VS1000: Evaluation Kit EVBA_2.0
EVBA_2.0 - is a "plug and play" Evaluation Kit for Safran Colibrys VS1000 accelerometers line.
To facilitate the integration in user environment and easily verify the excellent performances of VS1000 sensors,
EVBA_2.0 integrates a VS1000 sensor with the user specified range, an ultra-low-noise, high-accuracy 3.3V voltage
reference, the decoupling capacitors and output buffers.
Features:
-
Low noise power supply management converting +5V to 3.3V
-
Output signal conditioning:
 buffers to enable the use of long lines between the sensor and the user electronic
 low-pass filters with a cutting frequency
-
Easy integration into system: 4 fixing holes
-
Industrial interface
