The Blackmagic Micro Cineme Camera (BMMCC) has a built in expansion port to control operations using PWM, LanC or S.Bus signals. It was originally designed to operate the camera using wireless model remote controls.
The µRemote open source project started some time ago with a result that was not satifying. After a lot of planning I started everything from scratch and built a totally new remote system.
The heart of the system is the µRemote control, a tiny box which is diretly connected to the BMMCC remote port. The case is designed to fit into the small space when using a cage, like the on from SmallRig. The HDMI connector is also accessible.
It has a Micro-USB connector on top for firmware updates and a second Micro-USB connector for accessory control.
All parts and code is under a open source lizense.
