The BetaFPV Toothpick FC 12A is another great AIO board (FC+ESC) for any toothpick or tinywhoop that you will like to build.
It is a board that could handle LIPO from 2S-4S, so you can use it with a lot of motors (probably not more than 1404), up to 12A per ESC (15A in peak).
BetaFPV did two versions of this board, one more for Tinywhoop and another one more for Toothpick. My advice is to go with this latest one described in this article. You will be able to use it too for tinywhoop/toothpick and the layout is really better.
You will be able to choose to if you want to have the motor pins soldered or not, and they will provide you the FC with an XT30 + capacitor, screws, anti vibration and spare motor pins if you have the non soldered version.
This board contains all extra things that you could need:
- buzzer pad
- led pad
- SBUS / F.Port
- two UARTs
- Extra GND/5v to allow to power up camera/vtx/led
- 3.3V pad if necessary
- Built-in current sensor / OSD
You can cut down the corners of the FC if you wish to use it in a classic tinywhoop.

The first thing that you will see with this FC is how well everything is correctly soldered and the quality choosed. It is really perfect and the layout from Kabab is really good. It is easy to solder the wires and you don’t need to be super skillz for that.
The pad of the motors are super accessible, as all extra pad for the receiver/vtx/camera etc
But what is the main difference against other and similar AIO FC ? It is always a question that I’m getting and to be honest it is not super simple to answer. All the FC boards that I tested was great like the NamelessRC FC AIO.
But one big difference to some other board is that they use much more high quality elements like high voltage MosFET to drive the ESC. It seems to improve the latency of the communication with the motors, so if you are looking for such things it is a board that you need.
This board is a really please to use in a custom build and I will detailed that in another article with a step by step guide to build your toothpick.
Here an example of a flight with this board:
