Take precautions with regard to electrostatic discharge (ESD) safety. Handling components should be done in
electrostatically safe environment. Use personal and workplace grounding. Any discharge (even a minor one)
from body to a component may permanently damage it.
Our PCBs have silkscreened both component values and designators nevertheless we highly recommend you to
print out files with component placement before you start assembly of the module. And, please, at least take a
look on this manual!
Some components are marked as NU (not used) – leave those unpopulated! Some components are market as
OPTION (those are for optional modifications) – leave those unpopulated for now.
ASSEMBLY
1
Solder resistors and diodes on both PCBs (Controls board and Main board) and ferrite beads on the controls PCB!
Pay attention on orientation of diodes! In order to save space and make the module more compact, resistors on
main board are installed vertically
(you also may want to replace them with 0805 smt resistors).
See the close-up
for correct installation! Pay attention on resistor placement – don’t accidentally install them in the testpoint hole!
2
Solder IC sockets on the Main board, capacitors, jacks, potentiometer, switch and the pushbutton on the Control
board!
