For the recommended battery type and installation instructions for nice!view displays, please refer to the guide available at .
If you have a nice!view version, you can check if the screen works, before soldering the battery wires.
The screen should turn on when there is a USB connection. But the slave side might not trigger key presses.
If you want to quickly test the keyboard, you can solder the battery wires onto the bottom side. But this is not compatible with a tight 3D printed case. You will need a thicker case or a sandwich case.
It's recommended to turn off the keyboard first.
Solder the battery wires one by one according to the polarity. Never short the battery wires.
