The ADXL345 is a small, thin, ultra-low power 3-axis accelerometer with high resolution (13 bits) and a measurement range of ±16g. The digital output data is 16-bit two's complement format, which can be accessed through SPI (3-wire or 4-wire) or IIC digital interface;
ADXL345 (three-axis gravitational acceleration);
Communication method: IIC/SPI communication protocol;
Measuring range: ±2g~±16g;
Reserve IIC/SPI interface for easy access to other main control boards;
