Adafruit ItsyBitsy 32u4 - 5V 16MHz

The ItsyBitsy is a tiny yet powerful microcontroller board that offers compactness and functionality. Measuring just 1.4" by 0.7", it provides 6 power pins, 6 analog & digital pins, and 17 digital pins, similar to an Arduino UNO. It’s perfect for shrinking down your project once you've prototyped it on a larger board.

Powered by the Atmega32u4 chip, the ItsyBitsy runs at 5V with a 16MHz clock speed, offering the same capabilities as the Arduino Leonardo. It's fully compatible with the Arduino IDE, so you can easily program it with a vast range of Arduino projects.

With native USB support, it can work seamlessly with any computer for programming and debugging. It also includes features like USB HID support (keyboard, mouse, MIDI, or serial device), a micro-USB port, and a reliable bootloader. It's an ideal upgrade from the Pro Trinket, especially with added features like rechargeable battery support when used with the Pro Trinket LiPo backpack.

Key specifications include:

• ATmega32u4 chip (5V, 16MHz)
• 2KB RAM, 28KB FLASH
• USB bootloader with LED indicator
• On-board 5V power regulator (150mA) and 3.3V regulator for small sensors
• 23 GPIO pins (6 analog, 10 digital, 4 with PWM)
• Micro-USB for power and USB uploading/debugging
• Reset button for bootloader entry or restarting the program
• Dimensions: 35mm x 18mm x 4.1mm (1.4" x 0.7" x 0.2")
• Weight: 2.6g (0.1oz)

This small but mighty board is perfect for your compact, Arduino-compatible projects, whether you're working with NeoPixels, sensors, or servos. Plus, with built-in protection features like reverse-polarity and thermal protection, it's a reliable choice for any maker.
