If the board's size or form is causing or the reason for any of the issues mentioned below, and said issue cannot be resolved without disrupting the size or form; just mention that. I understand that the size/form of this board is an important selling point.

(1) U1 needs a value. I think "AL8805" would do.

(2) The left side of the current-set jumper is really close to the resistor pad below. If we could move this up even a little I think we would be saving ourselves some trouble on the manufacturing side.

(3) Looks like the bottom-side GND trace has some funny angles (other than 45 degrees)

(4) "OUT-" trace is entering the inductor pad at an angle

(5) Got an airwire on "CTRL_CH1"

(6) Need measures

(7) R1, R2, C1, C2 and L1 all need silk (TPlace) for footprints

(8) It would be nice to have a label for the current-set jumper. Maybe a note on the bottom of the board after the "6-36V 333/667mA" eg: "6-36V 333/667mA (OPEN/CLOSED)" Just a thought.

That's it.
