hola
I was actually wondering the same thing because I’m planning to power my CoreS3 through the 5V pin for a compact project. It’s great to know that 5V input on the BAT or 5V pin is possible, but now I’ll be more careful about current limits and the regulator specs. If anyone has real-world usage experience with powering it directly from a battery or 5V rail long-term, I’d love to hear more about reliability or heat issues.
