Using the Öchìn board to fly Open.HD on a wing
108Today we're using the Öchìn board to fly with Open.HD on a wing. This video has been quite some time in the making because of various setup issues I had, so let me run you past everything we found and how we fixed them.
If you want an Öchìn board, you can now buy one direct from Seeed who are making it on behalf of Flavio: https://www.seeedstudio.com/Ochin-Tiny-Carrier-Board-for-Raspberry-Pi-Compute-Module-4-p-5463.html
For more instructions on setup, schematics on how to build your own board, and STL files for 3D printable parts, check out the Öchìn GitHub page here https://github.com/ochin-space/ochin-CM4
