MTN Electronics designed direct-thermal-path 20mm Triple Copper MCPCB for Cree XP series and Nichia 219/319 series emitters (3535 Nominal Size).  This dual-channel design also allows you to run 3x Cree XQ-E emitters for a secondary color channel.  

This MCPCB is designed for parallel use only, so there are no jumpers or bridging required for most triple applications.   To run all three secondary XQ-E LEDs, you must bridge the jumper pads.

The three large LED pads have an asterisk symbol "*".  This denotes the negative - side of the LED.  For the three smaller XQ pads, the asterisk "*" symbol also denotes the negative side of the LED (use "2-" for the negative connection on these LEDs; common positive).
