nRF52840 Dongle — compact USB target hardware designed for use with Connect for Desktop Key benefits Inexpensive, practical development and test tool: low cost makes it easy to deploy multiple units for development, QA, and field testing without large expense. Broad short-range wireless support: built on the nRF52840 SoC and supports Bluetooth low-power, Bluetooth, Thread, ZigBee, 802.15.4, ANT and 2.4 GHz proprietary protocols, covering the short-range standards used by Nordic devices. Ready for Connect for Desktop: specifically designed to function as the wireless hardware device for Connect for Desktop, enabling straightforward integration with desktop development and debugging workflows. Compact USB form factor: small, plug-in dongle ideal for desktop use, labs, or portable test setups. Compatibility and function Works with Connect for Desktop as the target wireless adapter for development, testing, and interaction with Nordic-based devices. Supports multiple radio protocols on the nRF52840 SoC, enabling cross-protocol development and interoperability testing without changing hardware. USB dongle design provides easy connection to a PC for firmware flashing, monitoring, and protocol analysis. Practical attributes Function: development, testing, debugging, and prototyping of short-range wireless applications. Compatibility: Connect for Desktop and Nordic device wireless standards (Bluetooth low-power, Bluetooth, Thread, ZigBee, 802.15.4, ANT, 2.4 GHz proprietary). Size/format: compact USB dongle for convenient desktop and portable use. Performance: leverages the nRF52840 SoC to support multi-protocol 2.4 GHz wireless applications. Example use scenarios 1) Firmware development and verification: plug the dongle into a PC running Connect for Desktop to flash, test, and validate firmware on devices implementing BLE, Thread, ZigBee, or other 2.4 GHz protocols. 2) Protocol analysis and debugging: use the dongle with Connect for Desktop to capture, monitor, and troubleshoot wireless traffic between Nordic devices during development or QA. 3) Rapid IoT prototyping: attach sensors or peripherals to prototype boards and use the dongle as the USB-connected radio to evaluate interoperability across Bluetooth, Thread, ZigBee, or proprietary 2.4 GHz links. The nRF52840 Dongle delivers a cost-effective, compact, and protocol-flexible hardware option for developers and testers working with Nordic short-range wireless technologies and Connect for Desktop.
