Key Features​

  • Microcontroller: ESP32-S3 for reliable and fast processing.
  • USB Host Capabilities: Automatically translates standard USB HID devices (Keyboards, Mice, MIDI) into easily parsable data.
  • Multi-Protocol Output: Selectable communication interfaces including I2C (default), UART, and SPI.
  • Software Support: Fully supported by a dedicated open-source Arduino library with built-in event structures.
  • Advanced Data Modes: Access raw HID reports and USB descriptors, or use ready-made parsed events.
  • Efficiency: Supports standard polling or an interrupt-driven mode (via the INT pin) to save host MCU CPU cycles.
  • USB Interface: Female USB-A connector with overcurrent protection (Max 260mA).
  • Power Supply: 3.3V logic, equipped with an onboard 3.3V to 5V boost converter.
  • Qwiic (formerly easyC) Ecosystem: Qwiic connectors (SMD) for fast I2C device integration.
