Ian Tester / Qwiic power injectors - History

LiFePO4 14500 power: more rearrangement, making board smaller

Move protection circuit up to fit between D2 and the switch.
Have +Batt connection to the switch run under D2.
Run connections to the dual MOSFET using vias on the back.
Move LEDs to edge of board.
Use 0.3 mm vias to be compatible with PCBWay.

LiFePO4 14500 power: more rearranging of D1, D2, and L1

LiFePO4 14500 power: fix some silkscreen labels that somehow ended up on the paste layers

LiFePO4 14500 power: lots of changes

Trim width of board to 14500 battery holder.
Remove one Qwiic connector.
Adjust layout of D1, D2, and L1.
Change L1 to 18 uH part.
Move C3 to other end of line of parts so that the Batt+ connection from U1 can be shorter and R5 can move closer to U1.
Move LEDs a little further away so C6 can fit better.
Adjust width of several tracks.

LiFePO4 14500 power: made the two connectors and switch fit

Mostly done?

LiFePO4 14500 power: mostly laid out, still need to make the Qwiic connectors and power switch fit

LiFePO4 14500 power: more work on layout on components and their silkscreen labels
