Description Features: The UNO R4 is now a 32-bit Microcontroller board, being previously based on 8-bit AVR. The board features 14 digital I/O ports and 6 analog channels. Dedicated pins for I2C, SPI, and UART connections. It has a significantly larger memory: 8 times more flash memory (256 kB) and 16 times more SRAM (32 kB). Fastest 48 MHz clock Speed. It is 3x faster than its predecessors. Onboard ESP32-S3 module for Wi-Fi Bluetooth connectivity, Onboard 12×8 LED matrix: Making one of the most visually unique Arduino boards to date. The LED matrix is fully programmable, where you can load anything from still frames to custom animations.
