The item includes the ESP32 module and HUB75 kit.
ESP32 model :ESP32WROOM32
ESP32-WROOM-32 is a powerful, generic Wi-Fi + Bluetooth® + Bluetooth LE MCU module that targets a wide
variety of applications, ranging from low-power sensor networks to the most demanding tasks, such as voice
encoding, music streaming and MP3 decoding.
At the core of this module is the ESP32-D0WDQ6 chip*. The chip embedded is designed to be scalable and
adaptive. There are two CPU cores that can be individually controlled, and the CPU clock frequency is adjustable
from 80 MHz to 240 MHz. The chip also has a low-power coprocessor that can be used instead of the CPU to
save power while performing tasks that do not require much computing power, such as monitoring of
peripherals. ESP32 integrates a rich set of peripherals, ranging from capacitive touch sensors, SD card interface,
Ethernet, high-speed SPI, UART, I2S, and I2C.
The HUB75 kit is a PCB board that links the ESP32 module to the HUB75E socket of the LED Matrix. It is designed according to the project, other projects need to modify the IO PIN definition.(see below)
