SQX -
Thanks for trying that. I was afraid it might cause a problem with the rest of the board. I guess the question is if pins 4,6, and 20 are all at 5V and then the analog portion of the chip is running it 5V and the digital part is running at 3.3V, does that then drive the XBee and memory card at 5V as well??? If it doesn’t, then would that be a viable option to modify the board so that it has 5V on the analog part and 3.3V on the digital parts???
Thanks again!
