The Center Solder On (CSO) is a small addon PCB that can be added to one of the slots of the Beta Main Board.


1 CSO1

The very first CSO simply had a few LEDs on it that could be made to blink in different patterns.


2 IMU CSO

The second design is intended as inertial measurement unit (IMU) and features 10 DOF (degrees of freedom) sensors: acceleration (3D), orientation (3D), magnetic field (3D) and pressure (1) it also measure temperature, primarily for internal compensation.

Chips:

  • LSM6DS3H: Accelerometer ODR up to 6.66 kHz, Gyroscope ODR up to 3.33 kHz, 2 - 5 €/pc.
  • LIS3MDL: 3D Magnetometer ODR 20 Hz, 1 - 2 €/pc.
  • DPS310: Air pressure and temperature sensor, ±0.05 m relative accuracy, 24 bit results, 1 - 3 €/pc.
