have you been luck with getting the adapter boards?
it seems this thread is near to death...
No, gionad not responding. I have done them myself and ordered yesterday.have you been luck with getting the adapter boards?

So sad that this thread is pretty much dead. I guess I am late with my build.
For JP5 you may use Samtec SSW-105-01-S-T +TSW-105-07-G-T
Important: while looking back at Gionag's PCB (and yours), the debounce circuit as implemented seems weird (and to me eyes incorrect).
In case, I have redraw the way I would have implemented it myself.
i don´t see the +3.3V connected to the adapter PCB...
you have drawn pin9 (from P10 connector) as +3.3V but in schematic it is pin13 (see attached)
i am a bit confused...

Stones, you are right for the GND pin location.
Gionag, you have the others pins PC6, PC7 and PC8 correctly marked on the spare I/F.
PC6 => SPARE5 (pin6)
PC7 => SPARE1 (pin2)
PC8 => SPARE0 (pin1)
GND (pin 12)
Spare connector pin numbering (from bottom view)
5 ..... 1
10 .... 6
15 ....11
so the correct pins of P10 would be PIN1, PIN2, PIN6, PIN12 and PIN13...

Eric, thanks for those. I was prepared to use three single row pin header strips with the female counterparts.
Ok, so we have
J2 pin3 - Ch_A2 - PC7 - P10 spareIF pin2
J2 pin5 - SW2_2 - PC8 - P10 spareIF pin1
J2 pin7 - Ch_B2 - PC6 - P10 spareIF pin6
GND - P10 spareIF pin12
+3.3V - P10 spareIF pin13
Here the dual encoder adapter board.
Use for
Mechanical encoder: C2,C3=10nF, R3,R4,R5,R6=10k
Optical encoder: R5,R6=0R, C2,C3,R3,R4=void
J2 pin3 - Ch_A2 - PC7 - P10 spareIF pin2
J2 pin5 - SW2_2 - PC8 - P10 spareIF pin1
J2 pin7 - Ch_B2 - PC6 - P10 spareIF pin6
GND - P10 spareIF pin12
+3.3V - P10 spareIF pin13
Here the dual encoder adapter board.

Hi,
are you sure about this ? :
First is Muse attenuation, second is UGS module and last is buffer. ? From what I can see from your video, you have: First Muse attenuation, second buffer, then the UGS module ?
Or, maybe you have done some modification, that I don't see ?

Sounds OK to me now.
I just noticed there is no thermal relief on the GND pin of P10.
Also check if there is enough clearance between the dual encoder adapter board and the Debug I/F (P1) - probably no issue if you placed a right angle header on P10.
Got inspired by PASS XP-32 characteristics?
Me too. Here is my own implementation of a low output impedance UGS stage in an all_in_one module (shown here on my module test-bench).
In my case, I started from V4 but ended-up in a slight modified architecture to set the gain (using LTspice was quite helpful).
Besides the whammy style buffer, I also added a dc servo (output offset << 2mV)
All hand-soldered and getting old so be indulgent with my solders - one day I need to invest in a small reflow oven.
