Over:Board – Raspberry Pi CM4 ITX Motherboard

Over:Board ITX IO board for the CM4

The Over:Board is an IO board for the Raspberry Pi Compute Module 4. It is designed to use a standard PC ATX power connector and features a full size PCI-E 16x slot although its only running at 1x bandwidth and unfortunately it is not compatible with a GPU.

It breaks out the following ports:

  • 24-pin ATX Power
  • 40-pin GPIO
  • Full Size PCI-E @ 1x bandwidth
  • SATA Controller (Powered by USB)
  • Front Panel Header
  • CPU Fan Header
  • UART Header
  • Micro USB
  • RS232 Com Port
  • 2x USB 2.0 Ports
  • Micro SD card slot
  • 3.5mm Audio

The Over:Board costs £199 for an early prototype or £99 for the Final Production board and is available to back now on indiegogo.

Whilst £99 is expensive for a IO board this is likely down to the limited production and it is likely still the cheapest ARM based ITX motherboard on the market even when factoring in the cost of a RPI CM4.

The project currently has £1654 in backing from 11 backers. With 28 days left it is looking likely to hit its £5000 target.

Ross Nicoholls is leading the campaign:

I’ve lost count exactly how many, but this will be about my 35th commercial electronics PCB to be manufactured, so I am no stranger to getting these things to market. That said however, this will be the first of my own venture so represents my most exciting project to date and something I feel very passionate about.

Ross has lots of experience in this field

I wish Ross good luck and hope to see the Over:Board available soon!
