How does one use the PT100 Amp Board with a 3.3v controller, eg RADDs

The documentation indicates that the PT100 needs a 5v supply and provides a 5v output.

Is this usable with a 32-bit contoller? Can it be supplied with 3.3v and hooked up to a 3.3 v input?


Thanks!

Answer this question I have this problem too

Is this a good question?

Hi Duncan,

The PT100 amplifier board requires a stable 5v connection to work correctly therefore it is not possible for use with a 3.3v power input.

A stable 5v supply is available in my system, I have one to drive the bltouch. Is there a recommended solution to scale the output back to 3.3volts? Or some other solution? It looks like the amp itself will run at 3.3v.

If not, it looks like a gap in your product line given the popularity of 32 bit controllers now.

Thanks!
