechanics and plastic.
The whole circuitry except the antenna is placed inside the USB connector itlf to significantly reduce length of the USB dongle, yet offers an operating range comparable to full size USB dongles.
The USB dongle is a production ready design that has Gerber files and Altium Designer 6 files that can be ud in their current form or modified to develop your own design.
The nRFready Desktop USB dongle is USB compatible but not USB compliant. To be USB compliant the USB connector ud must comply with the connectors outlined in the USB standard. Non compliance will be the ca for all ultra-miniature USB dongles fitting the electronics inside the connector. All other USB compliance test parameters are met. The design has been tested in a certified lab on key RF parameters for the purpo of demonstrating compliance with ETSI 300-440, FCC CFR 47 paragraph 15.247 and Industry Canada RSS-210 Issue 7.
