DALRC Engine 4-in-1 40A ESC
#1
The cover not only Look cool, but also functional as heatsink.
But the long motor wires kind of troubles me, longer, more resistance. But it seems like they are using quite large gauge wires there, but then it's going to weigh a bit more.
Rumour says it's BLHeli32, and has a 5V BEC also.

Looks like the FC can be plugged in directly, so the vibration damping tubes make sense. Will make a clean build.
3A 5V bec - may be able to actuallly output rated amps thanks to the heat sink, I like the idea.

Over 1000 uF caps, they say its is low ESR, but they look like ordinary ceramic caps. This is a render though... but they also suggest to mount at least a 470uf 25V Rubycon cap so looks like the ones mounted on the PCB are not enough.

40A up to 5S pack, 50A burst.
Blheli32
Current sensor included Smile

Longer wires should not be a problem, all 4in1 are like this.

Ceramic capacitors have a very low ESR. Typically in the range of 0.01 to 0.1 Ohms which is far lower than most electrolytic capacitors can achieve.

A small electrolytic or tantalum capacitor can be useful to eliminate any ringing that can be cause by the extremely low ESR of the ceramic capacitors.

I thought SMD ceramic are comparable to regular electrolytic caps, thanks for clarification - a few things make more sense to me now Smile

Would have been nice if they added esc telemetry

Cool!  Cool
Looks a bit like AlienWare!

Is there an FC as well, seems odd to have a connector for one and not release it

I just bought this ESC and it has a current sensor wire, is this the same as esc telemtry and does this connect to a UART on the FC? The ESC also has a 'VCC' and '5V' lead. I assume its leads to power other gear? The manual that came with this item is vague. The website is no help either.

I’m in the same boat, I have the VCC and current wires twisted up and loose until I can find an answer, and is the 5v used needed as well?

I believe the "Current Sensor Wire" has to be connected to the dedicated external "current sensor pin on the FC", which is usually marked as "CURR".
On most BLHeli_32 4in1 ESC's, you can also get the same current sensor info from ESC Telemetry, so you can leave the current sensor unconnected. But I am not sure if this is the case for this ESC. Give it a try and let us know.

Thanks Oscar, it may seem obvious but the diagrams don’t indicate using 5v on the Matek f405. Is this true? I take it that the 5v would be used if you are powering directly to the esc. I now have mine disconnected but am unsure if that’s accurate.

So, Oscar is correct. Curr wire from ESC connects to Curr on FC. And your F405 CTR has a Curr pin next to S2 pin.

F405 CTR takes lipo voltage not 5v. So run a 20ish gauge wire from ESC VCC and ground to the large lipo connector on FC.

Aww nah, another wrench. So I need VCC?

You have VCC off the Port on the ESC. Or just run two wires off the lipo connections.

That what I’ve done, just making sure. Thank you voodoo
