BMD-300

Powerful. Efficient. Connected.

Status: Production

The BMD-300 is based on the advanced nRF52832 BLE SoC from Nordic Semiconductor, bringing the latest Bluetooth connectivity coupled with class leading performance. It combines a Bluetooth 5 compliant 2.4GHz transceiver, 64MHz ARM® Cortex™ M4F CPU, 512kB of flash memory, 64kB RAM options, a suite of analog and digital peripherals, and a DC-DC converter with advanced power management into a miniaturized package. The BMD-300 enables tomorrow’s most demanding IoT and wearable applications.

Available with a high performance integrated antenna (BMD-300) or a U.FL connector for use with an external antenna (BMD-301).
