Say hello to my little friend! The Helio Spring Mini is pretty much a shrunk down version of the Helio Spring. It has all the features of the full size Spring, just in a 20x20mm board.
The board I have in this video is a pre-production board so some things may change on the final version.
Highlights
Dual F3 and F4 processor
BetaFlightOSD
5 Full UARTS
Supports all receivers with multiple 5v and 3.3v outputs
UART1 and 2 have inverters for S.Bus and SmartPort telemetry
supports DSHOT and MULTISHOT
can be powered directly off the battery up to 6s
LC filter on the OSD and camera power out
The Helio Spring Mini was built with the EMAX 35A 4in1 BLHeli32 ESC. The build was super easy as with the full size Spring. Just rearrange the harness so vbat/ground matches and remap the motor outputs. With 5 UARTS to use, you can pretty much connect whatever you want on the board. Crossfire was hooked up to UART5 and SmartAudio on TX3.
I tried the latest version firmware which was I think 3.6.2 but it didn't recognize any of my motors. Only got half startup chime and all the motors were greyed out in the motors tab.
Since this is a hardware review and not firmware, I went with a firmware I know works, 3.5.1 and everything worked great. All I changed were the rates and left everything on default including PIDs.
It flies great! It has the buttery smooth feeling that I love from the full sized Helio Spring. Even on default PIDs there were no signs of any oscillations or prop wash no matter how hard I tried.
If you like the Helio Spring, you'll love the Helio Spring Mini. This board will be available soon.
If you found this post helpful, it would be super cool if you purchased the components from my store or purchase items from my Amazon links. These posts are expensive and take a loooong time to make so the purchases make it possible for me to keep making them. Thanks in advance, I greatly appreciate it :)
