Electronics used to be all 5v. You can't do that anymore. It's all 3.3v. Because of woke.

@foone for now. We'll be doing level shifters to 2.1v or 0.8v at some point soon I'm sure of it.(especially as fpga's get more common in the maker space.)

@foone It's all a scam by Big Coulomb to sell you less volts for more amps. >:(

@foone When I grew up, we used the 4,5V things for our projects, 9V was for the dangerous stuff. This is all too modern for me!

@foone do you know why 5v got chosen in the first place?

@ticktok at least those voltages have the common sense to stay in their lane! Behind level shifters!No one is making a microcontroller where the whole thing has 0.8v IO. Yet.

@foone it's older: 7400s (which were originally TTL) require 5V, while 4000s have a much wider supply voltage range (apparently 3-15V).

@foone The Altair I cut my teeth on had an 8080 that needed +5V, -5V and +12V. Add -12V for the RS-232 interface and you had the full complement. None of this woke 0.8V FPGA nonsense!

@foone All this +V normativity these days. Back in my day if you wanted to tie Vcc to ground and Vee to -5.2V, you just did it, and let everyone else worry about their own rise times.

@fooneNah. It's just all the greedy capitalists. They need to promote consumption by making our good old 5v tools obsolete.

@Li yeah that's part of the joke! I can be annoyed that most microcontrollers are 3.3v now but it's not like 5v is impossible to find or level shifting isn't easy.I'd just be complaining that the thing I want is no longer the default, but just another option.Like the people who get mad they have to press "1" for English on a phone tree
