The Adafruit ItsyBitsy RP2040 is a compact and powerful microcontroller board featuring the Raspberry Pi RP2040 chip. Small yet mighty, this development board runs a dual-core Cortex M0+ processor at 125 MHz, providing robust performance in a tiny form factor measuring just 1.4" x 0.7" x 0.2". Perfect for projects requiring high speed and numerous GPIO pins in a minimal footprint.Key features include 264 KB of SRAM and 8 MB of SPI Flash memory for code and file storage, along with an extensive set of 23 GPIO pins supporting analog inputs, PWM outputs, I2C, SPI, and UART peripherals. The board also includes an on-board red LED, an RGB NeoPixel powerable via GPIO, reset and bootloader buttons for easy programming, and native USB support through a micro USB connector.The RP2040 chip’s programmable IO (PIO) allows for advanced custom peripheral support such as NeoPixels, I2S audio, and display drivers, extending the board's versatility. Ideal for CircuitPython, MicroPython, and C/C++ development environments, the ItsyBitsy RP2040 makes a great choice for hobbyists and professionals alike. Ultra-compact size: 1.4" x 0.7" x 0.2" (36mm x 18mm x 4mm) without headers Dual ARM Cortex M0+ cores @ 133 MHz 264 KB SRAM and 8 MB external SPI Flash memory 23 GPIO pins with 4 ADC inputs, 16 PWM outputs, 2 UART, 2 SPI, and 2 I2C peripherals On-board red LED and RGB NeoPixel with power control USB Micro B connector for power and programming with built-in UF2 bootloader Reset and Bootloader buttons for easy code uploads 3.3V regulator with 500mA peak output Special Vhigh pin for 5V logic level output and NeoPixel power Compatible with CircuitPython, MicroPython, and C/C++ SDK This board comes with loose 0.1" headers for soldering and breadboard usage. It is perfect for shrinking projects after prototyping on larger boards like the Feather RP2040 or Raspberry Pi Pico.
