Voltage Groove base Hat

Sun Mar 22, 2020 9:10 pm

Can you clarify me with one question? With a groove base hat update the gpio pins have the same voltage?

A simple Google search and reading the resulting found pages from seeed would have got you the answer quicker that waiting for some else to do you research for you.

Read the warning ..under specifications.

The sensors have 5v, that plate works with 3v3. The power for the sensors must come from the gpio pins. I have to make a different wiring scene. What wires should be bought?

You need to ask the manufacturers/suppliers, but my guess is it can't (reasonably) be done. It's not just the supply voltage, but the signalling voltage that could be incompatible and will potentially kill your Pi of the HAT.

All the groove sensors are specifically designed to work with the groove hat, so they all work at 3.3V on the pi.

I believe there are 5V versions but they can only be used on the arduino groove hat which does support 5V working.

If you want to use a sensor that requires 5V on the pi, then you can't use the groove hat, you will have to build your own interface circuit and connect it directly to the pi gpio pins.

I was reading about it... There's this one https://www.seeedstudio.com/GrovePi-p-2241.html! I will give it a try! :geek:

Again it will only work with groove compatible sensors/devices.

there is a list of them here https://www.dexterindustries.com/GroveP ... d=noscript

you still can't just connect a random 5V device and expect it to work and not damage your pi.
