-## TODO
-
-Problem | Solution
----|---
-Add CR1220 holder | No. pads are too big, and it's possible to solder on CR2032 thru-holes.
-Always use voltage regulator after battery (helps with 2-battery packs)? | No, could drain extra power.
-Add switchable power source (shottky-based) | Yes. USB or SWD must turn off the battery power source when connected.
-Add reverse battery protection mosfet | No. Better use solder jumpers to fix board assymetry.
-Make YJ-14015 mounting area detachable (tearable) from the board in case we don't need it | Maybe.
-I2C slot overlaps SWD slot, how to connect both display and SWD ??? Fix the overlap? | No. You don't really need that since there's no realtime debugging anyway.
-Add mounting holes for people that cut acrylic cases | Fine.
