New Raspberry Pi formfactor

For anyone interested who missed the announcement, the Raspberry Pi foundation has announced their new ‘Compute Module’.  It’s a full Raspberry Pi in a formfactor very similar to a laptop memory card.  All of the interfaces and power and everything is access via pins and it’s designed for people wanting logic in custom PCBs without the full size/bulk of the original RaspPi.  The article says they’re targeting a $30per at 100 units which should scale up to a final individual price comparable to the Model-B.

There appears to be more IO exposed and it has 4GB of bootable flash built in to further reduce size.

The Raspberry Pi increasingly appears to be a disruptive technology because of the sheer scale of production and low cost/well supported computing.

So fellow Eugene Maker Space folks, if you’ve got ideas for projects or products that would benefit from real computing power and not being tethered to a full sized computer, this may be worth investigating.  Cheap real computing + accessible IO and a healthy software ecosystem can be exciting for the type of innovation where hobby, imagination, and technology intersect.


I needed to quickly fabricate a device for letting me use my ladder sideways on the stairs. I wrote it up on one of my sites here if anyone is interested:

For anyone in a hurry, here’s a pair of pics showing this simple method for solving this problem:

It’s not complicated, it’s not going to change the world, but it sure helped to have a nice little shop to go from concept to execution to not-dead-of-a-broken-neck in just a few hours!
