You can power your badge via either USB C, or a (flat-top) 18650 lithium-ion battery. Its USB does not require USB PD, and you can plug it into any USB 3.0 computer or (phone) charger. If you use a li-ion battery, the positive end should point towards the USB connector. The battery will charge when USB is connected.
First time boot
When you power on your badge for the first time, you are greeted with a special boot animation. It’s on the highest brightness at this point, so be ready..!
