From the project

nPM1300 Breakout Board

This is a breakout board for the Nordic nPM1300 Power Management IC.

https://www.nordicsemi.com/Products/nPM1300

In this design, the nPM1300 is configured like this:

BUCK1 disabled BUCK2 enabled, for converting battery or USB input to 3.3V 2 load switches at 3.3V (LS1 and LS2) no LDO 3 LEDs I2C interface

The Gerber file is in this repository (kicad/gerbers/nPM1300-breakout.zip). Simply upload this file a PCB manufacturer of your choice (JLPCB, PCBWay, ...), and you they will make it for you for as low as \$5 for 5 pieces (with the cheapest shipping option, which can take a few weeks).
