The size is tiny. it’s not just an FC. It’s also a PDB
This FC is designed for the micro femtoquad. It’s 20mm by 20mm and has no mounting holes.
Thus you’ll have to mount it using double sided tape.
Which honestly is a good thing because that’s an effective method of soft mounting a FC anyway.
The FC even has an LC filtered 5v regulator for your camera and VTx which is outstanding given it’s size.
It’s also got LED and buzzer pads, VBat, and is capable of using 2-4s LiPo batteries.
This FC should be perfect for those sub 150mm sized micro quads (which don’t produce much noise, to begin with).
