Befaco EVEN VCO Manual

EVEN_VCO V0.3.3 - ASSEMBLY GUIDE – Rev. Oct 2022
THANKS FOR CHOOSING ONE OF OUR KITS!
This manual has been written taking into account the common issues that we often find people experience in our
workshops. The order in which the components are placed on the board is meant to make assembly as easy as possible.
Some steps are not obvious, so even if you're an experienced DIYer please read the steps thoroughly before starting.
If this is your first project, please read this article before you start assembling the kit:

You will be soldering both boards at the same time. Please refer to page 7 for a component placing reference. Some
names could be small and difficult to spot.
RESISTORS
Color code can be difficult to identify, we strongly recommend to use a multimeter.
