Shortening the carriage
lighting
You can divide or shorten the print
at the marked spots!
Caution:
Pay attention not to damage the
connection pads or the parts on
the PCB when sawing.
After shortening the PCB you get :
Section 1
with
integrated function
decoder,
with
integrated
smoothing capacitor,
with
connecting points for
external bridging capacitors and
light dependent resistor (LDR)
Section 2
without
integrated function
decoder,
without
integrated smoothing
capacitor,
without
connecting points for
external bridging capacitors and
light dependent resistor (LDR)
