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.

A 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.

Key Features

  • RP2040 Processor – Dual ARM Cortex M0+ cores at ~133 MHz, 3.3V logic
  • 264 KB SRAM + 8 MB SPI Flash – For code and file storage
  • USB Type A Host Port – Connect USB keyboards, mice, flash drives, and serial devices (D+ on GPIO 16, D- on GPIO 17)
  • PIO-Based USB Host – Uses second core and both PIO peripherals for USB host emulation
  • 1 A 5V Boost Converter – TPS61023 provides clean 5V USB power with 500 mA resettable fuse; enable on GPIO 18
  • USB Type C – Main port for programming, debugging, and data (always available alongside host port)
  • STEMMA QT / Qwiic – On-board I2C connector for solderless sensor connections
  • NeoPixel – On-board RGB LED for status feedback
  • 21 GPIO Pins – 4× 12-bit ADC, 16× PWM, 2× I2C, 2× SPI, 2× UART
  • LiPo Battery Support – JST connector with built-in 200 mA+ charger
  • Bootloader + Reset Buttons – Both BOOTSEL and reset buttons on-board
  • Compact Design – 50.8 mm × 22.8 mm × 7 mm, weighing 6.3 g
Note: 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.
