1 General description 1.1 Introduction The evaluation board of the acceleration sensor provides an opportunity to verify the sensor performance and develop a prototype using an external processor e.g. Amber Pi design kit (Part No: 2609017281001). It can be directly plugged to Amber Pi design kit using the mounted I2 C interface pins. It can also be placed on a bread board using through hole pin header connections.
2 Functional description The acceleration sensor evaluation board supports the standard I2 C communication interface. • A positive supply voltage is applied to the sensor through VDD pin and I/O supply voltage for digital interface through VDD_IO pin. The VDD and VDD_IO pins on the board are connected together using 0Ω resistor R1. • The I2 C communication is enabled by connecting CS pin to VDD_IO. The CS pin is connected to VDD_IO using 100kΩ resistor R3.
Please refer to the data sheet of the acceleration sensor (Part No: 2533020201601) for more information about the electrical properties. 2.1 Evaluation board in operation 2.1.1 Pin header connection I²C Interface to external boards e.g. Amber Pi design kit R2 R1 R3 ADR Figure 2: Pin header connection to the external boards. e.g.
Resistor Description R1 VDD and VDD_IO pins are connected together R2 Open. It should be connected if the interrupt function on INT_0 pin is necessary R3 I2 C enabled. CS is connected to VDD_IO ADR I2 C address of the sensor is 0011001b. SAO is connected to the VDD_IO Table 3: Functionality of resistors on the evaluation board 2.1.
