This is a mount for Raspberry Pi 4 and Armour case for the open mower project. Fits in a YardForce classic 500 mower. You can also mount the Pololu AltIMU-10v5 but i do not recommend at because auf interference.
I recommend to cut a M4 thread in the existing pins in the mower case. No need for cutting M3 thread in the baseplate for the clips.
