Raspberry Pi 4 - Hackdot

I like the usb-c input.

The big shortcoming of the other Raspberry Pis I have is power. Plug anything into it and you risk undervoltage problems (even with the official supply)

  [   49.910905] Under-voltage detected! (0x00050000)
  [   76.949928] Voltage normalised (0x00000000)
  [  436.806032] rpi_firmware_get_throttled: 1 callbacks suppressed
  [  436.806038] Voltage normalised (0x00000000)
  [  438.886093] rpi_firmware_get_throttled: 2 callbacks suppressed
  [  438.886100] Under-voltage detected! (0x00050000)
  [  445.126338] Voltage normalised (0x00000000)

I hope the new power input will stablize things.

I'm wondering if you could power two USB 3.0 2.5" HDD through the Raspberry Pi 4 without requiring external power supplies for them now.

Would be nice to build a NAS with as few cables as possible.

An alternative would have been a powered USB hub.

I have one system where I relented and did that, but really, for many generations of pi... why is this even a thing?

For example, recently I plugged in a USB stick and a webcam and couldn't boot. So I would boot, then then plug in the webcam ... carefully. And there were still 2 usb ports free.
