Fruku Evi User manual

/// Evi Build Guide
Thank you for choosing one of my products! Please follow this build guide
thoroughly, even if you are an experienced DIYer. The order in which
components are placed on the PCB is meant to make the assembly process as
easy as possible.
Disclaimer:
Everything you do while assembling the kit/PCB is at your own risk. Fruku is not
responsible for anything that might happen during assembly of the kit/PCB.

/// Resistors
Start with soldering the resistors, these need to be placed
“standing up”. Make sure the “bend” is as low as possible
(see picture). The values of the resistors are written on the
tape. If you are unsure, use a Multimeter to check the value.
Check the BOM file, there you will find which resistor values
correspond to the part numbers written on the PCB.
After soldering the resistors it should look like this:
/// Diodes
Now solder the diodes, look at the BOM for the values and placements. Diodes
are polarized so please take notice of the positive and negative side.
After soldering the diodes it should look like this:

/// Capacitors
Now solder the capacitors, look at the BOM for the values and placements.
Please take notice of the positive and negative side with the electrolytic
capacitors. The electrolytic capacitors need to be placed on the bottom side of
the PCB.
After soldering the capacitors it should look like this:
/// Power Header
Insert the 10 pin power header into place.
Solder one pin and check if the header is aligned flat to the PCB. If not, slightly
press down on the header and reheat the pin, it should slide into place. Now
solder all remaining pins.
After soldering the power header it should look like this:

/// Jack sockets & LED
Insert the jack sockets and the LED (beware of the orientation of the LED) on
the top side of the PCB. DON'T solder yet! Now place the front panel over the
jack sockets and use the two nuts from the jack sockets to hold the front panel
in place. Push the LED up and into the hole in the front panel, then bend the
legs so it won’t slide down.
Now solder the jack sockets and LED.
After soldering the jack sockets and LED it should look like this: (front panel
taken off)
/// IC
Please don’t use an IC socket because this will make the module too wide.
Take the IC out of the foam. Usually the IC doesn’t have its legs bend far
enough to fit in the PCB, so bend the legs to 90 degrees using a flat surface.
Then insert it while taking care that the notch (or dot) matches the notch on
the silkscreen of the PCB. When you are sure you have placed the IC in the
correct orientation you can solder it in place.
After soldering the IC it should look like this:

/// Front panel
Now place the front panel over the jack sockets and LED and use the nuts from
the jack sockets to hold the front panel permanently in place.
/// Testing
As a last check, look over the PCB and check the soldering, check for shorts and
polarity.
Insert the power cable (red stripe down) and connect it to your modular
system.
Turn on the power. Check if nothing blows! If all is well, proceed: Patch :)
/// Troubleshooting
If the module does not work, check the orientation of the IC, electrolytic
capacitors and diodes. Check your soldering. It should be perfect, like in this
