I have an older accelerometer breakout board that I now want to experiment with, but I don't know if it needs 3.3v or 5.0v. It's the same size as the new boards, but it doesn't have any of the new numbers - just shows "E8 Analog" at the bottom and has pins for ST,Y,X, Gnd & Vdd. The chip has 21269 and some other stuff I can't read even with a magnifying glass.
Is there a user manual or other info on the site somewhere?
Thanks!
