Tact switch (button) board 12.2mm diameter. White silkscreen rings are 10mm and 11mm. Semi-universal pads. Accepts 4-pin 4×4, 5x5, 6×6mm smd switches and 2-pin 3x6mm switches (diagonally). 4-pin switches can be oriented with pins up/down or left/right. Standard 2.54mm header pins surface mount on the back.
Should be resistant to water entering the driver cavity if set in place with RTV silicone sealing the board edge. Solder over the vias on the back. Use Neutral cure silicone (aka non-corrosive or sensor safe).

CREE XB 16.0mm star. For Cree XB leds. XB-H, XB-D, XB-E, XB-G. White silkscreen ring is 10mm.
Each via should be filled with solder or, even better, a short piece of solid copper wire + solder.
Be aware oshpark pcbs are FR4 (flame retardant fiberglass), far from ideal for high power leds like XB-H. Led stars are normally MCPCB (metal core pcb). Only order this board if you can’t locate a proper MCPCB Cree XB star.

4 x AA serial battery carrier. Bottom plate. 12 awg solid core wire should fit through the vias. The bottom side of all vias really should be covered (kapton, packing tape, epoxy etc). At very least the via for the positive connection must be covered.
