Check out this versatile and high performance AIO flight controller for the micro community. As versatility makes possibility for different builds, depending on what you want out of this board. Pilots can use this AIO board in different builds like agile toothpick or long range quad or creative X6/X8 quads.  

The Poly F405 2S-4S AIO comes with a integrated blackbox, current meter and features 5 UARTs to suit needs for different builds. Apart from versatility, the designers have made this AIO board high performance to make sure it could hold up well on powerful quads. To achieve this goal, this AIO board comes with powerful F405 chip and high quality 20A mosfets and excellent heat dissipation ability.

Note:  if encountering any issues with LED functionality please try the following steps: Go to "Firmware Flasher" tab in Betaflight> Select flight controller "TUNERCF405" > Enable "Full chip erase" > Click "Load Firmware (Online)"> Click "Flash Firmware"

5 UARTs Available | 8 Motors Output | Blackbox and Current Meter Onboard

The Poly F405 AIO board has 5 UARTs available and many interfaces, you can take advantage of them to add external buzzer, GPS module, barometer and etc. Furthermore, this board also features EIGHT motor outputs, definitely a perfect option for x8 quad fans! And for sure, we don’t forget advanced users, 4MB blackbox and current meter are already onboard for Betaflight tuning.


Bluejay is an open source esc firmware. One of the appealing features it comes with is Bidirectional Dshot and RPM filtering, which can improve flight performance a lot. Kudos to devs from Bluejay for their hard work. You can find more detailed information on Github or join their Discord for discussion.


Compared with F405 and F722, F405 has strikingly good performance on flash memory. Since Betaflight is developing fast and packed with more features, the limited 512K flash memory of F411 and F722 is becoming insufficient for Betaflight, the devs from Betaflight have to cram the Betaflight to F411 and F722. The larger flash memory of F405 is good for devs and pilots alike.

Note: “IO” stands for input and output.
