Ideal for wearables: With the REX128128B, Raystar Optronics offers a 128×128-pixel CoG Circular OLED display as an interesting alternative to TFT or LCD, among others. The round 1.18“ POLED is particularly thin at 2.05 mm and impresses with excellent viewing angle properties and a...

The project described here is a 3-Phase isolated Hall-effect current sense amplifier with +/-600-V working voltage range. The current sensor senses magnetic flux generated from current passing through the lead frame at common-mode voltages 0 to 600V DC and provides proportional output...

This is a precision, low power, and easy-to-use oscillator that provides multiphase outputs. The output frequency of the project is set to 250Khz, with 40% spread spectrum. The oscillator frequency can be set by resistor R1, and the spread spectrum can be changed using R3. The master...

The 63000 series programmable DC electronic loads are reliable, precision instruments primarily designed to test switching power supplies, A/D power supplies, power electronic components, adapters, 3C batteries and chargers. Its maximum 350W rated power makes it suitable for testing...

WEBS-21G0 Is Rugged, Compact, Fan-less and Ideal for Digital Signage, Medical Equipment, IoT Edge, Communication and Industrial Automation and Control Applications American Portwell Technology, Inc., a world-leading innovator for Industrial PC (IPC) and embedded computing solutions,...

Vesper of Massachusetts is claiming high fidelity for a MEMs piezo microphone that picks up the vibration of the user’s voice through the skull. Inside are the mems, an amplifier, and a power regulator. Called VA1200, the company describes it as “the world’s first analogue...

Yet another development featuring Espressif Systems’ powerful ESP32-S2 SoC. Unexpected Maker has launched the TinyS2 ESP32-S2 development board. We have seen many boards with this SoC. This includes Olimax’s USB development board and Adafruit’s Wi-fi feather board harnessing the...

Sometime in November last year, we wrote about two fanless mini PCs that were introduced by T-chip Technology’s Firefly: the Station P1 and M1 geek computers, powered by the Rockchip RK3399 hexa-core and RK3328 quad-core processors respectively. We are back now to talk about a...
