CM4 IO Case For Raspberry Pi Compute Module 4 IO Computer


One-Click Switch

The one-click switch is to control the system power on and shut off by GPIO3 on a 40pin connector & the software running on Compute Module 4.

Hardware Protection

The case perfectly fits the mechanicals of the Raspberry Pi Compute Module 4 IO Board, and all interfaces are led out of the enclosure.
The metal case provides excellent shielding and protection for Compute Module 4 & IO Board.

Fix Compute Module 4

The four nuts at the bottom of the case can help to fix the Compute Module 4 on the IO board & case reliably. There are four 1.5mm height black nylon washers to support Compute Module 4 on the four corners of the PCB. This feature prevents PCB deformation and circuit damage when the Compute Module 4 is screwed on the IO board without
something to support.

Cooling Compute Module 4

A 12V/60mA silent fan is installed directly over the Compute Module 4, which is isolated from the case by four silicone washers, these silicone washers greatly reduce the noise magnification by the case. The fan can reduce the CPU temperature by a maximal 20°C and heat generated by the whole system is dissipated by the fan through the slots at the sides of the case.

External Antenna Raspberry Pi’s officially certified 2.4G/5.8GHz WiFi/Bluetooth Antenna is installed on the case.

Battery Offer Philips CR2032 Eco-friendly to enable RTC function.
Dimension 171.5(L) x 109.5(W) x 28.5(H) mm
Weight 450g
