LED - 9. RGB LED Matrix Drive with ESP 32 without shield
" ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth . The ESP32 series employs a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations and includes built-in antenna switches, RF balun , power amplifier, low-noise receive amplifier, filters, and power-management modules. ESP32 is created and developed by Espressif Systems , a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process. [2] It is a successor to the ESP8266 microcontroller. " <from https://en.wikipedia.org/wiki/ESP32 > ESP32 is a Dual Core MCU The predecessor of ESP32, the ESP8266 has a builtin processor. However due to multitasking involved in updating the WiFi stack, most of the applications use a separate micro-controller for data processing, interfacing sensors ...
