Illumination Driver PCB
The Illumination Driver PCB shown in
is controlled by the Controller PCB over a flex cable.
Power can be input to the Illumination Driver from a lab supply. The Illumination driver provides reverse
bias protection and supplies power to the Controller PCB over a separate cable. The Illumination Driver
has outputs for one to three illuminators. These are typically LEDs, but it is possible other illuminators
could be used. See
for input and output specifications of the EVM. Depending on operating
conditions, some parts and surfaces of the PCB can be hot.
CAUTION
Hot surface. Contact may cause burns. Do not touch!
