USB Dongle
Bluetooth® 5 Low Energy (LE), Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT
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.
