Packed into a tiny 1.4\" × 0.7\" form factor, it delivers 512 KB Flash, 192 KB RAM, and 2 MB of SPI Flash for CircuitPython code and file storage.\n\nShips with CircuitPython pre-loaded — plug it in, edit the Python code on the drive that appears, and your project runs immediately. Also fully compatible with the Arduino IDE. The UF2 bootloader makes flashing as simple as dragging a file to a USB drive.\n\nKey Features\n\n\nATSAMD51 Cortex M4 – 120 MHz, 32-bit with hardware floating point and DSP\n\n512 KB Flash, 192 KB RAM – Plenty of room for complex projects\n\n2 MB SPI Flash – Onboard storage for CircuitPython code, data logging, and files\n\nCircuitPython & Arduino – Ships with CircuitPython; also programmable via Arduino IDE\n\nNative USB – Serial console, HID keyboard/mouse, MIDI, or disk drive\n\n23 GPIO Pins – 7× analogue inputs (12-bit), 2× 12-bit DAC outputs (1 MSPS), 18× PWM\n\nDual 12-bit DAC – Play 12-bit stereo audio clips from A0 and A1\n\nVHigh Output & Level-Shifted Pin 5 – 5V logic output for NeoPixels, servos, and LEDs\n\nDMA NeoPixel Support – Drive 60,000+ pixels without processor overhead\n\nBuilt-in Crypto – AES-256, true RNG, and public key controller\n\nUF2 Bootloader – Drag-and-drop firmware flashing via USB\n\nBuilt-in RGB DotStar LED – Plus red Pin 13 LED\n\n\nIdeal For\n\nHigh-performance CircuitPython and Arduino projects in a compact form\nAudio projects with dual 12-bit DAC outputs\nLarge NeoPixel/DotStar LED installations with DMA support\nShrinking Metro M4 or Feather M4 prototypes into final builds\n\n\nPackage Contents\n\n1× Adafruit ItsyBitsy M4 Express (with CircuitPython pre-loaded)\n1× Header Strip (unsoldered)\n\n\nResources\n\nAdafruit ItsyBitsy M4 Express Guide\nCircuitPython.org\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":6153,"title":"Default Title","sku":"AF-3800","price":30.29,"on_sale":false,"in_stock":true,"available_quantity":4,"option1":"Default Title"}]}
