KX134-1211-EVK-001

KX134-1211-EVK-001 is an evaluation board for KX134-1211 accelerometer. KX134-1211 is a tri-axis ±8g, ±16g, ±32g, or ±64g silicon micro machined accelerometer featuring a user-configurable 3-stage Advanced Data Path (ADP) consisting of a low-pass filter, low-pass/high-pass filter, and RMS calculation engine. The KX134-1211 accelerometer also features an advanced Wake-Up and Back-to-Sleep detection with a high-resolution threshold capability configurable down to 15.6mg, 512-byte buffer that continues to record data even when being read, as well as embedded engines for orientation, Directional-Tap/DoubleTap, and free fall detection. The sense element is fabricated using Kionix’s proprietary plasma micromachining process technology. Acceleration sensing is based on principle of differential capacitance arising from acceleration induced motion of the sense element, which further utilizes common mode cancellation to decrease errors from process variation, temperature, environmental stress.
