This happy state of never encountering anything but 5V logic as a hobbyist has not persisted. In recent decades the demands of higher speed and lower power ... the circuits we use when ...

To make everything work, a load resistor on the 5V circuit makes the power supply think it’s hooked up to a motherboard. It’s all wrapped up in a neat slant-sided 3D-printed case that fits ...

if you know you will only power rupture with a 5v supply then the regulator part of the circuit (c7, c8, r1, r2, u1, sw9) can be omitted - just connect the middle and left pins on the sw9 footprint ...

PowerBoost 1000C is the perfect power supply for your portable project! With a built-in load-sharing battery charger circuit, you'll be able to keep ... and convert the battery output to 5.2V DC for ...
