The circuit presented here is a 300W off-line power factor correction (PFC) boost converter providing a nominal regulated output voltage of 375V @ 0.8A of load current. The project accommodates an input voltage range of 85V AC to 265VAC and uses average current mode control at a fixed...

Sunlight readable display may not be a new concept for most developers working on the Raspberry Pi single-board computers. For those who do not know how it works, then as the name suggests, a sunlight-readable display operates in direct sunlight or harsh light conditions. Those working...

Radxa launched the Rock Pi 4 Plus series of single-board computers with the Rockchip OP1 Processor, as an alternative to the Raspberry Pi. The new Rock Pi 4 Plus has been upgraded to a Rockchip OP1 processor, a powerful hexa-core ARM-based RK3399 SoC. Hence, it should be 11% faster than...

TDK Invensense's ICP-10111 is ideal for mobile phones, wearable fitness monitoring, drones, and battery-powered IoT TDK Invensense's ICP-10111 barometric pressure sensor is based on MEMS capacitive technology, which provides ultra-low noise at the lowest power, enabling excellent...

Addressing the need for streamlined power management solutions for energy harvesting hardware, e-peas has unveiled a new family of battery charger devices. While the company’s existing power management ICs (PMICs) offer direct power delivery to the application, as well as the...

This is an easy to construct dual-stage microphone pre-amplifier. The project can be used as a sound sensor or microphone pre-amplifier. The 1st op-amp pre-amplify the very low-level signal coming from the condenser microphone and 2nd op-amp provides more boost to the audio signal. The...

Rohde & Schwarz takes its successful R&S RTO family to the next level with the all-new and redesigned R&S RTO6 oscilloscope. Featuring an updated user interface on a larger, 15.6-inch Full HD touchscreen and straightforward workflows, it speeds up daily measurement tasks....
