Description

The BM70 Bluetooth Low Energy module is designed for easy implementation into a broad range of applications. It delivers up to 2.5x throughput improvement and more secure connections vs. Bluetooth 4.1 based products. Developers can easily interface to the device via a standard UART interface, available on most Microcontrollers and Processors. The BM70 has a completely integrated Bluetooth software stack, and offers a shielded regulatory certified version with built-in antenna. Developers are freed from the complexities of Bluetooth Software and RF development and can simply utilize the BM70 as a wireline replacement. Perfect for IoT (Internet of Things) applications, when interfaced to a BLE enabled smartphone or Bluetooth Internet Gateway, applications can be monitored, controlled and updated from anywhere in the world. The Microchip Bluetooth Data (MBD) mobile app is available to speed up development for both [Android](https://play.google.com/store/apps/details?id=com.microchip.bluetooth.data) and [iOS](https://apps.apple.com/us/app/microchip-bluetooth-data/id1319166097).
