People mostly just get JLC to provide the SMD parts and solder them, then you add the molex connectors yourself.I'm considering organizing a group soldering party to build a few of these. Could somebody please help catch me up on differences between the different versions? Is this correct:
Original Version by George Rudolf - https://github.com/GeorgeRudolf/OldMacATX
@Melkhior Version - https://github.com/rdolbeau/IIci_ATX
- two-layer PCB
- 0805 SMD components
- uses Mac's soft-power on circuit
- "alternate" PCB version supports real Molex 10x2 connector or low-cost Chinese 10x2 connector
I'm not sure whether any kind of SMD soldering is reasonable to expect from people who may not have much prior soldering experience.
- four-layer PCB
- 0603 SMD components
- has a switch to select between Mac's soft-power circuit or always-on behavior
- has a power-good LED
- 10x2 connector support???
I soldered the SMD stuff myself, but I'm cheap. The NOT is a little small for beginners. Order half assembled, half not? Then people can either do just the molex, or the SMD and molex?
I recommend using the design that accepts third party connectors as the real ones are expensive.
Thing to watch is JLC weirdly use a different rotation standard to some common Layout software, so you have to check the orientation of parts. It isn't bad, you can verify and rotate / move on the JLCPCB order website as you go.
