Normal Puck.js devices come with a plain white silicone cover, but in many cases you might want something a bit different. This silicone cover replaces the white case that comes with Puck.js.

This is a black translucent cover with a dark tint. It lets through more light than the standard white case while blending in nicely if you want to place Puck.js on a dark background.

What is Puck.js?

Puck.js is an intelligent Bluetooth button. With the Espruino JavaScript interpreter on its internal ARM microcontroller, software can be uploaded, debugged and modified wirelessly from any modern computer or phone, making development of embedded devices significantly easier. It has built-in sensors, lights, infrared transmitter, GPIO, and can even control other Bluetooth LE devices.
