MIDI THING V1 - ASSEMBLY GUIDE – Rev. Feb 17
THANKS FOR CHOOSING ONE OF OUR KITS!
This assembly guide has been designed 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 take the time to read the steps thoroughly
before starting.
If this is your first project, please read this article before you start assembling the kit:
GOOD LUCK!

DIODES

observing their polarity
. The black or white line on the diode must match with the white line on
the diode symbol on the PCB silkscreen.

FERRITES
Solder the two ferrite beads by using a recycled resistor leg passed through each ferrite and proceed as if it were a
resistor. Ferrite beads don't have polarity.
The space for the ferrites is a bit tight. You can either leave some slack in the leads or leave them until after you have
fitted the power connector.
