• USB connector : USB-C
• Built-in LED Pin : 13
• Digital I/O Pins : 14
• Analog input pins : 6
• PWM pins : 6
• Communication Interfaces : UART , SPI , I2C
• Circuit operating voltage : 5V
• Input voltage (limit) : 6-12V
• DC Current per I/O Pin : 20 mA
• DC Current for 3.3V Pin : 50 mA
• Main Processor : ATmega328P 16 MHz
• USB-Serial Processor : ATmega16U2 16 MHz
• Memory ATmega328P : 2KB SRAM, 32KB FLASH, 1KB EEPROM
• Weight : 8.05 g
• Width : 26.70 mm
• Length : 34.20 mm

Noteworthy features include its tiny form factor, a shift to a USB-C connector for power and programming, and a unique black and gold design. Each board is individually numbered, emphasizing its status as a limited edition collectible.

The board’s pin header pitch is 0.05″ (1.27mm), which is half the distance of the classic Arduino UNO, accommodating its smaller size. Despite not featuring a barrel plug connector for an external power supply like its predecessor, the UNO Mini Limited Edition offers two pins for external power sources (VIN and GND).
