The BBC has revealed the final design of the Micro Bit, a pocket-sized computer set to be given to about one million UK-based children in October. The device – which features a programmable array of red LED lights – includes two buttons and a built-in motion sensor that were not included in a prototype shown […]

Description The TPS65262 is a monolithic triple synchronous step-down (buck) converter with 3-A/1-A/1-A output current. A wide 4.5- to 18-V input supply voltage range encompasses the most intermediate bus voltage operating off 5-, 9-, 12-, or 15-V power bus. The converter, with constant frequency peak current mode, is designed to simplify its application while giving

Description The TUSB8041 is a four-port USB 3.0 hub. It provides simultaneous SuperSpeed USB and high-speed/full-speed connections on the upstream port and provides SuperSpeed USB, high-speed, full-speed, or low-speed connections on the downstream ports. When the upstream port is connected to an electrical environment that only supports high-speed or full-speed/low-speed connections, SuperSpeed USB connectivity is

This Design Idea demonstrates a simple way to generate a multiphase clock signal, the frequency of which can be varied with minimal change in phase shift(s). The phase shift of the second output can be tuned from near zero to 180° without affecting the frequency. The basic circuit uses a minimum of parts: one cap,

The story so far Welcome to the never ending saga of Andy and his reflow controllers. About a year ago I published a project writeup showing how I built a PID-based reflow controller. It featured a 640×360 graphical LCD from the Sony U5 Vivaz mobile phone and was all-surface mount. It worked well and continues

This is version 2.0 of the previously successful kickstarter project I launched last year. I have a ton of these PCB boards left over and it got me thinking. Why not find a P channel MOSFET with the same pinout and use it to control the direction of the motor also. I looked around and

Li-ion cells become more and more popular due to their capacity and reasonable prices. In this entry I will present how to build a simple li-ion battery charger based on MCP73831 chip. It’s a quite useful device for DYI projects,in addition its cost is only around 1,5 euro. The device uses USB port as a

Fujitsu has used an ultra small package for this memory part, which it presents as a solution for power-critical miniature applications in sensor and wearable markets. The 1Mbit SPI FRAM is in an 8-pin wafer level chip scale package (WL-CSP) which is an additional package variant to the existing product MB85RS1MT. In comparison to the
