Minimize the physical footprint of your permanent embedded projects, wearable tech, and smart sensors with the ultra-compact Arduino Pro Mini. Driven by the dependable ATmega328P microcontroller, this board packs the exact same processing muscle, flash storage, and code compatibility as the standard Arduino Uno, but strips away the bulky onboard USB port and DC barrel jack. Designed for permanent installations where space and weight are critical constraints, it can be programmed effortlessly using an external FTDI or serial-to-USB breakout adapter.
Key Product Features
- Ultra-Minimalist Profile: Weighing less than 2 grams and smaller than a standard AA battery, it easily embeds inside tiny drone chassis, custom jewelry, or compact sensor enclosures.Â
- Optimized for Battery Power: By removing power-hungry USB interface chips, this board features incredibly low power draw, making it the premier choice for long-term battery-operated nodes.Â
- Onboard Voltage Regulation: Features an integrated 5V regulator that safely accepts raw DC inputs up to 12V via the RAW pin, protecting the internal logic.
- Full Prototyping Breakout: Pinout layout includes 14 digital inputs/outputs (with 6 hardware PWM lines) and 8 analog inputs—two more analog pins than a traditional Uno
