This is a simple breakout board for the nRF52840 Minew MS88SF2 module.
Solder all components except the module. Clean PCB.
Test if 3V3 regulator works by connecting 5V to VIN5V-pin (with 50mA power limit). The board should not use any significant current. Measure the 3V3O-pin, it should be 3.3V.
Now solder module.
Do not forget to connect an antenna if using the MS88SF2-U.FL module.
