Its The Brains of This Operation. Omnibus F4 AIO, NeoBlox GPS, HC-12, and iNav.

I’ve decided to scrap the NRF24 wireless transceivers for 433mhz HC-12 (SI4463) wireless transceivers. I have a few good reasons which are beyond the scope of my hexacopter post, and because most people will use a commercial transmitter and receiver. If you are interested in why I have done this, check out this post: HC-12 RC Transceiver.

The major differences between the quadcopter and the hexacopter are obvious. 2 more motors, and 2 more ESCs. However, the additional motors forced me to find a new PDB. Fortunately, I found one that has a 30mm hole spacing. I’ve also upgraded the FC to an Omnibus AIO F3 which also shares 30mm mounting hole spacing and can run iNav. The neoblox GPS module I am using also has 30mm hole spacing, so my electronics stack should be nice and compact. Check out the parts list, and assemby photos below.
