This case is designed to fit the all-new Raspberry Pi 4. It works with all three variations of the Pi 4 and provides a decent amount of ventilation. The case is comprised of three pieces – a base, midsection, and a lid. With the lid removed, there is also a small slot that the camera can be slid into. The bottom of the case has external access to the microUSB slot and two mounting holes for situations where the case needs to be firmly attached.
