New Gravity Plug

Another plug coming up – based on the BMA020? 3-axis accelerometer:

Again an awfully tiny chip, with even smaller pads. This chip has a programmable ±2g/4g/8g range with 10 bit resolution. As with yesterday’s plug, this chip communicates over I2C and supports up to 3.6V.

The schematic is obviously very simple again:

The Gravity Plug will also work with an Arduino, through the Plug Shield.

It’ll take at least a few weeks before I can test these new plugs and make them available.
