A USB‑C connector makes programming simple in the Arduino IDE, while the 16 MHz clock, 32 kB flash, 2 kB SRAM and 1 kB EEPROM give you headroom for complex sketches. At just 44 × 18 mm and 30 g, it fits perfectly in tight spaces—and with 14 digital I/O (6× PWM), 8 analog inputs and 40 mA per pin, there’s I/O for every interface.
