{"title":"Adafruit ItsyBitsy RP2040","handle":"adafruit-itsybitsy-rp2040","url":"/products/adafruit-itsybitsy-rp2040","description":"The Adafruit ItsyBitsy RP2040 brings the Raspberry Pi RP2040 to the compact ItsyBitsy form factor. Featuring a dual-core Cortex M0+ running at 125 MHz, 264 KB RAM, and 8 MB of SPI Flash, it packs serious power into a board just 1.4\" × 0.7\" — perfect for shrinking prototypes into tiny final builds.\n\nThe RP2040's unique PIO (Programmable I/O) state machines enable custom hardware-level protocols for NeoPixels, I2S audio, LED matrices, and more — all without using the CPU. Supports CircuitPython, MicroPython, and C/C++ with the Pico SDK.\n\nKey Features\n\n\nRP2040 Dual-Core Cortex M0+ – 125 MHz, 32-bit with 264 KB RAM\n\n8 MB SPI Flash – Generous storage for CircuitPython/MicroPython code and data files\n\n23 GPIO Pins – 4× 12-bit ADC, 16× PWM, 2× I2C, 2× SPI, 2× UART\n\nPIO State Machines – 2× PIO peripherals with 4 state machines each for custom hardware protocols\n\nCircuitPython, MicroPython & C/C++ – Multiple programming environment support\n\nNative USB – Built-in ROM UF2 bootloader; serial console, HID, and disk drive support\n\nVHigh Output & Level-Shifted Pin 5 – 5V logic output for NeoPixels, servos, and LEDs\n\nRGB NeoPixel – Onboard addressable LED with power control for low-power modes\n\nReset & Bootloader Buttons – Quick restarts without unplugging\n\n3.3V Regulator – 500 mA output with automatic USB/battery switching\n\nSWD Debug Pins – Broken out for hardware debugging\n\n\nIdeal For\n\nCompact CircuitPython and MicroPython projects\nPIO-driven NeoPixels, I2S audio, and custom protocols\nShrinking Raspberry Pi Pico or Feather RP2040 prototypes\nUSB HID devices, data loggers, and IoT builds\n\n\nPackage Contents\n\n1× Adafruit ItsyBitsy RP2040\n1× Header Strip (unsoldered)\n\n\nResources\n\nAdafruit ItsyBitsy RP2040 Guide\nCircuitPython for ItsyBitsy RP2040\nRaspberry Pi Pico SDK (GitHub)\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":2978,"title":"Default Title","sku":"AF-4888","price":20.18,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":104,"option1":"Default Title"}]}
