A small and low-cost nRF52840 Micro Development Kit in USB Dongle Form Factor
The 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/Tread/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.
