Witch v1 Rev. May22 - ASSEMBLY GUIDE
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. Keeping them in the panel together, until stated to split
them, might help you through the build. Check the last pages of the Build for PCB pics to help you identify
components.
