alt Hacker News> Basic phone charger <1A USB power supply was not enough to even finish booting, but a ~2A was enough to boot and launch octo4a
So it's drawing >1A over a single diode? Let's say 1.4A and 700mV voltage drop over the diode, then it's roughly 1W over the diode. Won't it get pretty hot?
The diagram calls it a 1N4001 which is rated to sustain 1A (but 40% over is probably fine). A safe 1N5400 would still be pennies.
