content: Funnily enough, I saw one of these in a recent Signal Path repair video and asked about them, he pointed me to Tindie but at the time all Tindie sellers were out of stock:https://youtu.be/ULY8CM2K194?t=261I have to say, I'd buy one instantly for convenience but white pcbs? I'd pay a premium for black soldermask and ENIG plating because that looks great (even if finding traces is harder in development), but white pcbs..... Its like nails on chalk for me. I'm hovering on the buy button so conflicted right now.

content: I see. Yes, Black+Enig would look great.I keep it in mind for the next batch and have a look about the price.Cheershammy

content: I've ordered one as the price is very reasonable for the amount of effort saved spinning something through JLCPCB myself.Did you try shrouded jacks with this? I.e.https://uk.rs-online.com/web/p/banana-connectors/7531633/I'm concerned they might put too much turning moment on the PCB, but most of my cables are shrouded.If you're thinking of a second spin, I was thinking about bringing the sense lines from the back onto the front as a pair of shrouded jacks so that I can do four wire load sensing easily, and adding a switch like this:https://uk.rs-online.com/web/p/toggle-switches/1245919/To short the remote sense lines to the front input jacks when I don't want to run four wires.If you do another spin I'd also use all the board space (and both sides) to run copper between the terminals, may as well and there may be some serious current (60A+) passing through these traces so the lower the resistance the better. Also, did you check the track spacing supports 150V/300V? I don't think adding a cutout is possible given you need structural strength to support the jacks.

content: Hi toastedcrumpetsthe jacks I use are the ones on the photo you can see on tindie. They have M4 nuts, like the most jacks with screws.The 1,6 mm pcb is robust. No flex with dangling cables.Regarding 150V or 300V: The minimal clearance between both sides is 9 millimetre. This should be ok.Sense lines and bigger tracks on top and bottom of the pcb - for higher currents - are a good idea. But with more parts it would be better to sell a kit for DIY assembly. To make sure everything fits together?Just the PCB is the cheapest option for all buyers. For the first run I want to keep it nice an easy.Thank you for your ideas and your order!Cheershammy

content: There's an adapter board on ebay right now with connectors included. They're also the ones that support standard banana jacks as well as the shrouded ones too.Board has super thick traces on both side for high currents and a 170mil trace spacing so can probably do well over 150V. So far it's been awesome to use, no more jamming banana cables on those lugs.Worth checking out: DC Electronic Load Banana Jack Adapter Boardhttps://www.ebay.com/itm/DC-Electronic-Load-Banana-Jack-Adapter-Board/154246499734?hash=item23e9cecd96:g:hb8AAOSwZ2FfSeuR
