2 years ago Here are my raw notes. I will clean the up soon....
Notes
- No datasheets linked in schematics (not sure if it is possible)
- check in chrome on windows. See if this is even a feature in kicad.
- part number in BOM digikey or manufacturer? it is manufacturer
- Vss ref on stm32 looks weird? ignore for now
- 3v3 is the output of U1 but doesn't appear to be labeled that way.
- add 3v3 pwr net
- To give the clock High and low signals do you need a current limiting resistor?
- look into this
- Are we able to reset the micro easily or should NRST go to a gpio connector add a button.
- Do we want the extra inductor and capacitors for VDDA? (Section 6.16 on the stm32l0 datasheet)
- What are the puff capacitors on the oscillator for?
- Pin 5 on J2 should be connected to ground? DONE
- Verify regulator is setup properly
- This looks good to me.
- check that the clock is setup properly
- This looks good except for the note I made.
- verify LED won't blow
TO DO
- check against stm32 ref design (Getting started with the stm32l0xx)
- Check that all the pins are connected to connectors
- you can program the chip
This issue is just to document the discussion centered around the schematic review of the design with the alternate stm32 lfqp package.
