{"title":"Adafruit Feather RP2040 with USB Type A Host","handle":"adafruit-feather-rp2040-with-usb-type-a-host","url":"/products/adafruit-feather-rp2040-with-usb-type-a-host","description":"The Feather RP2040 with USB Type A Host adds a full USB Type A port to the Feather, letting you connect USB devices like keyboards, mice, flash drives, and serial peripherals. The USB host functionality is achieved through the RP2040's PIO peripheral, which emulates a USB host controller while keeping the USB Type C port available for programming and debugging.\n\nA built-in 1 A boost converter (TPS61023) provides clean 5V power to connected USB devices, even when running from a LiPo battery. The boost converter's enable pin is connected to a GPIO so you can power-cycle connected devices for hard resets.\n\nKey Features\n\n\nRP2040 Processor – Dual ARM Cortex M0+ cores at ~133 MHz, 3.3V logic\n\n264 KB SRAM + 8 MB SPI Flash – For code and file storage\n\nUSB Type A Host Port – Connect USB keyboards, mice, flash drives, and serial devices (D+ on GPIO 16, D- on GPIO 17)\n\nPIO-Based USB Host – Uses second core and both PIO peripherals for USB host emulation\n\n1 A 5V Boost Converter – TPS61023 provides clean 5V USB power with 500 mA resettable fuse; enable on GPIO 18\n\nUSB Type C – Main port for programming, debugging, and data (always available alongside host port)\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\nLiPo Battery Support – JST connector with built-in 200 mA+ charger\n\nBootloader + Reset Buttons – Both BOOTSEL and reset buttons on-board\n\nCompact Design – 50.8 mm × 22.8 mm × 7 mm, weighing 6.3 g\n\n\n\nNote: USB Host support is currently Arduino only (via TinyUSB dual-role examples). The second ARM core and both PIO peripherals are dedicated to USB host handling.\n\n\nAlso Available\n\n\nFeather RP2040 – Base model\n\nFeather RP2040 DVI – With HDMI-compatible DVI output\n\nFeather RP2040 SCORPIO – 8-channel NeoPixel driver\n\nFeather RP2040 Adalogger – With MicroSD card slot\n\nFeather RP2040 RFM69 868/915 MHz – Packet radio\n\nFeather RP2040 RFM95 LoRa 915 MHz – Long-range LoRa radio\n\n\nIdeal For\n\nUSB HID remapping and input device projects\nData logging to USB flash drives\nInterfacing with USB serial devices\nUSB device testing and development\n\n\nPackage Contents\n\n1× Feather RP2040 with USB Type A Host\n1× Header pin set\n\n\n\nNote: LiPo battery and USB cable sold separately.\n","vendor":"Adafruit","product_type":"physical","in_stock":false,"options":[],"variants":[{"id":1656,"title":"Default Title","sku":"AF-5723","price":35.25,"compare_at_price":0.0,"on_sale":false,"in_stock":false,"available_quantity":0,"option1":"Default Title"}]}
