The new ultralight Toothpick F405 2-4S AIO 20A FC is finally released! Compared with the V3 version, the new V4 board updates the F411 chip to F405. It can handle 20A of continuous current and up to 4S! Strong performance lets you break through the limits of your quad and explore more possibilities in the flight. Highly recommend using it on Beta95X V3 and Beta95X V3 HD Digital VTX to get a smooth flight.
Note: The MPU6000 gyro is not available due to rising prices and lack of stock. We decide to change the gyro to BMI270 for the Toothpick series flight controller to continuously provide the product service.
BMI270 gyro works great in most cases, especially in low frequency. But it will need more software filters and is sensitive in high frequency. This can be solved by adjusting filter settings in PID tuning. You can flash our CLI file or set gyro lowpass 2 at 135Hz and choose filter type at PT2 in settings. This will help BMI270 gyro to get a similar performance as MPU6000 gyro. Below pictures show the difference between the two gyros.

Please Note: The chip of F405 V4 flight controller's ESC has changed to AT32F415 from STM32F105 due to shortage. While the AT32F415 is applicable to the ESC firmware version BETAFPV_20A_AT32.
There are 2 LEDs on the bottom of the board to indicate the status, including the Power LED ( Red), FC LED(Blue).

The new AIO board has integrated the Plug & Play Port for the external Rx, and there will be a 4-Pin connector for Rx in the package. Thus, we highly recommend pilots to use pin-connect to save the solder work.
