Versatile and High Performance AIO for Micro Community

This Poly F405 2S-4S AIO is designed for FPV micro community and it’s made to be super versatile, so pilots can use this AIO board in different builds like agile toothpick or long range quad or creative X6/X8 quads. So this AIO board is integrated blackbox, current meter and features 5 UARTs to suit needs for different builds. Apart from versatility, we 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.

Versatility Makes Possibility for Different Builds

5UARTs 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.

High Performance for Better Flying Experience

F405 MCU | FD6288 chip | High Quality 20A Mosfets
With fast 168MHz processing power and 1MB flash memory, F405 chip is a strong core of the AIO board, you could enable RPM filtering or dynamic idle and other features in Betaflight without worrying about if the MCU is overload.
FD6288 chip and high quality 20A mosfets and excellent heat dissipation design make this aio board hold up well for hardcore freestyle flying.

Preflashed with Bluejay

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 

F405 is a good balance in terms of frequency, memory and IO

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.

Note for Firmware Update

You ONLY need to plug in the USB when flashing ESC or flight controller firmware on the Poly. You do not need to plug in the battery. The reason why we recommend doing this is that this is helpful to eliminate the possibility of ESC being damaged during the firmware update.

To be more specific, when the BB21 chip ( the ESC MCU)  is in the process of firmware update, its output pin is out of control, which may cause damage to the ESC.

Note for Receiver and VTX Setup

Please power up the receiver and VTX by the battery during the binding and setup process. Because the 5V from USB does not power the receiver and VTX.

Note for Buzzer Choice

Only the buzzer with a built-in drive circuit can be used on this AIO flight controller. A common micro buzzer (that only has two legs and without PCB board) is incompatible with the Poly F405 2S-4S AIO. We have released the buzzer with a built-in driver circuit. Buy it here.

The Poly F405 board is suitable for lightweight toothpick quads, X6/X8 quads and micro cinewhoops.

To be more specific, any micro builds with 11xx, 12xx, 13xx and 1404 motors are supported by the Poly boards. The maximum motor the Poly board supports is 1404 sized motor.
