-add polarity protection FET to the board so we eliminate dirpy dauther card
+replace USB connector with a version that has actual slow primitive (which
+means moving to latest pcb-rnd 4-layer template)
-need to move DIP switch away from mounting hole, actual switch is larger than
-the current silksreen rectangle and makes putting that nut on nearly impossible
-
-transfer LED color indications to the other side of the PCB
+fix the short that's apparently been there a while? v_lipo to ground?
possibly thermally relieve the battery negative 0.25" spade
