- BDE-BDM209B(Bluetooth 5.1 Dual-Mode Based on STM32L431 and CC2564C)
- General Description
BDE-BDM209B is a Bluetooth 5.1 Basic Rate (BR), Enhanced Data Rate (EDR) and Low Energy (LE) Dual-Mode module.
The module offers a unique combination of Bluetooth Classic and Bluetooth Low Energy radio (CC2564C) from Texas Instruments (TI) and an ultra-low-power Arm® Cortex®-M4 32-bit MCU (STM32L431). It integrates all required external components, including level shifters, clocks, power supply, band-pass filter, and antenna, at an affordable cost.
The module provides best-in-class RF performance with transmit power and receive sensitivity that offer twice the range and higher throughput compared to other Bluetooth Low Energy-only solutions. The power management hardware and software algorithms deliver significant power savings in all commonly used Bluetooth BR/EDR and Low Energy modes of operation.
The module is pre-certified with FCC, ISED, and CE (In-progress), and comes with certified and royalty-free Dual-mode Bluetooth 5.1 protocol stack software. It provides complete Bluetooth BR/EDR and Bluetooth Low Energy sample applications, reducing design effort and ensuring a faster time to market.
