Polarity detection diode, D1, error #26

Closed micromouseonline closed 1 year ago

micromouseonline commented 4 years ago

The mainboard schematic shows D1 (polarity protection) to be a 1N5401 or similar.

That part is too large for the board.

A suitable alternative would be a 1N5197, 1N5818 or 1N5819 Schottky barrier diode.

Smaller rectifier diodes such as the 1N4001 will also work just fine.

Note that none of these parts is going to be happy with a full on short across the supply.

D1 has been resized and move in V1.3 (kicad)
