Quectel HCM511S MCU Bluetooth module

Quectel Wireless Solutions has launched the HCM511S MCU Bluetooth module for compact connected devices such as digital keys, portable devices and battery-operated motion sensors. Utilising Bluetooth Low Energy 5.4, the module accommodates an ARM Cortex-M33 processor and features built-in 32 KB RAM and either 352 or 512 KB flash memory.

The module also features enhanced receiver sensitivity and a maximum transmit power of +6 dBm to facilitate long-distance transmission. Measuring 16.6 x 11.2 x 2.1 mm, the module is in the ultra-compact LCC form factor in order to optimise size for end products. Suitable applications for the module include sports and fitness devices, PC peripherals and accessories, healthcare applications including blood pressure and glucose metering, indoor navigation, digital key, connected lighting control and smart home and smart building applications.

The module also offers the option of support for Bluetooth mesh network low-power nodes. This enables increased network scalability and node counts over mesh topology, enabling greater device density. The module offers up to 18 GPIOs which can be multiplexed for various interfaces including ADC, USART, I2C, I2S, SPI and PWM to increase developer design options.

Connecting via a PCB Bluetooth antenna, the module can operate in industrial-grade operating temperature ranges of -40 to +85°C and weighs 0.57 g. The module is also certified for use in Europe, America, Canada, China, Australia and New Zealand. It has also been certified by the Bluetooth Special Interest Group.

The module supports Secure Vault, a secure engine for a higher level of IoT security.
