USB Accelerometer Model X16-1C

3.3

Mechanical

The X16-1C electronics are enclosed in a three-part plastic enclosure. The semi-transparent blue
colored ABS plastic allows attenuated sight of the two indicator LEDs. The top and bottom enclosure
components and the printed circuit board are secured together with a 0.75” long #6-32 screw and nut.
Longer screw lengths can facilitate attachment of the X16-1C to other structures. A slip-on cap
protects the USB connector. The X16-1C weighs 2oz (55g) with an alkaline battery.
