Q: Is this the same thing as an arduino?

Arduino is just a specification for a microcontroller. Although there is an official "Arduino Brand" this model does 100% of what that model does for $5 less. I have a kit that connects every GPIO pin of Arduino, and it connected fine. So for all intents and purposes, this is "the same thing as an arduino."

Q: Ordered two of these and get the same error message: avrdude: ser_open() : can't open device "\\.\COM4": the system cannot find the file specified.

When this happens, I've fixed it by closing the Arduino IDE, unplugging my USB cable from the UNO, plugging it back in, and restarting the IDE. (Save the file before closing the IDE, if desired.) This has always corrected the issue for me, even when the IDE shows an Arduino on COM4 and it's selected yet still seems unavailable.

Q: Does this use the CH340 ?

No. And no. He wants to know the USB chip, not the MCU chip. The USB chip is a CP2021 or whatever, it isn't the CH340.

Q: is the Elegoo compatible with the official Arduino program? (1.8.1 to be exact)

While I have not updated to 1.8.1 yet, I have used it with previous versions with no issues, so I see no reason why it should not work with the latest. I have used 3rd party programs and libraries as well.
