This article covers Raytac MDBT50Q-CX Nordic nRF52840 ドングル開発キット Bluetooth Zigbee Thread用 (USB Type C.

Overview

The Raytac MDBT50Q-CX is a compact USB Type-C dongle built around the Nordic Semiconductor nRF52840 SoC. It supports Bluetooth 5.4, Zigbee, Thread, ANT+, and custom 2.4GHz RF protocols, making it a versatile wireless development tool. The unit comes with an open bootloader preloaded, allowing easy firmware updates and customization. With dimensions of just 26.2 x 15.1 x 6.8 mm and a weight of 2.99 g, it is ideal for prototyping IoT devices, wearables, and smart home gadgets. Note that this is a development kit and does not function as a plug-and-play Bluetooth adapter out of the box; you must load your own firmware first.

Connectivity & Compatibility

Interface: USB Type-C for connection to PCs, single-board computers, or embedded systems. Supported wireless protocols: Bluetooth 5.4 (BR/EDR/LE), IEEE 802.15.4 (Zigbee, Thread), ANT+, and 2.4 GHz proprietary RF. The nRF52840 integrates a 32-bit Arm Cortex-M4F CPU, 1 MB flash memory, and 256 kB RAM. Development can be done using Nordic SDK, Zephyr RTOS, or other compatible toolchains. The preloaded open bootloader simplifies flashing. The product carries certifications for FCC, IC, CE, TELEC, KC, SRRC, NCC, and RCM, ensuring compliance in many regions.

Product Info

As of June 2026, the MDBT50Q-CX is available on Japan for approximately ¥6,048 (tax included). Raytac is a recommended third-party module partner of Nordic Semiconductor. The dongle is positioned as an entry-to-mid-range development tool for prototyping. It includes the dongle only; no additional accessories are provided. Warranty details are handled by the seller. Given its bare-metal nature, it is not suited for users seeking an immediate Bluetooth solution without programming effort.

Best Use Cases

Embedded system engineers: Ideal for evaluating and prototyping IoT devices based on the nRF52 series. The open bootloader streamlines the firmware development cycle. Hobbyist developers: Experiment with multiple wireless protocols (BLE, Zigbee, Thread) on a single, affordable platform. Great for smart home DIY projects. * Researchers and educators: Use as a low-cost, multi-protocol wireless testbed for teaching wireless communication or conducting experiments.
