  Since you cross-posted, please see my comment in Single Axis Accelerometer Breakout Board - ADXL193 +/-250g for a reply. tl;dr: the 2g is likely to be more sensitive, but you’d have to check its specs closely to be certain.

  Sensitivity is usually a function of range / resolution (plus all sorts of data on error, etc.). I’m not sure which 2g device you’re asking about, but since you also posted in Triple Axis Accelerometer Breakout - ADXL345, just as a very basic comparison between the two:

  The ADXL193 single axis accelerometer has a range of +-250g. Wikipedia on g-force suggests that this means you could measure ‘Brief human exposure survived in crash’. It is an analog output device, so it doesn’t necessarily have an inherent ‘resolution’. However, for most purposes you’ll have to convert this to a digital value through an ADC somehow. If you’re using an Arduino, then the ADC is 10 bits, meaning you get about 1024 levels over this range. Unless you do some analog tricks to modify the linear relationship between g force and output voltage, this means you get a resolution of roughly 0.5g/level.

  The ADXL345 triple axis accelerometer has a range of +-16g. Wikipiedia on g-force suggest that this means you could measure ‘Typical max. turn in an aerobatic plane or fighter jet’. It has a digital output with a 13bit resolution. Here you don’t have to use an ADC, but will of course have to read the data correctly. The resolution here would be roughly 0.004g/level.

  So if you’re asking which one is more sensitive, the ADXL345 clearly wins. It’s also triple axis, and a few bucks cheaper. The ADXL345 is an option if you need to measure accelerations outside of the ADXL345’s range (such as its use suggested in the datasheet: for car impact airbag purposes).

  Ah, good point - fell for the A# trap.

  Should be the A10 - probably copy/paste error from the pcduino ‘1’ :)

  The hookup guide suggests that they’re 3-pin JST SM connectors, used for wire-to-wire connections. No idea if you can plug them into the EH or XH board connectors reliably. Push comes to shove, I’d just crimp a new connector onto the cable, or replace the cable altogether.

  No - if you applied 5V directly, it would quickly self-destruct. You’ll want to stay around 2.2V or, preferably, current-limit it to ~18mA, e.g. using a resistor. See: LED calculator: current limiting resistor value ( or do it by hand :) )

  The strips should work the same. From another user’s comment:

  the WS2812B. It looks like the WS2812 but it has 4 pins instead of 6. The low-pass filter seems to be built-in now so it does not have seperate power pins for the LEDs and the logic

No public wish lists :(
