Ghani Lawal- Corrected the LT1054 -5V regulator inverter power output label and retraced the signal
- Finished sourcing replacements for 0201 components, will use 0603 minimum from now on
- Changed 0603 footprint to hand solder version, and changed 0402 footprints to 0603 hand solder version
- Decided to keep the two
parallel 1uF capacitors instead of replacing them with one 2uF capacitor
- The 2uF cap is $3.78, just for one
- Using parallel caps in power supply circuit to achieve equivalent capacitance is fine, in fact there are advantages https://eepower.com/capacitor-guide/applications/capacitors-in-parallel/#
