A big change occured in the new board: Instead of three coils there will be one permanent magnet to align the satellite to the earth´s magnetic field.
This will have the advantage of detumbling and stabililzing the satellite.
The remaining axis can be controlled by a reaction wheel (mounted on the right side).
It´s basically a small motor which changes the rotation around the mounted axis. This axis is perpendicular to the two others magnetically stabilized axes, so you can change the camera´s perpective instantly while maintaining attitude stability.
Board is going in production asap.
