Do PCI 2.1/2.2 slots support both 5v and 3.3v signaling?<BR><BR>I was under the assumption that all conventional PCI devices were 5v only, but am now extremely confused at which specs support which ...
Today I got a multimeter (nothing fancy, precision is +/-0.5% for DC current to tweak my lines (Antec Truecontrol).<BR><BR>Findings:<BR>- motherboard measurments are generally unreliable, for instance ...
[Kevin Darrah] wanted to make a simple 3.3V regulator without using an integrated circuit. He wound up using two common NPN transistors and 4 1K resistors. The circuit isn’t going to beat out a cheap ...
When Arduino debuted, most sensors and other interfacing devices ran on 5 volts. This tutorial shows how to hack your 5 volt Arduino board to run on 3.3 volts. It is a simple procedure involving ...
A Raspberry Pi Zero is down to a price and size where it’s just begging to be integrated into your projects. Unless, that is, if your project involves a lot of 5 V equipment. Then it’s just begging to ...
