The Great Search: SMT PTC Fuses
For the KB2040 board we're working on, we want to add a PTC fuse. These fuses auto-'heal' after they cool down and they're pick and place friendly, so they're easy to use. We're going to add one to this board so it has similar behavior as the Pro Micro it is pin-compatible with. PTC fuses are available in a few different voltages, current ratings and sizes - let's find the one we need for this tight-fit PCB!
