I recently built a Picade using Pi4 and Picade X hat, and bartop case from AWUK. Initially it only had player 1 controls.
Player 1 has six buttons with Plasma lighting, which connect to the hack header on the Picade X. This works just fine.
Since then I have added a second player controls, also with Plasma lighting. I am trying to figure out how best to connect the 2nd player’s Plasma lights. The kit provides a 30cm plasma → dupont cable, but the Picade X HAT only has dupont pins (in the hack header) for a single plasma. In addition the Picade X HAT has a plasma connector right besider the hack header (I think it’s JST?).
Can I connect my second plasma chain to the hat’s JST plasma out, keeping the first plasma set connected to the hack header? If so I need to get a long JST->JST cable (like the 30cm one that comes with the 10-button kit).
Or is it better to daisychain the player 2 lights from the player 1 lights, making a 12 light chain, and continue only connecting via the hack header to Picade X HAT? That would also require a long JST cable.
I’ve not been able to find a long JST cable on the website. I did find this JST-SH cable - Qwiic / STEMMA QT compatible – Pimoroni but 20cm is a bit short, and I’m not sure the pin pitch is correct. Over at the Pi Hut I found JST-PH Jumper Assembly (4 Wire)– The Pi Hut and I guess I could make a cable from two of them soldered together, but again I’m not sure what pin pitch is needed for plasma.
