- BDE-BLEM205(Bluetooth 5.0 Low Energy Based on CC2642R)
-
- General Description
BDE-BLEM205 is a Bluetooth 5.2 single-mode compliant Bluetooth low energy module targeted at low power sensors and PC/Phone accessories.
BDE-BLEM205 highly integrates Bluetooth Low Energy radio, stack, profile and applications in a SoC, without the need of using an external MCU. The module also offers flexible hardware interfaces for the sensor application. It supports 2 Mbps and PHY-coded which are the new added features from BT5.0. The module is Bluetooth, FCC, ISED and CE-RED certified.
It enables ultra-low power connectivity and data transfer for the applications that are sensitive to power consumption, size and cost.
