Sensor data collection from STM32 and SHT85 using Bluetooth Low Energy
https://www.electronics-lab.com/sensor-data-collection-from-stm32-and-sht85-using-bluetooth-low-energy/
A simple Bluetooth Low Energy project showing how to get sensor data from SHT85 which is connected to the STM32 Nucleo-144 using javascript. Requirements : A BleuIO dongle (https://www.bleuio.com/) An SHT85 sensor (https://sensirion.com/products/catalog/SHT85/) A board with an STM32 Microcontroller with a USB port. (A Nucleo-144 development board: NUCLEO-H743ZI2, was used to develop this example. (https://www.st.com/en/evaluation-tools/nucleo-h743zi.html) […]
SWAN – Low-Cost, Low-Power Embeddable STM32L4R5-based MCU from Blue Wireless

A handful of microcontrollers for IoT applications have hit the hardware ecosystem over the past years, allowing for easy development of embedded and standalone IoT-based systems. Most of these MCUs and processor chips, however, are expensive, power-consuming, and lack large memory and I/O expandability. The latest release from Blue Wireless seems to be an all-in-one […]
18650 LiPo Battery Manager for Remote Applications
https://www.electronics-lab.com/18650-lipo-battery-manager-for-remote-applications/
The 18650 LiPo battery manager comes with a fuel gauge and a dual-rail power supply. The dual-rail power provides a 5V rail along with a 3.3V rail dedicated to powering the microcontroller and the display ports of the system. It is termed as an “all-in-one single-cell LiPo battery manager” by Manuel Alfonso for its flexible […]
The Tiny Yet Powerful tArmDuino Features an STML071 MCU
https://www.electronics-lab.com/the-tiny-yet-powerful-tarmduino-features-an-stml071-mcu/
When you think of a tiny Arduino, all you expect is as many Arduino features as possible that can be large flash memory, programming connections, and obviously smaller board size. Developer Doctek designed a similar Arduino powered by ultra-low-power 32-bit MCU ARM Cortex-M0+ STM32L071KBU. Initially, the project used STM32L031G6 microprocessor but started facing several problems on the […]
2-channel USB thermocouple sensor using STM32
