STMicroelectronics' STM32WB5MMG Wireless Module Supports Bluetooth LE 5.0, Zigbee 3.0, and More

STMicroelectronics has introduced a compact, ready-to-use STM32 wireless microcontroller module for Bluetooth LE and 802.15.4-based IoT devices: the STM32WB5MMG, designed for smart home, building, and factory applications.

“Our first STM32-based wireless module simplifies technical challenges and extends exciting opportunities for smart connected devices,” said Ricardo de Sa Earp, STMicroelectronics' Group Vice President, Microcontroller Division General Manager. “A complete ready-to-use subsystem in a single package, the STM32WB5MMG assures excellent radio performance out of the box and comes as a certified solution according to Bluetooth, Zigbee, and OpenThread specifications.”

The STM32WB5MMG module, which measures 7mm x 11.3mm, is an ultra-low-power module featuring a dual-core Arm Cortex-M4 MCU clocked up to 64MHz frequency and a Cortex-M0+ at 32MHz. Additionally, the module supports the company's unconventional concurrent dual-protocol mode. This enables any protocol based on IEEE 802.15.4 radio technology (Zigbee 3.0 and OpenThread) to directly connect to a Bluetooth Low Energy device.

Moreover, the STM32WB5MMG acts as a solution to common cost and design complexities. To help overcome these, STMicroelectronics also plans to release an STM32WB55MMG-DK board that will have several sensors, an LCD, external memory, and more.

The bulk production of the module is now available (but currently "out of stock") priced at $5.66 for orders of 10,000. Additional information can be found on STMicroelectronics' product page and in their blog post here.
