## Introduction
|
||||
This ESP32 Arduino/IDF library for HUB75 / HUB75E connector type 64x32 RGB LED 1/16 Scan OR 64x64 RGB LED 1/32 Scan LED Matrix Panel, utilities the DMA functionality provided by the ESP32's I2S 'LCD Mode'.

- Refer to [this comment](https://github.com/mrfaptastic/ESP32-HUB75-MatrixPanel-I2S-DMA/issues/35#issuecomment-726419862) in regards to certain panels not playing nice with voltages, and a 3.3volt signal that the ESP32 GPIO can only provide.
