| May 26, 2020 at 21:47 | comment | added | Roland | @Milliways Thanks for the link. However, these are REDUCED schematics. Still no voltage measurement ic to see, too bad. But it does show the Switched Mode Power Supply for 3.3V and other voltages, which dissipates much less than the linear voltage regulator on the older Pi. A power input voltage of 5.25 V or even slightly higher will be even less af a risk of burning the onboard power supply ic, while reducing the chance of lightning bolts because of voltage dips below 4.65 V | |

| May 24, 2020 at 17:25 | comment | added | Roland | @Milliways Thanks, but do you happen to know the URL of newer schematics ? | |
