> I don’t think it’s a power issue as it’s getting 5V1A from a power outlet directly to USB-C into the device.
It's not the total voltage/wattage the PSU can provide, but the voltage at the processor.
The ESP's varying current draw notoriously causes too much noise and a lot of boards don't have large enough decoupling capacitors so the voltage drops too much and it glitches out. Also a warning that USB PSU's can very MASSIVELY in quality (I'd suggest an apple one for testing if you have one handy).
I think you're right that the RISC-V processor is either better behaved and draws power more consistently, or the board has shorter traces to it's bypass capacitor or a larger bypass capacitor.
This is correct, I thought it wasn't and was going crazy trying to debug my Pi 3 resetting my 3D printer every time, with any of ten power supplies I tried, including a configurable bench PSU.
I switched to the official Pi PSU after someone said "trust me on this" online, and yep, zero issues in all the years since.
It's voltage for Pi 3. They forgot to account for voltage drop due to protection or something. Official as well as third-party Pi 3 specific adapters are rated at 5.1V to mitigate that problem.
Early alexa devices also have power supplies that are rated at 5.2V, those could be an alternative. I also had a good experience with a 30W oneplus warp charger after some power issues with cheap 5V2A ones.
