Awesome 90 frame (decided to chop the front off to save weight) from Banggood along with Racerstar 10,000kv 1103 motors, 6A 1-2S BLHeli_S ESC's with Gemfan 2035 PC props and the pepperfish.de clone FC/Rx.

Also has a butchered 3D printed mount for the Eachine EF-02.

40g AUW and 61g with 1S 750 Nano-Tech battery! mile:














This thing flys damn quiet...

Excellent Pictures and great build! That thing looks mean

Hi Jimbo,

As I see you have a buzzer on the FC. Does it work properly? I have the same clone board but the buzzer doesn't work properly. It's beeping during the power up but cannot activate it with switch although BF config is ok. Another issue it beeps constantly when I switch to acro mode.

regards,

Sounds like it's flashed with the wrong target or the cloners didn't copy pepperfish's design properly.

I think the board arrived with 3.1.5 and had this buzzer issue. So I updated BF to the latest but nothing changed. So I think you are right they didn't copy the design properly...

It's not just down to the release of Betaflight. Some boards identify themselves incorrectly and this leads to flashing the wrong target which causes odd stuff like the beeper going off when it shouldn't. For example, see this thread: http://intofpv.com/t-beeping-when-horizo...4-st32f405

An F4 flight controller that almost worked with the REVO target, but like yours, it sounded the beeper all the time while in acro mode. Flashing the AIRBOTF4 target solved the problem.

As far as I understand it, the board in question here is the TinyFish clone with the onboard FrSky receiver. If so, are you flashing it with the TINYFISH target?

Yes it's a TinyFish clone and I flashed with TINYFISH target.

@oleeg - Yep, same issue with mine on TINYFISH BetaFlight target.

Beeps on power up and only stops in Horizon mode...

Slightly annoying and hope there's a workaround in the future!

I think one LED and the buzzer outputs are mixed up. As far as I can remember my other FCs use a LED to display the mode selection (acro, stable). I set low battery warning in BF for this tinyfish FC and I can see when the battery voltage reaches the configured threshold (I see the battery voltage via telemetry) one LED starts blinking. So when I change the mode to acro the buzzer is activated instead of the LED and when the battery voltage reaches the warning threshold the LED is blinking instead the buzzer is beeping...

I just looked at the current schematic for the tinyFISH and the target definitions for Betaflight 3.1.7 and there would appear to be a disconnect between what the circuit diagram says and what the target definition says.

The circuit diagram says that pin 4 (PC15) of the STM32F303 processor should be connected to the gate of the FET that drives the buzzer. The target.h file in Betaflight defines the buzzer as being on pin 20 (PB2), which isn't connected to anything in the circuit diagram. The target also defines LED1 as being on PC15, whereas the circuit diagram says it is connected to pin 34 (PA13).

So, if you make a custom build where BUZZER is defined as PC15 and LED1 is defined as PA13 to agree with the circuit diagram, things might start working as expected!

Well I found the TINYFISH target.h so modifying the buzzer and LED1 pin is OK but building/compiling a custom firmware is all Greek to me...

I'll see if I have the tools installed on this machine...

I accept no responsibility if it blows up your flight controller, causes impotence, makes your friends stop talking to you, etc, etc.

What could I say unseen? Thank you so much sir!

Need some time to check it because I removed the buzzer but I will inform you about the result.
