BM70 Bluetooth Low Energy (BLE) Modules

The BM70 BLE module from Microchip Technology is designed for easy implementation into a broad range of applications. It delivers up to 2.5x throughput improvement and more secure connections versus Bluetooth 4.1 based products. Developers can easily interface to the device via standard UART, 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.

The Microchip Bluetooth Data (MBD) mobile app is available to speed up development for both Android and iOS. Microchip's complimentary and confidential wireless check online design review service is available for customers who have selected Microchip’s products for their application design-in. The BM70 is perfect for Internet of Things (IoT) applications when interfaced to a BLE-enabled smartphone or Bluetooth Internet Gateway; applications can be monitored, controlled, and updated from anywhere in the world.
