Compute Module • Re: Can a CM5 replace a CM4?

Apart from the physical change in the shape of the heatsinking of the main processor, it is basically the same form factor. Some of the parts have moved on the board, but they shouldn’t affect end users.

But electrically, there have had to be some changes, because you’re trying to add new features. So there are some differences which means that it’s not 100% compatible. But for most people it will be a drop-in replacement, and we’re already seeing that people are using it within setups that were designed for CM4 with no problems.

We’ve added new features such as USB 3.0 that won’t work when CM5 is plugged into a carrier board designed for CM4, because CM4 didn’t have USB 3.0. That’s life.

If you want something 100% compatible, stay with CM4; CM4 is still in production and will remain in production for a number of years – 2030-something, and it may well be that we extend it beyond that so it remains available.
