With a smartphone or an MP3 player it’s easy to play audio files, but generally not at room strength or if you can, only in wretched quality. The Card Sound project makes it possible to fill the room with music and have excellent sound reproduction! This lightweight and compact player...

Similar to the earlier Lindenis V5 designed for AI video processing and 4K encoding, Lindenis has released another single-board computer that uses SoM and baseboard design for 4K camera applications called the Lindenis V536. The Lindenis V536 which runs on a new Allwinner dual...

What would you give for a battery, 5x the storage capacity of whatever you’re reading from? Well, the countdown to commercial availability for batteries of this type of capacity has already begun and it would be considerably cheaper than then currently available batteries. This...

Isabellenhütte has developed a new range of precision resistors in standard sizes with resistances ranging from 1 to 6 mOhm for applications that require small and low-ohmic shunts. In terms of their construction, the components are also less complex than the current...

NJR provides samples of a new adjustable shunt regulator NJM17431 with high precision and wide stable operation region that has been designed by latest process and analog circuit technology for many years. Because the NJM17431 has 0.8% accurate voltage reference and wide stable...

The MP23ABS1 is a compact, low-power microphone built with a capacitive sensing element and an IC interface. The sensing element, capable of detecting acoustic waves, is manufactured using a specialized silicon micromachining process to produce audio sensors. The MP23ABS1 has an...

This high current forward-reverse DC motor driver is built using STK681-332 IC from ON Semiconductor. The circuit can drive brushed DC Motor with up to 12 A peak current. The circuit requires 3 input signals: Enable for PWM input for speed control, IN1 and IN2 to change the motor...

This reference design enables a wearable, optimized saturation of peripheral capillary oxygen (SpO2) and multi-sensor, multi-wavelength optical heart rate monitor (HRM). It uses AFE4420 device, which is a single-chip, bio-sensing front end for photoplethysmography (PPG) measurements. It...
