Now we will mount the OLED Screen
SPACERS
Secure the 6 mm. spacers onto the PCB in the upper side of the board, to fit the OLED
screen. Place them at opposite side from components.
OLED SCREEN
This step is important, the screen has
fragile glass
and can be easily damaged. Please take
care to
be gentle
.
1.
Cut the 14p socket in half. Then place one of the halves in the 7 holes for the OLED
but
do not solder it yet.
(The other half can be discarded).
2.
Cut OLED pins to about 3mm (enough to fit comfortably in the socket).
3.
Remove the plastic row which is fitted to the OLED pins, so that once connected with
the socket, the OLED will be flat and parallel to the PCB. This step can be quite tricky
as the plastic row is fitted tightly to the pins and the screen is very fragile, so take
care. We recommend using a fine pair of tweezers for this.
4.
Fit the OLED into the socket, then screw the remaining four nuts into the spacers
but
be careful
with the bottom two screws, as they can sometimes press against the
screen. You may prefer to only place the top two screws.
5.
Proceed to
solder the socket.
TROUBLESHOOTING
Connect both boards together and power the module ON. The OLED should show Befaco
splash screen and then, main screen.
ICs
Place ICs in their sockets. Take care of polarity, notch or dot mark orientation.

Now we will proceed to mount the jacks, USB and encoder. This part of the assembly is
CRITICAL
. Please take your time and read the following instructions carefully.
These components must
NOT
be soldered until they are placed on the PCB and fully attached
to the front panel.
