I posted our open source cubesat design on reddit a couple weeks ago and someone suggested that I also post it here.
We have developed a new hardware system for cubesats that uses a slotted connector instead of the PC-104 stack. It’s super easy to work and still conforms to the cubesat standard.
Feel free to use it on your own projects. And if you find it useful or think it needs improvements please let us know! We would love feedback on the design.
The idea is that anyone can download and manufacture this product for themselves for free, however, we also sell it on our website for near cost if you want to go that route as well.
