## Description

The Adafruit Itsy Bitsy 32u4 3V packs the power of an Arduino Leonardo into a tiny 1.4" × 0.7" board. Built on the ATmega32u4 with native USB, it's perfect for compact projects that need a full set of GPIO pins without the bulk of a standard Arduino. Running at 3.3V and 8 MHz, the Itsy Bitsy 32u4 is programmed via the Arduino IDE using the same USB bootloader as the Feather 32u4 and Arduino Leonardo. It can act as a USB keyboard, mouse, MIDI device, or serial port — no FTDI adapter needed. Key Features ATmega32u4 Microcontroller – 3.3V logic, 8 MHz clock, 2 KB RAM, 28 KB Flash Native USB – USB HID keyboard, mouse, MIDI, or CDC serial; Micro-USB connector 23 GPIO Pins – 6 analogue inputs, SPI, I2C, hardware serial, 4× PWM, and more VHigh Output Pin – Outputs the higher of VBAT or VUSB for powering external devices Level-Shifted Pin 5 – 5V logic-level output for driving NeoPixels, servos, or LEDs from a 3.3V board Onboard 3.3V Regulator – 500 mA output, up to 6V input, with reverse-polarity and thermal protection Automatic Power Switching – Runs from USB or battery (VBAT pin) with seamless switchover Compact Form Factor – Just 1.4" × 0.7" (35.6 × 17.8 mm) Ideal For Compact Arduino projects after prototyping on a full-size board USB HID devices — custom keyboards, mice, and MIDI controllers Wearable electronics and space-constrained builds Battery-powered projects with automatic USB/battery switching Package Contents 1× Adafruit Itsy Bitsy 32u4 3V 8 MHz Note: Headers are not soldered on. You'll need to solder headers for breadboard use. Resources Adafruit Itsy Bitsy 32u4 Guide
