$22 FC product description:

Description:
Item name: F4 Flight Controller
New generation F4 hardware flight controller for FPV race, STM32F405 MCU ,
Frequency up to 168Mhz ,Flight controller firmware is pushing flight controllers to the limit.
Fast loop times enable sophisticated filtering to deliver the locked in, flying on rails feeling.
Betaflight easily delivers 125us (or faster) loop times on the F4 flight controller

Features:
Buzzer Port and LED strip Port
MPU6000 SPI Bus
128Mb Flash(16M Byte)
SBUS/PPM input (Pinheaders)
DSM/DSM2/DSMX input(Plug)
6PWM output (Pinheaders)
Only 36x36mm, mount holes 30.5x30.5mm
All through hole pin header Design -no Sh connectors
STM32 F405 MCU, Runs Raceflight CC3D REVO firmware
Works Perfect with Raceflight - preloaded with Raceflight or BetaFlight 3.0
direct Lipo input :1.5A Built-in onboard regulator - NO BEC needed.
Connect direct to a Lipo to power the board and Rx
RaceFlight or Betaflight support on an STM32 F3 with a SPI based MPU6000
gyro - low noise gyro will not force one to soft-mount the fc

Package included:
1x Raceflight CC3D REVO F4 Flight Controller

I void warranties
Got any more info? I assume the MPU6000 is hooked up over SPI? I also assume the SO-8 iC that's down there by the USB socket is just a SPI flash chip and not a FPU? (Yes it's a big, bad STM32F4 but its gonna be taxed if it has to handle all the math internally)...

What is this a clone of? What board choice do we select when loading cleanflight based FW?


Edited: USB facing the rear... REALLY?! These Chinese "EE" board designers haven't learned that yet?

well you can rotate the board to get whatever USB direction you want, but yeah, I'm hoping banggood releases more details soon

Banggood recently added those specs to their product page as well. However, the type of board it will be recognized as in BF/RF remains unclear.

No vBat?

it's now in stock and the product page has been updated yet again. apparently the board lacks PPM support for some reason... also no VBAT or built in voltage regulation, must be supplied with 5V

Yeah, not sure. I got my from a different source.

It uses the Revo firmware in CF/BF/RF

My supplied pictures are identical also accept mine have a logo on them

Any idea how to obtain vbat and buzzer with this board? I have successfully flashed this board with betaflight 3.0 (previously on raceflight). That would be really helpfull.

Got mine today.

What are they try to hide? (see pic)

I think Ive found the "mother" of this board:
https://nemosminiquadsupplies.com.au...nt=30871626823

It comes from one that has PPM and 3.3V pad. I hope I can get a 3.3V from this one.

The buzzer I think than can use one og those that goes with 3 wires to the ESC conecction. Ill give it a try.

Nice investigation @Miscelaneo 😉

What about inverter for S.PORT telemetry?

This is my board, boot pins instead of a button. 3.3V pads missing. Ppm pad is covered probably because it s not connected somehow. Not a big problem as im using only sbus. Quick look in google and that's what came up https://www.droneeclipse.com/product...ght-controller

Got a 3,3v point from one of the L321 to power my DSM satellite

Got a working buzzer on the sixth conection of the ESC and Betafligth.

This looking good Miscelaneo, any chance of getting a vbat somehow?
