This is a Makerdiary not a AduFruit. Works awesome just make sure to reference the Brand of device. Thank you Seller for giving a better description of the product.

Épicamente barato y all-in-one tool.

Il prodotto che ho ricevuto aveva il bootloader con una versione precedente alla 0.4.0 (0.2.3) che comporta l'impossibilità di flashare un nuovo firmware senza l'uso di un secondo device esterno. Data questa caratteristica consiglio di acquistare la board originale Nordic o di prendere in accoppiata la scheda per flashare il bootloader aggiornato. Consiglio al venditore di indicare anno di produzione della board e versione nel bootloader

Works, no problems.

É un compatibile, Non è il prodotto originale e si vede. Non funziona e non permette la scrittura del FW

I am currently working on a project and I wanted to explore the possibilities of the Thread protocol. This device was somewhat cheaper than the Nordic devices, so this is the device I went for.I think it's important to tell you up front: This device is not going to be as simple as including a new repository in your Arduino IDE, download some libraries to include and you can get your programs running. It's not an Arduino or Arduino-supported board at all. It requires you to have some knowledge about using bash, downloading, installing and using the gnu ARM toolchain (arm-none-eabi-gcc) and doing some research yourself as the github is not up-to-date.I have used it as an 802.15.4/Thread interface for a Raspberry Pi 3B as a border router. I've followed the instructions of the Makerdiary wiki, but it's hopelessly out of date. Instead, you need to download and use the openthread/ot-nrf538xx repo and follow the installation instructions there. After building the files in the ot-528xx repo, you should end up with a build folder which includes an ot-rcp file, which you can convert to a hex file, and then convert the hex file into a uf2 file, which you can finally load onto your dongle and use it as an rcp for a border router.Get your info from openthread.io, the openthread github and forget about both the Makerdiary wiki/git and the Nordic Semiconductor stuff; you won't need those. Openthread.io and the openthread/ot-nrf528xx repos are all you need!

Viele Stunden mit diesem Ding verplempert. Letztendlich habe ich das Orignal für weniger Geld bekommen und konnte endlich arbeiten. ... und Nein ich habe nichts mit den Firmen zu tun.
