I'm relatively new to DIY electronics so please forgive me. My question is in regards to the "Regular for Jmp1-3 and the rest" below. As a note, I had purchased mine from Van Daal.
I was only given 8 of those pins out of the 20 shown on the right hand side of the photo. So far I have soldered 2 on for the Jmp1 and 2 for the Jmp2. From the directions it states Jmp3 is not required, but only for the DFU. So would I need to solder/unsolder the Jmp3 every time I need to update the firmware? Or just for the first time I turn it on? Or not required at all?
Secondly, in the photo below, it shows various pin headers (two 5 pin headers, one 2 pin header) connected yet in the directions it states that these are "optional". Is that true that these shown below are not required?
Since I was only given an 8 pin stick for headers, you may see my dilemma. Luckily if only the Jmp1 and Jmp2 are required, I would have just enough pins left for the In/Out (pictured below).
Once again, I appreciate the help. Please forgive me if these are newbie questions, but with this being my first synth I've built and seemingly not given enough header pins to work with, I want to make sure I do it right.
