alleebell I won't carry it even if it is FREE! It reflects my ignorance of what it says on the bag, Like you said - it has no meaning! 即使它是免費的，我也不會攜帶它！它反映出我對袋上的字一無所知，就像您說的那樣-沒有任何意義！

alleebell I suggest setting the resolution of the HDMI to 640x480. Then change it to a higher resolution.

alleebell D1 and D2 are internally wired for the OLED and it is not accessible at the header. I suggest using D3 and D4 and use the wire.begin(D3, D4) to declare it.

alleebell I bought four modules recently. None of them worked at described by other users. They are useless! I used the FastLed library and the "blink" scratch to test one LED at a time with R, G, and B color per LED. I cannot get one board to display one color with all 64 LED. Junk!

alleebell I received four last week. I used WS2812 strip before. I am not able to get even one module to work correctly with Arduino nano. I am going to do more research before I contact Customer Support. based on what I read here, this product has reliability "issue".

alleebell I wish the description of this kit tell us where DHT-11 and the OLED are connected. My finding: The DHT-11 is to pin 5. For the OLED, SDA is to pin 2 and SCL is to 14. The OLED is SSD1306 (it is on the package).
