Revision to Connector and spare part numbers

David Crocker

The small green component bearing the letters 'bF' is the self-resetting fuse, and the component with stripes is the optional 10K resistor. A piece of Kapton tape was put on the board first to provide additional insulation.

PCB revisions 1.03 and later have a 1A mini auto blade fuse protecting the fan circuits when the fan voltage selection jumper is in the VIN position. Here is an example of a suitable replacement: You can increase the fuse rating to 2A or even 3A if your fans, air pumps etc. draw more than 1A in total.
PCB revision 1.04 has the same 1A fuse for the fan circuits and also a 15A fuse for the bed heater circuit and a 7.5A fuse for everything else. These are mini blade fuses. The 1A can be a little hard to find but the other ratings are widely available.
