PERCALL V1- ASSEMBLY GUIDE – MAY 2020

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:

www.befaco.org/howto/

   

  

You will be soldering both boards at the same time. Keeping them in the panel together might help you through the build.

Check last pages of the Build for PCB pics to help you identify components.

HAVE FUN!
