Re: Can't get GPIO (or 5V pin) functioning

I have 90 degree male header on one of my Pi Zero's, soldered on the same way yours is. When plugged into a Hat or pHat the pinout is correct and it works as intended. I also have a female header on another Pi. It's soldered on the other way though, on the back side of the board. It points down, not...

Re: Can't get GPIO (or 5V pin) functioning

What he said, plug the ribbon cable in between your Pi and the cobbler, and see if things get sorted out. Pin 1 on your Pi isn't going to Pin 1 on the cobbler. To do what you want I think the header has to be soldered so the pins are on the opposite side of the Pi.

Re: Pi Zero with headers

You can buy kits with the headers included, but not soldered on. There is more than just the header in the kit though, and you still can't buy more than one. Not that I've seen. Well yes, and that's the problem; that's not what is wanted by many people. In fact it seems to fail on all measures on w...

Turn the LED around, reverse the leads and try again. An LED will only conduct in one direction, reverse bias it and it won't work.

Re: Pi Zero with headers

Pimoroni are charging you £3.80 for someone to stick the header in and run it through a solder bath. If your handy with a soldering iron, that deal is likely not for you. But going by some of the botched solder jobs I've seen, it will appeal to those that don't know how to solder. And don't get me ...

Re: Raspberry pi zero w doubts

LIPO batteries are ~3.7 volts. You need 5V to run a PI. Trying to run a Pi directly from a LIPO battery is not a good idea, it won't work. The power boost boosts the LIPO's voltage to 5V. It will also maintain the voltage at 5V as the battery runs down. If you get the 500 c or 1000 c it will charge ...

Adding a heat sink may not be necessary. But that won't stop some of use from doing it anyway. ;) They are dirt cheap, and IMHO improve the looks. I bought a bunch of thin versions just for the zero, 6mm for hats from Adafruit. I have a heat sink on every Pi I own except the one Zero I have in an of...

Re: I setup ultrasonic Sensor without resistors

A lot of these devices are for use with an Arduino or a Pi. The Arduino uses 5V logic and the Pi uses 3.3V logic. It depends on the device and the manufacturers hookup instructions which supply you use. Some devices say 3.3V logic safe etc. I have a DS1307 that uses 5V even when used on a PI, but my...

You can power both from one power supply, providing that power supply can provide enough current to run both. The cable you linked to, powers the Pi from the display board.
