What's smaller than a Feather but larger than a Trinket? It's an ItsyBitsy! This compact yet powerful microcontroller board is Arduino-compatible and only 1.4 inches long by 0.7 inches wide, featuring 6 power pins, 6 analog and digital pins, and 17 digital pins, replicating much of the Arduino UNO's capabilities.
The ItsyBitsy 32u4 5V 16MHz utilizes the Atmega32u4 chip, similar to the Arduino Leonardo and Feather 32u4, running at the same speed and voltage as an Arduino UNO. Perfect for shrinking your prototype projects, it allows seamless programming via the Arduino IDE and compatibility with numerous Arduino projects.
Beyond compactness, it offers native USB support for enhanced connectivity and a more reliable bootloader. Pair it with the Pro Trinket LiPo backpack for a rechargeable battery setup. Key specifications include a USB bootloader with a LED indicator, Micro-USB jack, and onboard 5.0V power regulator with 150mA output.
Its versatility enables it to function as a USB HID Keyboard, Mouse, MIDI, or plain USB 'CDC' serial device. The ItsyBitsy comes equipped with features like 23 GPIO total, PWM support, a reset button, and can drive NeoPixels, connect to sensors, and servos.
