It can require that, but only when it uses USB3.0-PD.

- bsder 8y agoThat's not entirely correct. It seems like the issue is current spikes, and those can occur under far more conditions (HDMI, external USB devices, etc.). I suspect that beefing up the power system filtering would reduce the power supply maximum current requirements quite dramatically.
- dcbadacd 8y agoWhat I meant is that I'm annoyed by the lack of compatibility with standards that could provide the required amount of power to a rPi, the current microUSB implementation is awful and shouldn't be repeated.
- bsder 8y agoAh. My comment was more along the lines of "If they redid the power system with better filtering, they could make it work with 5V, 500mA and operate on standard USB." However, Broadcom won't give us plebians access to the documentation, perhaps I'm being too optimistic, and this really is the best they can do. The Beaglebone Black guys seem to work inside a 5V 500mA envelope quite well. At the very least, they don't seem to have anywhere near the issues that the RPi folks seem to.
