## Description

The Adafruit Metro Mini 328 packs the same ATmega328P power as a full-sized Metro into a tiny breadboard-friendly form factor. Running at 16 MHz with 5V logic, it's pin-compatible with Arduino UNO R3 and works with the Arduino IDE by selecting "Arduino UNO" in the Boards menu. For the latest revision with improvements, see the Metro Mini 328 V2. With a genuine SiLabs CP2104 USB-to-serial converter built in, the Metro Mini connects directly to your computer for programming and serial communication — no FTDI adapter needed. It's ideal for projects where breadboard size matters but you still want full ATmega328P capability. Key Features ATmega328P @ 16 MHz – 32 KB flash, 2 KB RAM with Optiboot bootloader Breadboard Friendly – Compact form factor fits standard breadboards Arduino UNO Compatible – Pin-compatible and works with Arduino IDE 20 GPIO Pins – 6 analogue inputs, 6 PWM outputs, hardware SPI, I2C, and UART Built-In USB-to-Serial – SiLabs CP2104 for programming and serial communication 5V Logic (3.3V Optional) – Cut and solder a jumper on the bottom to switch Flexible Power – 6–16V on Vin pin or Micro USB On-Board Regulators – 5V 150 mA output, 3.3V 50 mA available via FTDI chip Four Indicator LEDs – Power (green), RX/TX, and pin 13 (red) Ideal For Breadboard prototyping where space is limited Compact Arduino UNO-compatible projects Embedding in small enclosures and finished projects Learning Arduino programming on a tiny board Package Contents 1× Adafruit Metro Mini 328 (fully assembled and tested) 1× 0.1" header strip (unsoldered) Note: Some light soldering is required to attach the header for breadboard use. Mac and Windows users may need to install the SiLabs CP210x VCP drivers for the serial port to appear correctly. Resources Optiboot Bootloader (GitHub)
