  • Aw man, you design a whole product around a Freescale 3-axis Digital Accelerometer and a Honeywell HMC5843 Magnetometer, then a couple of months later you can buy a single chip combining both of these for less money - I can't keep up!

  • The datasheet does clearly state that it's operating voltage range is 2.16V to 3.6V?
    What makes you think a PIC is less reliable at 3.3V than at 5V?

  • The Chinese copying and reverse engineering western designs? Surely not...! :P

  • The datasheet states that the minimum operating voltage for this module is 3.0V.
    I presume this would work fine from 3.0V then?
    As you state "3.3V operation" in your "Features" section, I'm not completely sure!

  • One thing I've noticed about the PolySwitch resettable fuses is the tripping time.
    This is generally very good for fuses designed to trip at say 0.4A - they can trip in 0.02seconds! However, I was trying to implement some sort of reverse polarity protection in a motor controller circuit whereby the motors together could easily draw 3Amps from the 24V supply while running. The fuse therefore had to be rated above this to allow the 3Amps to pass and when you get into this territory you're talking about 5seconds for a Resettable fuse to trip. This would be useless for reverse polarity protection!

No public wish lists :(
