The nRF52840-MDK is a versatile, easy-to-use IoT hardware platform for Bluetooth 5, Bluetooth Mesh, Thread, IEEE 802.15.4, ANT and 2.4GHz proprietary applications using the nRF52840 SoC.


The development kit comes with a fully integrated debugger (also known as DAPLink) that provides USB drag-and-drop programming, USB Virtual COM port and CMSIS-DAP interface.


The kit contains a Microchip USB 2.0 Hi-Speed hub controller with two downstream ports: one for DAPLink interface and one for nRF52840 USB device controller. The kit also features ultra-low power 64-Mb QSPI FLASH memory, programmable user button, RGB LED, up to 24 GPIOs, antenna selection for custom applications.


It supports the standard Nordic Software Development Tool-chain using GCC, Keil and IAR. It can also be used to play with many popular frameworks, such as nRF5 SDK, nRF5 SDK for Mesh, OpenThread, ZigBee 3.0, Mbed OS 5, Zephyr, Mynewt, Web Bluetooth, iBeacon, Eddystone, and more.

Questions and Answers

There are no document that explains nRF52840-MDK development using Keil. Also the makerdiary examples for nrf5-sdk are very limited. Can anyone help me setting up Keil5 for nRF52840-MDK? I want to nrf5-sdk examples specifically BLE peripheral example.

Got two nRF52840-MDK kits. Tried MDK#1: green LED OK, serial OK, but not found on nRF Connect. Tried 2nd one, this time with nRF Connect up and scanning. When I plugged in MDK#2, it showed up on nRF Connect. I connected, then the MDK went away -- not seen on nRF Connect, on Bluefruit app, etc. (Did I smell smoke?..) Flashed other sample apps via copy to DAPLINK drive.LED, serial work, but no joy on RF. Did I fry the radios on my MDKs simply by powering them up?

Hi there, Very sorry for the late reply. Have you solved your problem? Could you tell me more details about your phone and system. It seems that you should clear the GATT cache on mobile device. Pls let me know if you have any concerns.
