Small project : Simple CV source module (Patreon)

I have made a CVsource module.
It does not have enough features to make a video, so I will publish it on patreon.

4HP , 3 outputs.
Output voltage is adjusted by POT.

The front panel and control pcb are appropriated from the past noize module. 

Output range:
A.-1~+1V
B.0~+5V
C.-10~+10V
