Added to your shopping cart

The nRF52840 Dongle is a small, low-cost USB dongle that supports Bluetooth 5, Bluetooth mesh, Thread, ZigBee, 802.15.4, ANT and 2.4 GHz proprietary protocols. 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. For other use cases please do note that there is no debug support on the Dongle, only support for programming the device and communicating through USB.

It is supported by most of the nRF Connect for Desktop apps and will automatically be programmed if needed. In addition custom applications can be compiled and downloaded to the Dongle. It has a user programmable RGB LED, a green LED, a user programmable button as well as 15 GPIO accessible from castellated solder points along the edge. Example applications are available in the nRF5 SDK under the board name PCA10059.

The nRF52840 Dongle is supported by nRF Connect for Desktop as well as programming through nRFUtil.

    There are pads for the standard 10-pin ARM debug header on the bottom, so you can program/debug using the Nordic SDK and Segger debugger. The nRF52840's 73 pin package can be difficult to solder by hand( i.e., impossible). With the castellated pads, this is a very effective way to get the nRF52840 on a PCB.

    I know sparkfun has to make money but with shipping costs and the $2 price increase. I don't see why you wouldn't buy from this DigiKey.

      One reason is if your local, there is no shipping (i.e. local pickup). Another is to support SparkFun, and their library and tutorial efforts.

Perfect for experimenting with BLE beacons

With Nordic software this can be a spectrum analyzer, beacon, beacon scanner, development tool for other beacons (to download software over-the-air), lots of other uses. It isn't best for development of software to run on the on-board chip, though I gather that is possible. I mainly used the Connect tool, monitoring and connecting to beacons.
