FAQ
Is there a fritzing add on/ library available?
This lovely display can't be a shield for the ESP32-WROOM-32, because the "data" pin of the display is attach to the IO10 of the esp32, this particular pin "SD3" is for the SPI flash driver, in order to install the version 0.0.8 of the board package, the display won't work, with older package like 0.0.7 or 0.0.6 the display work fine but the system are more unstable like wifi disconection or cpu halt, I don´t know if dfrobot team are working in a version 3.0 of the display PCB to fix this issue?
