    Whenever I ask for a design review, I need you to test each of these individual aspects one by one: - All reset/enable have an external pull-up or pull-down resistors - None of the floating pins require pull-up or pull-down resistors - All resistor’s voltage rating is sufficient for the maximum voltage applied. If any resistor doesn't contain voltage rating please flag this clearly as an error.

    Picobuck Led Driver (AL8805W5)

    (AL8805W5) The PicoBuck LED Driver is an economical and easy to use driver that will allow you to control and blend three different LEDs on three different channels. By default, each channel is driven at 330mA; that current can be reduced by either presenting an analog voltage or a PWM signal to the board. Version 12 of the board adds a solderable jumper that can be closed to increase the maximum current to 660mA. The new voltage regulator also increased the voltage rating on the various components on the board, allowing it to be used up to the full 36V rating of the AL8805 part.
