VS1000: Evaluation Kit EVBA_2.0
EVBA_2.0 – is a “plug and play” Evalu ation Kit for Safran Colibrys VS1000 accelerometers line.
To facilitate the integrat ion in user environment and easil y verify the excellent performanc es 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

1 EVBA_2.0 description:
1.1 General overview
The EVBA_2.0 is a Kit containing 3 components:
- 1 analog evaluatio n board with soldered V S1000 of c orrespond ing G range. Evaluation board contains
electronic circuits to achieve a preliminary signal conditioning
- 1 * header connector “J1” with 14 pins (to be soldered onto the EVBA dedicated pads)
- 1 * mating connector (14 pins) including 13 cm length signal cable ribbon
The EVBA_2.0 is protected from outside atmospheric condition effects (temperature, humidity) by a vacuum
sealed electrostatic conductive plastic bag
power supply and buffers
Note: MEMS accelerom eter and electro nic cir cuits on t he EVB A can be dam aged
placement should be done in accordance with strict ESD control
Please check the integrity of the plastic bag and report if any damage or if the bag
is open on arrival.

TECHNICAL NOTE
1.3 Electrical connections
It is the user choice to mount Header connector (Figure 1) on J1 connecting pads or to solder the signal wires
directly on the EVBA board. The size of the soldering hole are of 0.8mm, so wires up to a conductor area of
0.5mm2 or AWG21 are suitable. The wires or the Mating connector (Figure 2) will ideally be hand soldered
using a PB free solder with the appropriate flux.
Note: Connector J1 is a 14 Positions Header, Shrouded Connector 0.100" (2.54mm) Through Hole, Right Angle
This connector is delivered unsoldered to the evaluation board. The user is free to use it or to solder any
connection directly on the board.

1.4 Mechanical dimensions
The mechanical layout of the evaluation board is shown in Figure 3. All components are soldered on the top
and bottom surface and the board can be mounted using the 4 x Ø3.40 mm through holes:
Note: This is for the VS1002, other range looks like same
