EVAL-ADXL362-ARDZ Shield

The EVAL-ADXL362-ARDZ shield illustrates the functionality of the ADXL362 - an ultralow power, 3-axis MEMS accelerometer.

The ADXL362 is capable of measuring dynamic acceleration (resulting from motion or shock) as well as static acceleration (gravity). It provides 12-bit output resolution and has three operating ranges, ±2 g, ±4 g, and ±8 g. Additional useful features include an on-chip, 12-bit temperature sensor accurate to ±0.5°, motion triggered wake-up functionality, and and several activity detection modes which makes is ideal for portable low-power instruments.

The EVAL-ADXL362-ARDZ Shield is designed in Arduino Uno R3 format which makes it suitable to used with both Arduino Due (e.g. EVAL-ADICUP360 based board) and Arduino Uno R3 base boards.

The EVAL-ADXL362-ARDZ board has a large capacitor(C18) on the board which holds charge for the LCD screen. When power cycling the system, you must wait approximately 5 seconds to allow enough time for the capacitors on the EVAL-ADXL362-ARDZ board to fully discharge. This is a power requirement for the ADXL362, which notes in the datasheet that the power rail must come all the way back down to 0V before powering back up.
