Amphenol Advanced Sensors SM-UART-04L Laser Dust Sensor offers a 5.5V rating, a 100mA current consumption, and a 3.3V output performance. This sensor detects dust particle concentrations in the air by using an optical sensing method. The SM-UART-04L sensor finds small particles such as...

DIABNEXT’s ‘CLIPSULIN’ device attaches to insulin pens and employs Nordic’s nRF52832 SoC to wirelessly send recorded insulin injection data via Bluetooth LE or NFC. Nordic Semiconductor today announces that Taiwan-based DIABNEXT, a healthcare services company, has selected...

A team of researchers from Germany and Argentina have devised an ultra-thin planar Hall effect (PHE) sensor capable of detecting very faint magnetic fields even when flexed or wrapped around a wire. by Julien Happich @ www.eenewsembedded.com In a paper titled “Highly compliant planar...

Sipeed MAix: AI at the edge AI is pervasive today, from consumer to enterprise applications. With the explosive growth of connected devices, combined with a demand for privacy/confidentiality, low latency and bandwidth constraints, AI models trained in the cloud increasingly need to be...

Jesus Echavarria @ jechavarria.com has build a 4 in 1 USB Serial converter based on MCP2221A. This board is mainly a USB hub with 4 USB to serial converters. Is like the typical USB to TTL adapter but with one USB port you get up to 4 serial ports. Levels of every converter are...

Pyboard D-series (aka Pyboard D, or just PyBD) board was introduced during the Micropython presentation at FOSDEM 2019 and it's build around a faster STM32F7 Cortex-M7 MCU, with 512Kb of RAM, and 2Mb of Flash, as well as built-in WiFi and Bluetooth connectivity. It also features a pair...

The project published here is a high-performance Unipolar stepper motor driver that offers PWM controlled high current output. An Arduino board and the project published here can be combined to create a good Unipolar stepper motor driver with micro-stepping, supply 36v DC and load...

The project described here is small 5W LED driver, that can be used in variety of applications by changing the mcu code. The example code provided is a simple digital toggle switch using two tactile switches. One switch is used for power ON and the other for OFF. The on board small...
