On a well-known Chinese site, such a miracle is offered to access the GY-MCU90640:

Most likely, there should be some description of the interaction protocol with the microcontroller installed on the board, according to which this software product works! After a brief conversation with the seller of scarves (respect to these respected gentlemen), such a protocol was sent to me. It appeared in pdf and pure Chinese.

Thanks to Google’s translator and active copy-paste, after about an hour and a half, the protocol was decrypted, anyone can read it on Github. It turned out that the scarf understands six basic commands, among which there is a frame request on the COM port.

Each pixel of the matrix is, in fact, the temperature value of the object that this pixel is looking at. The temperature in degrees Celsius times 100 (double-byte number). There is even a special mode in which the scarf will send frames from the matrix to the Raspberry 4 times per second.
