This is a mini version of the D-link F3 flight controller and shares many of the some components and features including a built in PDB. However due to the smaller size this PDB only supports up to 60A, so you can only use 4 x 15A ESC with this board making it better suited to smaller micro quad copters.
FEATURES:
4oz copper & 6-layers PCB
ESC & battery solder tabs in pairs
Bigger solder pad easy to soldering
Gold-plated craft, excellent electric performance
With Betaflight SPF3 target
