    Great build quality and works great and easy when you know the controller is a "ST7920". I used it for my energy node to display the values from my wireless sensor nodes. SPI (serial) worked great, on the internet there is a lot of information about this product!


    The only problem I had is that the screen should run on 3.3 volt (between 2,7 and 5,5v according to the specs). When I run the screen on 3.3V the brightness is to light to have a good view. I'll tried a POT (10K) to fix this but I had no success. Now the processor is running on 3.3v and the screen at 5v. That works great!


    Delivery was fast. (in about 15 days), packaging was good and the product worked as suspected.
