Following on from CC3D, I need a low voltage cutoff on my quad, for the 3S LiPo, as I am constantly running my batteries down to 3% of the batteries capacity.

I’m not entirely sure what the difference is between version 2.1 and 2.2 of the Diatone PDBs, as yet. The RCTech PDB allows for on-board placement of a Naze32 flightcontroller and a Micro MinimOSB.

This, then, led me on to a brief voyage of discovery with respect to ZMR250 specific PDBs.
