Issues
In the previous V0.2 version, we resolved the defects that existed in the previous two versions, but after the designers’ consideration, there are still some areas that need improvement, so we redesigned the V0.3 version
- Simply relying on magnetic suction to fix each module may damage the electronic components on the host PCB
- Unstable connection of single screw hole shape
- The magnetic suction structure is not stable enough
- Post expansion connection issues
Improvement
- Add photoelectric induction switches to protect electronic components on the host PCB
- Change the shape of the screw hole to a triangle to better coordinate with the added photoelectric switch hole
- Add buckles to the host and expansion box to prevent detachment
- Add expansion connectors on the side
PCB
- power chip shortage, we have to change it.
- Can not manage the battery throught I2C.
