5V to 3.3V communication

[Dave]

I also used it for interfacing to some LINX RFM-433 receivers and LINX TFM-433 transmitters in my Hopps moisture monitoring system.

I've used THIS on a couple of projects and love 'em.

Yes, works fine for me too. Do you want a second source?

Thanks guys for all the tips. Yesterday I ordered an Adafruit breakout board with the MAX31855 on board with level shifting. I will see how well this works and follow their techniques. Looks like I could have saved a few bucks if I had checked this thread yesterday. Michel, if I power the f1936 at 3.3 I will have to buy a 3.3 LCD. Andy, the Sparkfun looks like the good solution to have in your toolbox for quick setups and they supply the schematic with part numbers, I’ll pick up a couple at that price!
Thanks,
Wayne

Thanks - good price.

Any reason to not just run the PIC at 3.3V?

In my case, some of the ic's I was using can ONLY run at 5V. The only thing that could only run at 3.3V was the XBee radio. So it was simpler to run everything at 5V and convert to talk to the XBee.
