Nice job, Nathan! Did a bit of visual polish, updated AMS symbol to be more compact. Big changes: Added new TPS63070 SPS circuit from solar board, redid LEDs on magnetorquer. BLDC LEDs should be that way too, but no reason to have 6 LEDs...

Cosmetic fixes: Added labels. All resistors and capacitors are numbered. Updated the symbol of the encoder. Updated the symbol and package of the STSPIN230. Boxed LEDs and placed a note "NP FOR FLIGHT". Other small fixes...

Design review with Nathan. Lots of little changes, mostly cosmetic. Moved from Protocard to smaller ACS board by removing protocard junk.

Removed unneeded text and did some cleanup. Everything looks good except the encoder has a CSn pin that needs to connect to the F0 MCU somehow. The CSn pin is for SPI chip select. Where do we connect this?

Added the encoder to the schematic. We need to configure the F0 to have a SPI chip select pin to connect to the CSn pin on the encoder.

Updated the symbol of the op amp and reorientated the components so it actually looks like a non-inverting amplifier. I also started assigning the GPIO pins. I am using a HEX SPDT switch to switch the GPIO connections between the STSPIN230 and the STSPIN250.

I added in the STSPIN250 IC. I chose capacitors and resistors by following directions from its datasheet and refrencing the ST motor shield as well.
