Utilizing the one of the industry’s most advanced microcontrollers and highly regulated voltage control circuitry, this total module consumes less than 40ma of current during normal operation with all LEDs attached. Input DC voltage range is 5.6 to 20 volts.
Preparing the N8110-06:
The module’s tiny size and thin construction will allow it to be placed so it is easily hidden from view. The module has circuitry both sides so care must be taken when mounting to prevent contact with metal (electrically conductive) material which could cause a short circuit. The bottom of the circuit board can be used for mounting with the small square double-sided sticky foam pad that is included.
Important note: A low-wattage iron (15-watt or less) should be used for this process and a needle type pointed tip should be used for connection of the wires to the module. Too much heat or solder can damage the wires, LEDs & module and void warranty.
Figure 1 below shows a detailed view of the wires to be connected as viewed from the front side of the circuit board.
Soldering wires to the module:
The red and black power wires should be stripped and tinned prior to attachment to the circuit module. Strip approximately 1/4” of insulation from each end of each wire and ensure the wire strands are twisted together and carefully tin each end.
Each wire’s tinned end should be inserted into the appropriate solder point with the wire inserted from the front side of the board and soldered on the back side of the board. For this process, good lighting, magnification, and a method to hold the circuit while soldering will be very helpful in the positioning of the wires.
Extra care must be taken when soldering wires in position. Because of their close proximity, excess solder can easily cause bridging between pads.
For best success in soldering the wires, place each wire into the appropriate solder hole and seat the insulation up against the hole on the front side of the board. Ensure the wire is held in that position when applying any flux and solder to the hole on the back side of the board. It is easiest if a small amount of solder is placed on the soldering iron tip first, then the wire is placed in position and flux is applied at the back side of the hole. While holding the wire in position, touch the tinned wire strand and the hole with the soldering iron tip allowing the solder to flow into the hole capturing the wire. This soldering process should only take about 1/3 of a second to provide a clean shiny solder joint with no excessive solder. Then, carefully snip the protruding wire from the solder joint. This will ensure a good joint and eliminate possible shorting. Repeat this process for all remaining wires.
Soldering the LED wires to the module requires the same care as outlined above. If the LED wires are single-strand magnet wires, ensure they are properly stripped and pre-tinned prior to soldering them in place.
Testing and mounting the assembly:
The N8110-06 Simulator assembly is now completed and should be tested prior to installation. Figure 2 below shows a schematic view of LED connections.
NOTE: This module DOES NOT HAVE reverse polarity power protection, so be extra careful when connecting the +DC RED wire and the –DC BLACK wire to your power source. Connecting the backwards will damage the module.
Once power has been applied and all LEDs appear to be function normally, the assembly can be mounted into your project. Included in this package is a small double-sided sticky foam pad for this purpose.
This completes connection of the N8110-06 module. We hope you enjoy the added realism our module provides.
