DMX-512 LED Controller with LED Display

Step 8 Utilization - Output Board

All designs, schematics and PCBs, of the various types of output boards are available, check Step 1 for a ZIP or on the website.
There are various ready made current regulators that could be used, Such as BuckPlus 7021/7023 series or the VLD-350/700 constant current regulators.

Output boards will vary depending on batch, but will function the same.

Shown here, is the Common Anode Low-Profile Output/Breakout Board. It uses 3x logic level MOSFETs to control the colors. This board does not limit current, any limiting will have to be done else where, either by wiring a resistor inline with the LED or using pre-assembled modules or strips that have their own resistors. The board is small, 1.5" x 1.5" x 0.5" tall. Inexpensive and should be able to handle up to 30w per channel or so of LEDs. The bottom traces should be tinned if using more than 20 watts total.

Common Anode Low-Profile: The kit comes with the parts shown and wire. Crimps/Housing is optional.

• R4, R5, R6 - Resistors - 10 kohm 1/4w, they go under the MOSFET leads.
• R1, R2, R3 - Resistors - 220 ohm 1/6w 
• Q1, Q2, Q3 - MOSFETs - Logic Level, low resistance such as:
• Bend the MOSFET's over, line the holes up.
• Terminal block, make sure the openings face outwards
• Connect the Red and Black wires either from the bottom(shown) or through the header holes.
• Connect 4 wires from the TTL Inputs header to the Outputs on the controller.
• Attach crimps and housing if you are using them, otherwise solder directly onto the controller, remove PIC first!
• Check over the traces and solder points real well.
