Hello,i  received from BG a couple of days ago this esc;FVT CloudPhoenix 12AX4 12A BLHeli_32 3-4S ESC
It is a Blheli32 es 4in1 12A 3/4S esc with 20x20mm mounting hole.

https://www.banggood.com/FVT-CloudPhoeni...rehouse=CN
It comes in a antistatic bag with scratch-off label to check on szfvt.com if ifake or not.(it is genuine) and a 6wire silicon cable with jst plug and 75mm 18AWG batt wires.
The quality of soldering seems ok but the mounting hole are really close(almost flush) to components.


Ther are NO manuals/scheme/specs/qrcode included or downloadable on svfvt.com.
Wich is the color code?
I wrote today an email to fvt and to Bg asking to update product page and i am waiting response..
There are just 6 wires:4 motor signals and a 1 black and 1 red wires so no telemetry.
But the red and black? there are no Becs onboard so it is Vbatt? No ! i checked(without motors and a smokestopped 3s lipo) with multimeter and i read 0.00?!?!
The motor layout is a bit strange also for me...

Anyone may help me?
Thanks Lorenzo

Can you try checking without smoke stopper?

That's really poor.

I guess the reason why they never showed pictures of the back of the ESC is that people might (quite rightly) ask how they're supposed to mount a board with 3mm holes and components that go right up to the edge of the hole.

The motor order isn't logical. It's certainly not Betaflight order, but then again, you can just ignore the numbering and wire each motor to the closest set of pads. The first four wires on the 6 wire socket will be the motor signals, so it's just a matter of testing which wire is which and then connecting them to your flight controller in the right order.

If they've done things correctly, I'd say that the red wire should be the telemetry output. If that's the case, you should find that the red wire makes a connection to a pin on each of the microprocessors on the top of the board. You should be able to buzz that out with your multimeter.

Why?

Checking with multimeter, i found that between the black wire and the signal wires it displays 3.3v but with red just 0v...if the red is a signal why there are no V readings on the multimeter?
It is impossible to check ten pins on the microprocessor with my beefy multimeter probes...

I found that sometimes when I have the smoke stopper on, the regulated voltage doesn't always work probably. I know you say that the ESC does not have a BEC, but it is worth ruling out.

The spec does say it has telemetry. On a photo I saw from Banggood, there is a white coming out between the lipo red and black. Looking at your photo, I can't figure out where that white wire is coming from.

Lastly, I remember seeing somewhere that you can figure out the telemetry pinout. I will see if I can locate that post. Then you can test if one of the two mystery wires is telemetry.

Check this pin to see if it has continuity with either the red or black wire. That is your TX pin for telemetry. 

I also wonder if one of the wire is current sensor? Current sensor output will give 0v-3.3v.

There seems to be 4 small current shunts on the board.

And telemetry output gives 0-3.3v too?

It's a logic signal rather than a voltage, but it probably would go from 0V for a zero and 3.3V for a one.

If it is the telemetry output, you won't see it with a multimeter as the signal would be constantly moving from 0 to 1 as it sends the data.

 checked with mulimeter: no continuty between the tx pad and red or black

Well, at least you know where the telemetry output is now. Just ignore the red wire. It's a bit silly that it's not connected to battery voltage though as that means you'll have to run two extra wires - one for telemetry and one for VBAT.

The red wire certainly won't be a current sensor output. As there are four current sensors, the only way they would be reported back to your flight controller is via telemetry.

Can you see if there is a track leading to the pin for the red wire? Maybe the pin isn't connected to anything at all?

If it isn't actually connected to anything, you could use a fine wire to connect it to the battery voltage anyway. Of course, you'd have to be absolutely certain that it isn't connected to anything before doing that or otherwise the magic smoke will escape!

HI all and thanks. I decided to try that new CLRacing F4 mini. Bummer is, it has not buzzer.

Anyway, this 4 in 1 with no paperwork or pinouts:

This is to confirm that ESC telemetry does, in fact work, very well. This pic above denoting the red circle is the correct Telemetry pad and it does provide motor RPM and Temp when connected to an RX. I deployed an XT30 Umass for Voltage sensing and Amperage draw and it all works very nicely. I was forced to connect an extra wire to power the FC. Vbat via the lipo pos lead terminal on the esc. The ground is the black wire in the ESC harness. The Red wire does nothing so, the info above regarding that red wire is/was a correct assumption. I have no idea what they intended that red wire for but, it is not ESC telemetry nor, is it Vbat. . See the red circle above for that ESC telemetry location.

Cheers! And thanks to you all who got me here ! You guys rock!

Thank you Steve. I am waiting the Weller gets hot to connect the tx pad right now!!!!

Done! Soldered a 30awg wire form tx pad to rx on fc and it worked perfectly. Now in osd is displayed temp and rpm. May it measure current also?
