Data logging shield 5v or 3v

by AnthonyBall on Sat Nov 21, 2020 1:37 pm

I've bought a data logger shield, from the docs I was expecting to have to cut a jumper and solder to change it from 5v to 3v for the IO.

But this latest version of the board appears to be not connected to either 5v or 3v. There is no documentation as to what to do with this board - do I solder to 3v?

If you look closely, there should be a small trace between the VIO and the 5v pad. For use with a 3.3v processor, cut that trace and bridge between the VIO and 3.3v pads with a drop of solder.

There isn't. I've tested with a meter. The picture of the board you posted was the previous revision. The latest board doesn't have a connection to EITHER 5v or 3v...

("Our latest version adds power rails for 5V, 3.3V and Ground" <-- this is the latest version)

The picture I posted was from your site (mine is the same) - zoom in where I put the red arrow on my original post or look at the pictures from your site on the links below.

Then there is nothing to cut. Just bridge the jumper to 3.3v.

Bill: I think this should be documented on the website.
