The latest iteration of the Arduino Uno is out, the Arduino Uno R4. As the successor to the Uno R3, the new board uses a 32-bit Arm Cortex-M4 CPU alongside an ESP32-S3 which provides Wi-Fi and Bluetooth connectivity. Add USB-C, a 12-bit DAC, and a 12x8 LED matrix then this just might be the best Arduino ever! --- Let Me Explain T-shirt: Twitter: Instagram: #garyexplains
