STMicroelectronics looks to boost IoT design productivity STMicroelectronics is now offering a solution to accelerate the market introduction of Bluetooth LE and 802.15.4 based IoT devices with a miniature, ready-to-use STM32 wireless microcontroller (MCU) module. The 7mm x 11.3mm STM32WB5MMG module has been designed to let product teams build connected devices without needing wireless-design skills. Made to enable low-cost PCB technology requiring a minimal number of layers, it integrates everything up to the antenna. Users can also leverage the tools, design wizards, radio stacks, and turnkey software libraries of STâs STM32Cube MCU development ecosystem, available free of charge, to complete the project quickly and efficiently.
