HopeRF HM-BT22014L Bluetooth 5.2 Module w/ ARM Cortex-M33

Description

The HM-BT22014L is a fully integrated Bluetooth Low Energy 5.2 data transmission module designed for seamless wireless connectivity in embedded systems. At its core is an ARM Cortex-M33 32-bit processor capable of operating at up to 76.8MHz, paired with an embedded 2.4GHz RF transceiver and an on-board PCB antenna. This combination provides a complete wireless subsystem, enabling the module to function either as a simple BLE radio controlled via UART AT commands or as a standalone microcontroller for more integrated applications.

The module’s architecture is optimized for low-power IoT deployments, featuring multiple power-saving modes including a deep sleep state drawing only 1.4µA. Its RF performance includes a transmit power configurable up to +6dBm and a receiver sensitivity of -98.9dBm at 1Mbps GFSK, ensuring reliable communication links. The integrated protocol stack supports BLE versions 4.x through 5.2, making it compatible with a wide range of smartphones, tablets, and gateways.
