ASSEMBLY
Putting together the IC2BS is a simple task if you’re familiar with soldering
electronic kits. You’ll need a #2.5 hex wrench, soldering iron, tin solder, flux and
wire clipper.
These instructions will guide you through the whole process.
Electrostatic discharges, or ESD, can occur when two electrically charged objects,
such as the human body and an electronic device, come in contact with each other. This
phenomenon can be of the order of several thousand volts and can destroy integrated
circuits, like the LM386, PT2399 and ATMEGA328P. To prevent this from happening, touch
a metal surface, like a door knob, before handling any IC.

USER INTERFACE
MAIN PCB
Start by snaping in the nine potentiometers in place. Follow the BOM to ensure the
correct values.
Follow this by placing the power switch and solder all the components.
The eight pin male headers will be assembled later.
Start by soldering the Li-Ion Charger and DC Booster modules first. To do this, apply
flux to the pads on the Main PCB and place the modules in their correct orientation on
the Main PCB. Secure them if needed and apply heat with your soldering iron on the pads
of the modules. Apply solder to the pads of the modules and let the solder flow into
the pads on the Main PCB, securing them together.
Do the same procedure to solder the 3.5mm jacks as well as the 18650-cell socket on
the underside of the Main PCB. Ensure the correct polarity on the socket.
Follow this by placing the remaining components on the Main PCB. Start with the
smaller ones such as resistors and ceramic capacitors.

8
Notice that the electrolytic capacitors and the LED have polarities and must be
installed in the correct orientation according to the silkscreen on the Main PCB.
Solder these components and trim the leads.
Insert the IC sockets in their correct orientation.
Solder the sockets and only then install the provided ICs.
Insert the eight pin female header on the Main PCB and the eight pin male headers on
the User Interface. Secure the two PCBs with the provided brass standoff and screws and
solder the headers.
Finish off by cleaning the flux left behind and perform a visual inspection.
The side wood panels can be installed by sliding them into the two tabs on the Main
PCB, with the mounting holes facing upward. Insert the aluminium standoff and then the
brass hex screws. Secure them tightly.

BOOTING UP
Insert a Li-Ion 18650 cell in the battery holder with the correct polarity.
Connect a micro-USB cable and a red led should light up on the Li-ion charger
indicating the battery is charging.
Flip the power switch and the LED in the middle of the Main PCB should light up, as
well as a red LED on the DC Booster.
