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 unit or 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 toothpick drone,this new AIO Brushless FC can handle 20A continuous current(25A burst), which is the first 20A All-in-one FC on the market. Compared to FC / ESC Stacks design, this board provided with 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 is your best choice to DIY your own toothpick drone that is tailored to your requirements.
This new board can handle 20A continuous current(25A burst), which is the first 20A All-in-one FC on the market
Comes with 4*Motor Pluggable Pins and Not Pre-solder in default, fits your needs of self-assembly best
Compatible with 120X, 130X, 140X motors, and 1505 motors
USB port is mounted on the side, you have 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 to solder
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 of Toothpick 12A AIO FC and Toothpick 20A AIO FC
Integrated 24 single N-channel MosFETs chips on 20A AIO FC board, which has a lower inner resistance. 12A AIO FC board adopts 12 dual MosFETs chips instead. Current sensor included.
Double-sided Motor Solder Pad
Support connect with motors via connectors or solder directly
