Small Size BLE 5.1 Bluetooth Module Low Power Consumption for Health and Medical Devices

RHA-BT107Z is a BLE 5.1 module independently developed by IoTRHA. It features a small size, ultra-low power consumption, supports both master and slave modes, multiple connections, and a data transfer rate of up to 60KB/s. It is customizable and can be applied in smart home, health and medical, automotive electronics, and other fields.

RHA-BT107Z is a high-performance BLE 5.1 SoC communication module, primarily used in networking, data transmission, and positioning within the BLE domain. It is a high-performance, low-power multi-protocol 2.4GHz SoC communication module, supporting low-power Bluetooth 5.1 and DetMesh. It supports star networks, mesh networks, and dynamic ad-hoc networks. When embedded with the DetMesh network protocol, each RHA-BT107Z supports master, slave, or master-slave modes, enabling flexible network joining and leaving, and supports multi-protocol operation with time-division and frequency-division multiplexing across different network layers.

RHA-BT107Z has extremely low active RF and MCU current and low power modes, supporting deep sleep and shutdown modes with various wake-up methods. These features ensure excellent battery life, making it suitable for small button battery power supply and energy-harvesting applications.

The BLE 5.1 Bluetooth Module includes a 32-bit high-performance microcontroller unit and a 12-bit high-precision SAR ADC, integrating a complete RF system and on-chip DC/DC converter. It has a built-in temperature sensor and rich peripheral resources, including DMA, watchdog timer, system tick timer, and various communication interfaces. The chip also has a floating-point unit for fast floating-point calculations.
