I can now confirm that fitting a Schottky diode to the Armmite F407 instead of the 0R link (or 500mA fuse according to the circuit) works fine. I used a 1A 40V size SOD123 (1206), supposedly similar to a 1N5819. They were only about 2.40 UKP for 10 on ebay.
I feel happier with the USB input protected. |
