Description

The task is to replace the current piano (cam, bat, mic, gps/gsm switch) in the power schematic with 3 of these:

Please don't add a switch to the battery line, we don't need it anymore.

Make sure to:

  • check current ratings, if these are too weak, find alternatives or maybe use switch activated FETs?
  • add the correct symbol, footprint, 3D model (step)
  • follow the contribution guide (see main page)

Research direction
Investigate the current ratings of the CSS 1211MC switch (linked) and compare to the circuit requirements in the power schematic. If insufficient, consider alternative switches or a FET based solution. Add the correct symbol, footprint, and 3D model to the component library. Follow the contribution guide in the repository. The relevant files are likely in the hardware/schematics directory.
