Finally got my pledge for the Kickstarter Raspberry Pi Pi18650 dual battery hat that I supported.
The previous repair lasted for almost 9 month. Today the Power over Ethernet (PoE) hat from pi-supply.com that is powering my ADSB receiver died again when a thunderstorm was passing overhead. Like last time, no direct lightning but according to weather monitoring we got several >150kA flashes within 3km distance. As a result, again, the DC-DC converter Silvertel AG9805-M on PoE ceased to work. This time no short on the inputs, but no output voltage. Even having some more spares add hand I decided to replace this converter by a TDK CCG15-48-05S. This one has a higher input voltage tolerance, up to 75V and hopefully a better surge protection. Let’s see how long this last.
