Verified Specifications

It operates at 5V logic level with recommended input of 7-12V (limits 6-20V), provides 14 digital I/O pins (6 PWM), 8 analog inputs, 40mA per I/O, 32KB flash (2KB bootloader), 2KB SRAM, 1KB EEPROM, and 16MHz clock speed. Dimensions measure 0.70 x 1.70 inches (45 x 18 mm approx.), with automatic power source selection from USB or VIN.store-usa.arduino+3​

Key Features

Mini USB handles both power and serial communication (via onboard FTDI or CH340 in clones), supporting UART, I2C, and SPI for peripherals. It auto-switches to the highest voltage source, ideal for portable prototypes in your automation projects like sensor nodes or compact PLC interfaces
