The nRF52840 Dongle is a small, low-cost USB dongle for Bluetooth® Low
Energy (LE), Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz
proprietary applications using the nRF52840 SoC. The dongle is the perfect
target hardware for use with nRF Connect for Desktop as it is low-cost but
still support all the short range wireless standards used with Nordic devices.
The dongle has been designed to be used as a wireless HW device together
with nRF Connect for Desktop.
It can also be used to develop code for the nRF52840 SoC mounted on the
dongle. Programming is supported through a USB enabled bootloader.
Connectors for external debuggers are available.
The dongle is supported by most of the nRF Connect for Desktop apps and
will automatically be programmed if needed. It is the number one target for
coming nRF Connect apps. In addition, custom applications can be made
and downloaded to the dongle. It has a user programable RGB LED, a green
LED, a user programmable button as well as 15 GPIO accessible from
castellated solder points along the edge.
