CM1 support (how to change power mode)

CM1 and CM3 VBAT power


Compute Module 1 needs 5V VBAT power for kernel, and CM3/CM3+ needs 3.3V VBAT.

By default StereoPi tuned to provide 5V voltage for CM3 series support.

To change powering for CM1 you need:

  • Unsolder R15 (0 Ohm) resistor here:
R15 resistor StereoPi
  • Solder R17 (0 Ohm) resistor or piece of wire here:
R17 resistor StereoPi

Schematic of the StereoPi board

Original StereoPi schematic was created in Altium, and now we're trying to choose appropriate open source tool. At this moment we like KiCad. If you have some ideas what tool should we use for schematic, please let us know in out twitter here:
