Hi everyone,

I'm relatively new to electronics, ICs, and PCB design, and I'm currently working on a drone project. I've come across an integrated circuit (IC) that I believe could be perfect for my needs, but I'm having trouble finding detailed information about it.

The IC is an 8-bit microcontroller with a built-in RF transmitter, which I've learned is quite popular in remote controllers and toys. However, my searches for its datasheet or even its real name have come up empty so far. The IC has the following printed names on it: PAN186CV and RF250A.

From what I understand, identifying and sourcing specific ICs is crucial for ensuring the right fit for projects, especially for someone like me who is just starting out and eager to learn more about the components I'm working with.

I would greatly appreciate it if anyone could help me identify this IC, point me to its datasheet, or share insights on its functionality and application. Additionally, if you could guide me to the right places or websites where I could source or unlock this IC, that would be incredibly helpful.

Thank you so much in advance for your time and assistance. I'm really excited to dive deeper into the world of electronics and make progress on my drone project with your support!

Where did you get that information from?

I can't see any RF circuitry on that board - resonant circuit, antenna etc. It may be a bluetooth device - quite likely in fact.

What is the original function of the board? I know it's a 'game' controller but is there anything else associated with it?

All that aside you will probably be unable to source the component anyway so you'd be far better off finding something more generic. You can get blue tooth modules quite easily. There are also ESP32 modules with processors, bluetooth, wifi or whatever you want - such as these:

hello,

i see a very short antenna at the edge of the board.
the chip next to it is probably a kind of synthesizer chip for rf.
i also see a crystal at the other side of the chip.
the type marking has been wiped off to protect the copyright.

Yes! I thought it was a loose wire! Missed the board print too i.e. "ANT" !!! Doofus!.

Anyway, everything else I said fits - ESP32 all the way.

From a search i did and found some people posting and stating that but they couldn't go further.

no it's just simple remote control for a nano drone toy which I'm trying to replicate, which have simple function like taking off, landing, trimming, etc.

All that aside you will probably be unable to source the component anyway so you'd be far better off finding something more generic.
i was actually going for a trip to China very soon, and i was wondering if i could get some information on hands before so i can at least work on my board before arriving there and try to source the component.
