## Description

The Adafruit Itsy Bitsy 32u4 5V packs the power of an Arduino Leonardo into a tiny 1.4" × 0.7" board. Built on the ATmega32u4 running at 5V and 16 MHz — the same speed and voltage as an Arduino Uno — it's perfect for shrinking finished prototypes into compact final builds. With native USB, the Itsy Bitsy 32u4 can act as a USB keyboard, mouse, MIDI device, or serial port. Programmed via the Arduino IDE using the same USB bootloader as the Feather 32u4 and Leonardo, most Arduino projects work out of the box. Key Features ATmega32u4 Microcontroller – 5V logic, 16 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 Onboard 5V Regulator – 150 mA output, up to 16V input, with reverse-polarity and thermal protection 3.3V Regulator Output – Low-current 3.3V from the chip for small sensors Automatic Power Switching – Runs from USB or battery (VBAT pin) with seamless switchover Arduino Uno Compatible – Same voltage and speed; vast Arduino project library works directly Compact Form Factor – Just 1.4" × 0.7" (35.6 × 17.8 mm) Ideal For Shrinking Arduino Uno/Leonardo prototypes into compact builds USB HID devices — custom keyboards, mice, and MIDI controllers Wearable electronics and space-constrained projects Battery-powered builds with automatic USB/battery switching Package Contents 1× Adafruit Itsy Bitsy 32u4 5V 16 MHz Note: Headers are not soldered on. You'll need to solder headers for breadboard use. Resources Adafruit Itsy Bitsy 32u4 Guide
