Alexandre, you are right - that is my design error. The drivers used have internal pull-up resistors on EN inputs only, not on IN ones. To prevent LEDs from turning on while not programmed, you may solder a 4.7K..100K resistor between pins 1 and 2 of U11 on the 10369 board. the pins are close to each other, so you'll need a small physical size resistor - 0402 or better 0201 so it will fit there. And make sure the pins are not shorted together. The U11 is located on the bottom side of the 10369 board, facing 10353. Andrey
