1.1.2 Illumination Driver PCB
The Illumination Driver PCB shown in Figure 1-2 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 Section 1.2.1 for input and output specifications of the EVM. Depending on operating conditions, some parts and surfaces of the PCB can be hot.
Hot surface. Contact may cause burns. Do not touch!
Figure 1-2 EVM Illumination Driver PCBWhen choosing your LED component (not included with this EVM) the end user must consult the LED data sheet supplied by the LED manufacturer to identify the EN62471 Risk Group Rating and review any potential eye hazards associated with the LED chosen. Always consider and implement the use of effective light filtering and darkening protective eyewear and be fully aware of surrounding laboratory-type set-ups when viewing intense light sources that may be required to minimize or eliminate such risks in order to avoid accidents related to temporary blindness.
The Illumination Driver PCB contains the ports listed in Table 1-4.
