The sensor is soldered onto a PCB with four mounting holes (in case you don’t remember, this is accelerating at up to 200g’s!) and a 3.3V regulator so you can use it with 5v logic such as an Arduino. We also add 0.01uF filter caps for 500Hz output bandwidth.
This breakout comes with 3 analog outputs for X, Y and Z axis measurements on a 0.75″x0.75″ breakout board. The analog outputs are ratiometric: that means that 0g measurement output is always at half of the 3.3V output (1.65V), -200g is at 0v and 200g is at 3.3V with full scaling in between.
Fully assembled and tested. Comes with 8 pin 0.1″ standard header in case you want to use it with a breadboard or protoboard. Four 2.5mm (0.1″) mounting holes for easy attachment.
The XYZ filter capacitors are 0.01uF for a 500 Hz bandwidth
