The schematic is divided into 2 parts: the pin header and the accelerometer IC. There are communication series resistors on the input/output lines. The accelerometer Has power supply decoupling capacitors as well as a decoupling series resistor as advised in the datasheet.
A custom footprint was required for the ADXL345. This was done by following the measurements given in the recommended printed wiring board section of the datasheet (p.35).
The design goals were to create a functional, testable and small development board. It is intended to be soldered with male pin headers and offers a silkscreen drawing for reference to the direction of axes.
