ACCEL SPI BOARD
Accel SPI Board is used to measure acceleration and gravity. The measurement on the additional board is performed by using the
ADXL345 accelerometer circuit. The additional board is connected to the microcontroller on the development board via pads and
communicates with the microcontroller by using serial SPI interface.

board to the microcontroller on the
development system or to some device
Accel SPI Board pin’s funtion:
ACL-CS# - Chip select
INT1
- Interrupt 1 output
INT2
- Interrupt 2 output
SCK
- Serial clock
MISO
- Master input slave output
MOSI
- Master output slave input
VCC-3.3 - +3.3V Voltage
GND
- Ground
Accel SPI Board is a low-power additional board, thus making it suitable for integrating into mobile devices. The additional board is
used to measure dynamic and static acceleration in 13-bit resolution ranging +/- 16g.
