The BM70 from Microchip Technology is a Bluetooth v4.2 Low-Energy module that supports a broad range of applications. It delivers up to 2.5x throughput improvement and more secure connections vs. Bluetooth 4.1 based products. The BM70 has a completely integrated Bluetooth software stack, and offers a shielded regulatory certified version with built-in antenna. It can independently maintain a low- power wireless connection, and the low-power usage and flexible power management that maximizes the modules lifetime in battery operated devices. The module supports UART/ I2C/ SPI interface and 12 bits ADC for 8CH input ports and battery voltage detection. It is available in a small, compact, surface mount module on the host PCB with the castellated pads, measuring 22 x 12 x 2.4 mm. It is targeted for applications such as wearable sports and fitness devices.
