How do I find anything about this "microcomputer"?

Disclaimer: You mentioned Arduino. I'm not a fanboy of the ardweenie offerings - I know nothing about them. This in fact may be the golden goose magic socket - but I highly doubt it. Like I may be the Queen of England.

That said, this appears to be a 40 pin socket, a crystal, and just about nothing else. No micro included .. and
VCC outside enlarge 2 road, GND, as shown in figure out the needle.

Whatever the hell that is.

FWIW, the IDE these days is worth far more than the actual hardware - and I see none offered.

IMO, this is worth exactly seventy cents with free shipping and nothing more.
 
""4. Support chips: STC89C52 STC12C5A60S2 STC11/10 x series of AT89S52 and compatible with the chip pins of the chip""

Those are single-chip microcontrollers. The 89C52 probably was derived from older Intel products. Data for all of the listed parts are all over the innergoogle.

I have not read any of the datasheets, so this is a guess:

The 11 MHz clock suggests that the chip has an internal RS-232 format serial port (without the drivers and receivers), but there is nothing on the board for on-board programming. You write and debug the code on a development system, then use a device programmer to transfer the compiled code to the chip, then plug the chip into this board.

Oh, I see.

Thanks for replying! The price of this product seemed suspicious. Guessing they mentioned "support chips" so newbies like me would think there actually is a chip on the board...
 
It's just a breakout board for 8051-derivative microcontrollers with a crystal, bypass caps and an LED. It provides the very basics to get the chip running with headers to access all the pins.
