Details of Arduino UNO R4 32-bit board revealed, including the 12x8 RED LED matrix on board and connectivity for IoT applications.

The esp32-hal-ledc.* files provide helper functions to set up the hardware PWM generator, and with these libraries, getting a 16-bit LED fade in straight C or “Arduino” is easy.

An Arduino drives the entire matrix with a single pin. Rather than reinvent the wheel, [Jack] used Adafruit’s NeoMatrix library to drive his display.
