{"title":"Adafruit Feather RP2040","handle":"adafruit-feather-rp2040","url":"/products/adafruit-feather-rp2040","description":"The Feather RP2040 brings the Raspberry Pi RP2040 dual-core processor to the Feather platform. With two ARM Cortex M0+ cores running at ~125 MHz, 264 KB SRAM, 8 MB SPI flash, and the RP2040's unique PIO (Programmable I/O) state machines, this board offers excellent performance for CircuitPython, MicroPython, and C/C++ development.\n\nThe RP2040's PIO system lets you create custom hardware-level peripherals in software — driving NeoPixels, I2S audio, LED matrices, SPI displays, and even VGA output with precise timing and no CPU overhead. The board includes a STEMMA QT connector for quick I2C sensor connections, USB Type C, and the standard Feather pinout for FeatherWing compatibility.\n\nKey Features\n\n\nRP2040 Processor – Dual ARM Cortex M0+ cores at ~125 MHz, 3.3V logic\n\n264 KB SRAM – In six independent banks\n\n8 MB SPI Flash – Shared between program code and file storage (~7 MB available for CircuitPython files)\n\nPIO State Machines – 8 programmable I/O state machines for custom hardware peripherals\n\nUSB Type C – Native USB with UF2 bootloader (hold BOOTSEL during boot to enter)\n\nSTEMMA QT / Qwiic – On-board I2C connector for solderless sensor connections\n\nNeoPixel – On-board RGB LED for status feedback\n\n21 GPIO Pins – 4× 12-bit ADC, 16× PWM, 2× I2C, 2× SPI, 2× UART\n\nPIO-Friendly Layout – 8 consecutive digital GPIO pins for maximum PIO compatibility\n\nLiPo Battery Support – JST connector with built-in 200 mA+ charger and charging status LED\n\nBootloader + Reset Buttons – Both BOOTSEL and reset buttons on-board\n\nOptional SWD Debug – Solder pads for debug access\n\n24 MHz Crystal – For precise timing\n\nCompact Design – 51 mm × 23 mm × 7.5 mm, weighing 5 g\n\n\n\nNote: The RP2040 is a Cortex M0+ chip without hardware floating point or DSP instructions. Floating-point maths is performed in software, which is slower than Cortex M4-based boards like the Feather M4.\n\n\nAlso Available\n\n\nFeather RP2040 Adalogger – With MicroSD card slot\n\nFeather RP2040 SCORPIO – 8-channel NeoPixel driver\n\nFeather RP2040 RFM69 868/915 MHz – Packet radio\n\nFeather RP2040 RFM95 LoRa 915 MHz – Long-range LoRa radio\n\nFeather RP2040 USB Type A Host – With USB host port\n\nFeather RP2040 DVI – With HDMI-compatible DVI output\n\n\nIdeal For\n\nCircuitPython and MicroPython development\nPIO-driven custom peripherals (NeoPixels, displays, audio)\nPortable battery-powered projects\nRapid prototyping with STEMMA QT sensors\n\n\nPackage Contents\n\n1× Feather RP2040\n1× Header pin set\n\n\n\nNote: PCB colour may vary. LiPo battery and USB cable sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":true,"options":[],"variants":[{"id":3426,"title":"Default Title","sku":"AF-4884","price":23.31,"compare_at_price":0.0,"on_sale":false,"in_stock":true,"available_quantity":100,"option1":"Default Title"}]}
