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 nRF52840-MDK kit contains a Microchip USB 2.0 Hi-Speed hub controller with two downstream ports: one for the DAPLink interface and one for the 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.
Nordic nRF52840 System-on-Chip
The nRF52840 SoC is built around a 32-bit ARM® Cortex®-M4F processor optimized for ultra-low power operation, combining Bluetooth 5, Bluetooth Mesh, Thread, IEEE 802.15.4, ANT and 2.4GHz proprietary. It is also featured with on-chip NFC-A tag and on-chip USB 2.0 (Full speed) controller. The SoC is developed with 1 MB FLASH and 256 kB RAM.
