Just like its big brother, this LED Distribution Board has a 20ma current source on the board top surface to provide highly regulated current for up to 4 LEDs. This source will support 20ma LEDs of any color and colors can be mixed within the group. Solder pads are provided for optional brightness-adjustment resistors to allow individual control of intensity of every LED if desired. The bottom side of the board provides connection for up to 4 additional LEDs, which can be connected as one or more series groups, individually (parallel) wired LEDs, or a combination of both. These connections have solder pads for LED current control resistor placement. This module will support a power supply input voltage of up to 18 volts-DC. A nylon spacer for mounting is included with each board.
