u-bloxBMD-345-A-R
Overview
The BMD-345-A-R is a high-performance wireless module based on the Nordic Semiconductor nRF52840 SoC, featuring an integrated power amplifier and low noise amplifier (PA/LNA). It supports Bluetooth 5.0, Thread, and Zigbee, providing long-range connectivity via a U.FL connector for external antennas. With a 64MHz Arm Cortex-M4F core, 1MB of Flash, and 256kB of RAM, it provides significant resources for complex multiprotocol edge applications.
Why Choose This Part
The integrated PA/LNA significantly boosts link budget to -102dBm sensitivity and +18dBm output power, overcoming interference in dense RF environments. It simplifies design-in with a built-in USB 2.0 controller, high-speed SPI/UART interfaces, and 44 GPIOs, all while maintaining low sleep currents for battery-operated devices.
