BrickPi3 can now be stacked!

I’m not sure what would have caused the issue you described, but here are a few things I would recommend checking.

  • Ensure the BrickPi3 boards are stacked correctly, with proper header pin alignment and adequate depth.
  • Power each BrickPi3 with it’s own battery pack, with both power switches in the ‘ON’ position.
  • Make sure the RPi header pins are configured for the BrickPi3: enable SPI, and ensure the SPI pins are configured for SPI communication rather than as GPIOs.

If the issue re-surfaces, try the above, and report back if it’s still not working.

Somehow after they’ve been both shutdown for a few hours the issue disappeared and everything worked as expected! Thanks.

I’m here from the fuuuuuture, where brickpi3 stacking still doesn’t work.

I got two boards. When both plugged in and addresses assigned, only one is visible (always the same one, doesn’t matter its order in the stack). Doesn’t matter the stacking order or power settings. Separately both boards work fine.

The only way I found where both are visible is if I connect one first, power the pi, assign address, then HOT-STACK the second one on top of it. This causes Pi to reboot and after that both are visible. As long as the first board remains powered, it’s visible.

We reached out via email, and never got an answer from you. BrickPis can indeed be stacked.
