Adafruit ItsyBitsy 32u4 - 3V 8MHz

What's smaller than a Feather but larger than a Trinket? Meet the Itsy Bitsy, a compact, powerful microcontroller board that is Arduino-compatible. Perfect for those seeking a tiny yet feature-packed solution, Itsy Bitsy measures only 1.4" by 0.7", offering 6 power pins, 6 analog & digital pins, and 17 digital pins.

Its capabilities align with those of an Arduino UNO or Feather 32u4, making it ideal for transitioning from larger Arduino prototypes to more compact projects. Powered by the Atmega32u4 chip, it matches the voltage and speed of the Feather 32u4, ensuring seamless compatibility with many existing projects. Program it effortlessly using the Arduino IDE.

This board enhances the Pro Trinket 3V by providing native USB support, improving computer compatibility, USB serial debugging, and offering a reliable bootloader. The Itsy Bitsy can even pair with the Pro Trinket LiPo backpack for rechargeable battery capabilities.

Additional features include a VHigh power pin, delivering the higher voltage of VBAT or VUSB, and a specially connected digital #5 pin that serves as a high logic output. This is ideal for driving NeoPixels, servos, or high-dropout-voltage LEDs.

Specifications include: a QFN package ATmega32u4 chip, 3.3V power and logic, 8 MHz clock rate, 2KB RAM, 28K FLASH, USB bootloader with LED indicator, Micro-USB jack, HID Keyboard/Mouse/MIDI capabilities, on-board power regulator with multiple protections, and more.

With 23 GPIO, 6 analog inputs, and versatile connectivity options, you can drive NeoPixels, connect sensors, and operate servos efficiently. Its reset button and multiple peripherals make it an all-encompassing solution in a small package. For additional information and project resources, refer to the comprehensive learning guide.
