  • I want to use this with an Arduino, which means I want to build a level-shifter for the i2c lines, as seen in this page:
    The board doesn’t export its 3v3 regulated output. If I feed it 3.3V pre-regulated, is the regulator dropout low enough that 1) the board will work; 2) the level-shifter will work (if I put the pre-regulator “vcc” into the base of the MOSFETs)?
    Or do I need to solder on a wire and bring the 3v3 back off the board?

No public wish lists :(
