Improvements after second design review
- “Double rectifier bridge to have the right polarity in each cases”.
-> in all cases / in all supply configurations
- U5 pin 1 not connected with a blob to P3V3.
- Double transistor in a single housing rather special, I assume.
Better to have two separate ones.
- DS18B20U+ is also a unique ID IC.
- “Place 0 ohm close to the track to avoid creating a stub”. Not clear
as instruction.
- Replaced by "Make one pad of the 0 ohm resistor overlap the
external clock signal's path in order to avoid creating a
stub."
- Some components should not be mounted. Mark in schematics and in
BOM. (e.g. R33)
