> A small, low-cost USB Dongle designed with nRF52840

## Description

nRF52840 MDK USB Dongle is a small and low-cost development platform enabled by the nRF52840 multiprotocol SoC in a convenient USB Dongle form factor.

The design features a programmable user button, RGB LED, up to 12 GPIOs and 2.4G Chip antenna on board. It can be used as a low-cost Bluetooth5/Thread/802.15.4/ANT/2.4GHz multiprotocol node or development board. Alternatively the USB Dongle can be used as a Network Co-Processor(NCP) with a simple connection to a PC or other USB enabled device.

It's shipped with the UF2 Bootloader, supports [nRF Connect SDK][ncs-guide], which integrates the Zephyr RTOS, protocol stacks, samples, hardware drivers and much more. The dongle can work as a [Bluetooth Low Energy][ble-sniffer] and [IEEE 802.15.4][nrf802154-sniffer] packet sniffer with Wireshark, and has PCBA and w/Case options to meet various scenarios.
