I'm not sure if anything's changed from the original module to the kit, but at least with the original the board was exactly the same for both the 3.5mm and banana version.
Cinch/Johnson bananas won't fit without modification as Matthias mentions... the original used banana jacks which looked very similar to these (I don't have it anymore so I can't verify if the dimensions provided are the same, but I'd imagine so): https://www.ebay.com/itm/50pcs-Banana-Jack-Socket-Binding-Post-Test-Probe-for-4mm-Banana-Plug-Black-Red/264765586993?hash=item3da5423e31:g:Y0oAAOSwiX9e6I-9.
