STM32 Wireless Innovation Design Contest

The STM32 Wireless Innovation Design Contest gives you the opportunity to showcase your creativity and design skills by creating exciting wireless applications using the powerful development and evaluation boards from STMicroelectronics. Whether you're passionate about IoT, robotics, gaming, home automation, or test and measurement, or AI, the possibilities are endless. €5,000 in cash prizes are up for grabs!

The Winners

After several exciting months of competition, during which dozens of innovative projects were submitted, the STM32 Wireless Innovation Design Contest has crowned its top three winners after an intense period of evaluation. As luck would have it, three Frenchmen won the podium places: Cédric Jiminez from Chambéry (first prize), Alain Romaszewski from Amélie-les-Bains (second prize), and Balthazar Deliers from Sequedin (third prize). Congratulations to all of them for their hard work!

The Boards


NUCLEO-WBA52CG is a Bluetooth® Low Energy wireless and ultra-low-power board embedding a powerful and ultra-low-power radio compliant with the Bluetooth® Low Energy SIG specification v5.3. The ARDUINO® Uno V3 connectivity support and the ST morpho headers allow the easy expansion of the functionality of the STM32 Nucleo open development platform with a wide choice of specialized shields.



The STM32WB5MM-DK Discovery kit is a demonstration and development platform for the STMicroelectronics STM32W5MMG module. This dual-core 32-bit Arm Cortex-M4/M0+ device integrates an ultra-low-power radio compliant with Bluetooth Low Energy (BLE) 5.2, 802.15.4 with Zigbee, Thread, and proprietary protocols.



The Nucleo-WL55JC board is an evaluation board for the STM32WL-series of microcontrollers, and in particular the STM32WL55. This so-called sub-GHz wireless microcontroller is based on a dual-core 32-bit ARM Cortex-M4/M0+ with a clock frequency of 48 MHz. It features ultra-low power consumption, an RF transceiver with a 150 MHz to 960 MHz frequency range, 256 KB of Flash memory and 64 KB of SRAM.



Libraries & Tools

Libraries and development tools

All STM32 products are supported by the STM32Cube platform. STM32Cube is ST’s original initiative to simplify and ease the life of the developer by reducing development effort, time, and cost. It provides developers with a hardware abstraction layer (HAL) and the low-layer (LL) APIs, a consistent set of middleware components, and many application examples that can be easily reused for custom application development.

STM32Cube includes STM32CubeMX, a graphical software configuration tool that uses graphical wizards to help the developer generate C initialization code.
A suitable toolchain for developing applications for the three boards presented in this article (and many more) is, of course, STM32CubeIDE from STMicroelectronics themselves, which is free of charge. Keil’s MDK-ARM and IAR’s Embedded Workbench can be used too, at the developer’s expense.
The stm32duino boards package for the Arduino IDE supports the STM32WB5MM-DK board. It also knows about the WL55JC, but without LoRa support. The WBA52CG board is not (yet) supported.
Both the STM32WB5MM-DK and WL55JC boards are also compatible with ARM’s mbed OS, so that is another avenue to explore.
