OpenPilot Atom & Nano 30.5 mm mount adapter
This adapter creates a nice surface to mount OpenPilot Atom or Revolution Nano. You can use double sided tape to mount it, or alternatively some vibration damping material of your choice.
Small UBECs fit under the mount. You can also conveniently route wires under it. I have eBay "DC-DC 4.5V-28V to 0.8V-20V Step Down Module" under the adapter, tuned to 5V and locked with a drop of CA glue.
