Diagram for F4 1S 12A AIO FC
Below is the diagram for the SPI Frsky version board. UART1, UART2, and SBUS pads are left for external receivers like Frsky XM+, TBS Nano receiver so that a long receiver range is available.
Buzz pads (BUZZ+ and BUZZ-) are invalid directly. It needs some modification to make it works.
Below is the diagram for ELRS 2.4G version board.
The current meter is integrated on the FC board. Here is the configuration in Betaflight Configurator.
12A 1S ESC
Should we really need a 12A ESC for 1S drones? If it is a 65mm or 75mm Whoop drone-like Meteor65, 5A ESC is enough for all actions. But how about with 3" propellers and 1102/1202.5 motors? Still, want smooth and powerful flying actions? The 5A ESC has developed about 3 years ago and was designed for whoop drones with 0603/0802 motors. For the past year, the BETAFPV team has been cooperating with BLHeli author Steffen on the 12A 1S ESC for 3" toothpick drones. Finally, it is here!
It marks "1-2S" on the board, could this FC board support 2S?
NOT Yet. The motor spins not smoothly in 2S power with the released ESC firmware. We will work on it continuously and make this board support 2S later. If you have any ideas or advice, feel free to contact us.
ELRS 2.4G RX
This board integrates the receiver with the most popular radio link ExpressLRS in 2021. ExpressLRS aims to achieve the best possible link performance in both speeds, latency, and range. The serial protocol between the receiver and the F411 FC is the Crossfire serial protocol. Know more about the ExpressLRS project on Github or join the discussion in the Facebook Group.
This board is designed for long-range 3inch ultralight toothpick drones. If you want to try ExpressLRS on 65mm/75mm whoop drones, please stay tuned on our F4 1S FC board with a built-in SPI ExpressLRS receiver.
Come with the build-in SPI Frsky Receiver (CC2500 chip), F4 1S 12A AIO FC can be compatible with Futaba S-FHSS, Frsky D8, and D16 protocol. The default protocol is configured to Frsky D16 FCC out of the factory. Pilots could set up the protocol according to your own need in Betaflight Configurator.
