Toothpick F4 2-4S AIO Brushless Flight Controller 20A(BLHeli_S) (Version 3)

The V3 version has all the function of V2 board, also add the following 2 additional function.

• Add 8M Flash chip for Betaflight Black Box.
• 3 full UARTs (UART1, UART2 and UART6) are available in the V3 version. Pilots could use one UART for DJI digital FPV unitor Caddx Vista digital FPV unit and the other UART for external receiver like TBS Crossfire.

The V2 board only have one full UART and could not support DJI digital FPV VTX.

For a new generation of toothpickdronethis new AIO Brushless FC can handle 20A continuous current(25A burst), which is the first 20A All-in-one FCon the market.ComparedtoFC/ESC Stacksdesign, this board providedwith massive levels of performance capability while still maintain ultralight only 6.63g.Breaking through the limit of toothpick power, exploring more possibilities in 3”-4” drones. This board isyourbest choice toDIY your own toothpick drone that is tailored to your requirements.

BULLET POINT

• This new board can handle 20A continuouscurrent(25A burst), which is the first 20A All-in-one FCon the market
• Comes with 4*Motor Pluggable Pins and NotPre-solder in default,fitsyour needs of self-assembly best
• Compatible with120X,130X, 140X motors, and1505 motors
• USB port is mounted on the side, youhave more possibilities of mounting it while still maintaining access to the USB port
• All of the solder pads are at the edge of FC, which is a convenience tosolder
• Double-sided motor solder pad. Pins pad and wires pad are both built-in for motors connection
• Integrated with a Betaflight MATEKF411 processor FC, Betaflight OSD,F4 MCU,and 20A ESC,support 2-4S battery

Comparison ofToothpick 12A AIO FCandToothpick 20A AIO FC

PARTS UPDATED

• Integrated24 singleN-channel MosFETs chips on20A AIO FC board,which has a lower inner resistance. 12A AIO FC board adopts 12 dual MosFETschips instead. Current sensor included.

Double-sided Motor Solder Pad
Support connect with motors via connectors or solder directly
