Arduino is an open-source electronics platform based on easy-to-use hardware and software. Arduino boards are able to read inputs - light on a sensor, a finger on a button, or a Twitter message - and turn it into an output - activating a motor, turning on an LED, publishing something online.

A tiny and lovely clear acrylic enclosure for the raspberry pi zero. It designed to be beautiful, light, and easy-assembly. Perfect for any use (but especially for those who want to carry their Pi around in their pocket!). This enclosure is only compatible with the Raspberry Pi Zero! The case is as minimal as it gets coming in just two pieces of acrylic that secure with four screws. Made of crystal-clear acrylic, this case keeps the Pi Zero secure.
There are two USB holes and one cooling hole, you can use all of the connectors on the edges of the Pi: mini HDMI, micro SD slot, micro USB power, and micro USB port. There's also a cut out to allow a 2x20-pin header to be soldered onto the Pi Zero.

This case is also available in black

Features

• Easy to assemble
  
• 2 layers, 4 bolts, spacers and nuts included
  
• Will fit Raspberry Zero & Zero 2

Notes

Only includes the case. RPi Zero is not included.
Don't forget to remove the protective film from the acrylic.
