If you're developing a wrist watch, a small light-following robot, or a portable weather station with Arduino, one of the best boards you can use is the Nano, and for good reason. It's pretty compact, ...

Over the years, we’ve seen some modern microcontrollers turn out to be 5V-tolerant – now, RP2040 joins the crowd. Half a year ago, when we covered an ISA card based on a Pi Pico, [Eben Upton] left a ...

This circuit is a very simple voltage monitoring device for +5V VCC supply lines. It can be used to monitor the power supply of a microcontroller (uC) by indicating when the supply level raises above ...

This circuit is a small +5V power supply, which is useful when experimenting with digital electronics. Small inexpensive wall transformers with variable output voltage are available from any ...

The Raspberry Pi 5 used this time was sent directly to the GIGAZINE editorial department from the Raspberry Pi Foundation and has not received technical standards compliance certification. Therefore, ...

It seems to me that the -5V and -12V lines are pretty much obsolete and just thrown in for compatibility reasons. As a matter of fact the SFX power supply standard drops the -5V entirely but keeps the ...
