OK.
thanks roger, i was concerned about.....VK3KYY wrote: ↑Wed Jan 29, 2020 10:32 pmYes.
I think that would be OK.
I'm not really sure the diode is necessary. They normally only fit diodes in situations where people can apply the power the wrong way around e.g where people can insert a battery the wrong way around.
But in this case, it seems unlikely that the power supply would ever input voltage with the polarity reversed

The diode protects the TP5100 from sudden death in case you switch off the power and the inductor produces a uncontrolled reverse polarity. I killed quite a few boards until I realized this.

dont want to keep buying boards when they take a week to get here
