Raspberry Pi Compute Module 4 1U Rackmount Enclosure

# Raspberry Pi Compute Module 4 1U Rackmount Enclosure


# Introduction

This project consists of a [Mini-ITX](https://en.wikipedia.org/wiki/Mini-ITX) adapter and I/O plate to mount the [Raspberry Pi Compute Module 4 I/O board](https://www.raspberrypi.com/products/compute-module-4-io-board/) into the [iStarUSA D-118V2-ITX-DT 1U rackmount enclosure](https://www.monoprice.com/product?p_id=41762). Neither the I/O plate nor the adapter are strictly ITX-compliant; however they are a good fit for the iStarUSA enclosure.

The I/O plate includes openings for all CM4 I/O board connectors; however, the user may wish to remove the 12VDC barrel connector and/or the MicroSD card opening, depending on the use case.

The design requires four M2.5 screws and four M2.5 by 5mm long hex standoffs, with the threded portion extending 3mm. These are used to mount the
