The MDBT50Q-1M is a compact Bluetooth Low Energy module based on the Nordic nRF52840 Cortex-M4 processor. It integrates the BLE radio, native USB support, and a chip antenna into a small, pre-certified package — ready to drop into your custom PCB design.

With generous flash and SRAM, plus a wide range of peripherals, the nRF52840 is a capable SoC for BLE applications. The module comes with FCC, CE, and TELEC certifications. Note that it uses under-pad connections (not castellated), so reflow soldering with a stencil and hot air or reflow oven is required.
