A number of weeks in the past I reviewed the BetaFPV Pavo30 drone that was based mostly on this Toothpick F722 flight controller. Due to some accident, a number of of the MOSFETs on the board fried and I made a decision to order a brand new one.
In a nutshell, a flight controller (aka FC) is the mind of the drone. Its central processor receives knowledge from a variety of onboard sensors (Gyroscope, Accelerometer, Barometer, and Compass), in addition to pilots’ instructions, and controls the pace of every motor instantly or by way of an ESC to make the plane transfer as instructed.
The BetaFPV Toothpick F722 is a flexible and highly effective flight controller designed for 3-5″ quadcopters (it has 4 motor outputs). It can be utilized on CineWhoop fashion drones in addition to on Thootpick ones. Thanks to the six UART ports, will be interfaced with a variety of gadgets, reminiscent of GPS, LED boards, VTX, and FPV digital camera.
BetaFPV Toothpick F722 assessment
Disclosure: I obtained this flight controller as a part of a product assessment collaboration with BetaFPV. Technical specs and high quality could differ in line with the producer’s reliability, so I can not assure that you’re going to get a product that’s similar as seen in my article.
The Toothpick F722 flight controller is available in a pleasant plastic field with 14AWG silicone XT60 energy cable, RF filter capacitor, 6-Pin Connector for DJI Digital VTX, and mounting equipment (4 items of M2x10mm screws with nuts and silicone grommets) included.
The board measures 33x33mm and it has a 25.8×25.8mm mounting sample. The arrow close to the STM32F722 high-performance CPU signifies the set up course of the FC. It has massive soldering pads for motors and protected house between battery wiring holes. Additionally, you’ve gotten devoted holes for the 470uF 35V capacitor. There is a regular micro USB port for firmware improve and configuration.
Near the MPU6000 movement processing unit (3-axis gyroscope + 3-axis accelerometer) there are two standing LEDs (Power and Mode).
Its built-in BLHeli_S 4-in-1 ESC is rated at 35A with 40A peeks. It has six (3 on either side of the board) TPN2R304PL MOSFETs for every channel.

Wiring pinout (wiring diagram)
The BetaFPV’s Toothpick F722 AIO flight controller has battery enter (+-), 4 motor outs, 2×5 pin raws (TX5/GND, CAM/5V, VTX/LED, GND/BUZZ+, and 5V/BUZZ-), and a 5/6 pin pads (3.3V, TX3, 5V, GND, RX1, and TX1 / GND, 5V, RX3, 5V, GND, RX6, and TX6). It additionally has a 6pin connector for DJICaddx digital VTX (SBUSRX3, GND, RX2, TX2, GND, and BAT+).
Price and availability
Priced for $84.99, it isn’t the most affordable flight controller proper now. It has virtually half the value of a drone that comes with the F722 AIO 35A FC onboard. You can order it instantly from BetaFlight or different fashionable RC interest retailers.
- Price/efficiency ratio
- UART Ports
Personally, I like the all-in-one design as a result of it’s tremendous compact when it comes to dimension, it has decreased weight, requires much less soldering/wiring, and theoretically is extra economical. However, if something burns out on an AIO flight controller, you’d have to exchange the entire board, which suggests the FC in addition to all of the ESC’s, and that may be fairly costly.
