Talon F4 V2 and Gigawatt Pinout
Based On 4 reviews.
I got 2 of these bad boys. They meet all the criteria I was looking for plus some. Killed 1, replaced it, then revived original and still got both running in quads. Plan to use couple more in future builds.
A great little (20x20) board! Well put together with a lot of UARTs and a great layout (considering the size - but I do wish all the pads were on the top side), and it pairs great with the Speedix 4:1 ESC that they have on combo (just make sure to change the pinouts on the harness to match). I'm running BF 3.4 at 8k/8k on a 2" build - I have smart audio, Runcam control, OSD, and telemetry all working from it! Lots of function from such a small board. 2 things: no buzzer pads so use Dshot commands to make the motors the buzzer / Telemetry needed to have "set tlm_halfduplex = off" configured in the CLI to work (default state was ON). Overall 5 stars - I'd highly recommend for a micro build!
My new favorite flight controller! The Talon f4 20x20 will definitely be my next fc purchase after this experience. Has all the bells and whistles you would want on a full sized board in a 20x20 with a tight footprint. Flies noticeably better than my other flight controllers even with the exact same settings copied direct through cli dump. I was surprised. Even takes 6s!
So far so good. Got my first three flights in with this new fc loaded with Butterflight and all is good. The layout of the board makes for a easy build. Used the eight pin connector to mate up with a Ori 32. Word of caution though, make sure the connector pins match the esc. I had to change the pins for the Ori. Seems like a quality fc with good layout and construction.
