Marbles Assembly Instructions

Important note: This is a guide to assembling our finish-it-yourself kit. The SMD parts are already populated, and the firmware is pre-programmed.

HEADER AND VOLTAGE REGULATOR

Place the 10-pin power header on the rear of the board exactly as shown below, with the notch facing down. Carefully turn over and solder in place.

Place the voltage regulator on the back side of the PCB so that it lines up with the corner of the PCB (as in the picture below). Carefully turn over and solder in place.

LEDs

First, slip the LED spacers on all of the LEDs. The white spacers fit the 2-pin LEDs; the black spacers fit the 3-pin LEDs.
