BrainFPV RE1 FC Race Edition
#1
BrainFPV released their 2nd flight controller, specifically for racing. It's still a F4 FC, but unfortunately it's not being supported by Raceflight or Betaflight yet.
The creator of this FC seems to be avoiding these most popular firmware/software, and chose to support dRonin, a OpenPilot/TauLab like software.

It has built-in OSD like the previous version, but it's no longer the only FC with built-in OSD, EMAX is doing it as well now on their F3 FC.

I just wish this FC get supported in Raceflight and support for Multishot/Oneshot (I don't see this mentioned anywhere)

I like it the fact that it uses all header pins and not fragile plastic connectors.

It's also has dedicated solder pads for IR transponders, which is used in racing.

You can get the dedicated PDB with it, which provides power for the FC, as well as giving voltage/current reading for the OSD/telemetry. it also provides 5V/12V power for FPV gear.

There is a test file in the works for betaflight on the re1. I've already tried it and am stunned by the re1's capability. Martin should have the new target ready for this weekend hopefully. I'm sure the other *flight forks will follow suit.
If it isn't broke, fix it anyways!

i was just looking at this fc. looks promising, had a stackable pdb. it's a little pricey at $80 but would be worth it if does everything it says it does.
