#There is an open source project on GitHub: ESP32-HUB75-MatrixPanel-I2S-DMA, which has a more detailed introduction.

Working With Pico

Hardware Connection


  • RGB-Matrix-P3-64x64
  • Raspberry Pi Pico (It must be purchased separately. If not, it is recommended to buy one with soldered pin headers, which is convenient for wiring.)

Software Setting


  • After setting up the CircuitPython environment, you can copy all the contents of the CircuitPython directory in the downloaded Pico example to the recognized U flash drive, and you can run the example (there are 16 demos in this code).
  • The PSD folder is a file in ".psd" format, which can be used to modify the text image that needs to be moved. The modified image needs to be saved as "Excellent" and the format needs to be converted to BMP format.

Working with STM32

Hardware Connection


  • RGB-Matrix-P*-64x64 (* indicates the matrix in different pixels).
  • STM32F103RB (Not Included)

Hardware Connection Diagram


Software Setting

  • The demo is based on the HAL library. Download the demo, find the STM32 demo file directory - enter HUB75.uvprojx under the STM32\STM32F103RBT6\MDK-ARM directory.
  • Compile and download. Then connect it to the display, and you can enter the display. (Please make sure the external power supply of 5V 4A is provided; otherwise, it may lead to IO malfunction.)
