nRF52840 Bluetooth Low Energy Module with USB – MDBT50Q-1MV2

If you have a custom PCB design and you’d like to add a little Bluetooth Low Energy, this module is ultra-compact and easy to use. It contains a Nordic nRF52840 Cortex M4 chip that comes integrated with BLE radio, USB as well as most of the supporting circuitry, and even a chip antenna. The whole thing is in a tin and comes with FCC, CE, and TELEC certifications.

This chip is quite a beast, with a ton of FLASH, SRAM, peripherals, and best of all … native USB support! No need for an external USB-serial converter chip. However, given that it uses underpads instead of castellated pads, you cannot hand-solder it, you’ll need a stencil and hot air or a reflow oven.

Please note! The module comes with a blank chip – this is for people who are comfortable programming the chips themselves with a J-Link programmer and the Nordic SDK. We don’t provide any firmware to go along with it!

This is the same module we use for the Adafruit nRF52840 Feather
