Yeah. I tried a project driving 32x16 pixels with a Arduino (an Uno, ATMega328) and it was just barely on the edge of usable for mild animation. Furthermore, I could really only use it at full brightness. These panels are extremely bright, and my project was meant to be desktop display. For the next version, I moved to an ESP8266 which provides plenty of compute speed to drive these panels at a brightness that’s comfortable.
