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.\n\nIt'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.\n\n![product hero](./docs/assets/images/nrf52840dongle-hero.png)\n\n## Key Features\n\n* Nordic Semiconductor nRF52840 SoC\n\n    - 64 MHz Arm® Cortex-M4 with FPU\n    - 1 MB Flash + 256 KB RAM\n    - Bluetooth LE, Bluetooth mesh, Thread, Zigbee, 802.15.4, ANT and 2.4 GHz proprietary\n    - Arm TrustZone® Cryptocell 310 Security Subsystem\n    - 2.4 GHz Transceiver with +8 dBm TX Power\n    - GPIO, UART, SPI, TWI(I2C), PDM, I2S, QSPI, PWM, QDEC, 12-bit ADC support\n    - Integrated USB 2.0 Full-speed Controller\n    - Integrated NFC-A Tag\n\n* Arm Serial Wire Debug (SWD) port via edge pins\n* Up to 12 GPIOs available via edge pins\n* User programmable Button and RGB LED\n* On-board 2.4G chip antenna\n* 3.3V regulator with 1A peak current output\n* VBUS \u0026 VIN Power-Path Management\n* Convenient USB dongle form factor\n* Breadboard-friendly with dual 10-Pin headers\n* Measures 1.65\" x 0.7\" x 0.15\" (42mm x 17.78mm x 3.75mm) without headers soldered in\n* w/Case option available to provide protection and ease of use\n* Shipped with UF2 Bootloader supporting Drag-and-drop programming over USB drive\n* Built on open source, supporting nRF Connect SDK, Zephyr RTOS, Google's OpenSK, etc.\n\n## Hardware diagram\n\nThe following figure illustrates the nRF52840 MDK USB Dongle hardware diagram.\n\n[![](./docs/assets/images/nrf52840-mdk-usb-dongle-pinout.png)][pinout-diagram]\n\n## Mechanical dimensions\n\nnRF52840 MDK USB Dongle PCBA is a single sided 42mm x 17.78mm (1.65\" x 0.7\") 2.0mm thick PCB with a USB-A port and dual castellated/through-hole pins. nRF52840 MDK USB Dongle w/Case includes a high-quality plastic case in 50.8mm x 21.1mm (2.0\" x 0.83\") 7.6mm thick.\n\n![](./docs/assets/images/mechanical_specs.png)\n\n## Documentation\n\nWe offer an extensive set of documentation such as getting started guides and developer guides, which can help you save big by reducing development effort.\n\n* [nRF52840 MDK USB Dongle Wiki][wiki]\n* [nRF52840 MDK USB Dongle Product Brief][product-brief]\n* [nRF52840 MDK USB Dongle Quick Start Guide][quickstart]\n* [How to program the nRF52840 MDK USB Dongle][programming]\n* [Develop with nRF Connect SDK \u0026 Zephyr RTOS][ncs-guide]\n* [nRF Sniffer for Bluetooth LE][ble-sniffer]\n* [nRF Sniffer for 802.15.4][nrf802154-sniffer]\n* [OpenSK FIDO2 Authenticator Guide][opensk]\n\n## Where to buy\n\n| Official Store | Buy Now |\n|:--------------:|:-------:|\n| \u003ca href=\"https://makerdiary.com\"\u003e\u003cimg alt=\"makerdiary store\" display=\"inline\" src=\"./docs/assets/images/makerdiary-store.png\" width=\"160\"\u003e\u003c/a\u003e | [![PCBA](https://img.shields.io/badge/PCBA-AC2E45)](https://makerdiary.com/products/nrf52840-mdk-usb-dongle) [![w/Case](https://img.shields.io/badge/w%2FCase-AC452E)](https://makerdiary.com/products/nrf52840-mdk-usb-dongle-w-case) |\n| \u003ca href=\"https://www.tindie.com/stores/makerdiary/\"\u003e\u003cimg alt=\"Tindie\" display=\"inline\" src=\"./docs/assets/images/tindie-store.png\" width=\"80\"\u003e\u003c/a\u003e | [![PCBA](https://img.shields.io/badge/PCBA-AC2E45)](https://www.tindie.com/products/makerdiary/nrf52840-micro-dev-kit-usb-dongle) [![w/Case](https://img.shields.io/badge/w%2FCase-AC452E)](https://www.tindie.com/products/makerdiary/nrf52840-mdk-usb-dongle-w-case/) |\n| \u003ca href=\"https://zaowubang.taobao.com\"\u003e\u003cimg alt=\"Taobao\" display=\"inline\" src=\"./docs/assets/images/taobao-store.png\" width=\"80\"\u003e\u003c/a\u003e | [![PCBA](https://img.shields.io/badge/PCBA-AC2E45)](https://item.taobao.com/item.htm?spm=a1z10.1-c.w4004-2992523845.4.7e39796cobENAV\u0026id=578378054977) [![w/Case](https://img.shields.io/badge/w%2FCase-AC452E)](https://item.taobao.com/item.htm?spm=a1z10.3-c.w4002-2992521588.13.629e3f9aZAbOdL\u0026id=597968842403) |\n\n| Approved Distributor | Buy Now |\n|:--------------:|:-------:|\n| \u003cimg alt=\"seeedstudio\" display=\"inline\" src=\"./docs/assets/images/amazon_logo.png\" width=\"120\"\u003e | [![PCBA](https://img.shields.io/badge/PCBA-AC2E45)](https://www.amazon.com/gp/product/B07MJ12XLG) [![w/Case](https://img.shields.io/badge/w/Case-AC452E)](https://www.amazon.com/GeeekPi-nRF52840-MDK-Dongle-Case/dp/B07TSJHTSY) |\n| \u003cimg alt=\"seeedstudio\" display=\"inline\" src=\"./docs/assets/images/seeedstudio.png\" width=\"160\"\u003e | [![PCBA](https://img.shields.io/badge/PCBA-AC2E45)](https://www.seeedstudio.com/nRF52840-MDK-USB-Dongle-p-3184.html) [![w/Case](https://img.shields.io/badge/w/Case-AC452E)](https://www.seeedstudio.com/nRF52840-MDK-USB-Dongle-w-Case-p-4094.html) |\n\n## Community Support\n\nCommunity support is provided via [GitHub Discussions][discussions].
