Testing and Repairing 3 USB-C Connectors

This step is done after the bootloader is flashed to the chip. With the bootloader enabled, we will see if the computer detects the nRF52840 chip. If the device doesn't connect or if the device is not recognized, it's likely that the data lines on the USB-C connector are not soldered properly.
