Module Description:
based on the Arp 4012 Idea
Resonance CV Vactrol based
easy to build
less wiring
skiff friendly
powder coated and silkscreened Aluminium panel
only 2 SMT components
10/11mm leadspace (no bloody fingers like eurorack 7mm leadspace)
leadfree pcbs
Connections:
3 Audio Inputs
3 CV Inputs
1 Resonance CV input
1 Output
BOM:
THIS BOM ISN´T approved, because we changed in last release the CV-resonance circuit, but i´m sure you left at home few standard resistors or capacitors.

Buildguide:
Short version:
start with the SMD Parts: 2 x diode on controlboard
assembly the potted PCB
assembly the controlboard, SW input pin 2 must be connected to SW output pin 2 (see picture)
mount all spacers for frontpanel and potted module, the 4x 12mm spacer are between controlboard and potted module, the other 4x 12mm spacer between potted pcb and DIYSYNTH cover pcb.
