TinyUSB is an open-source, cross-platform USB Host and Device stack for embedded systems written in C. It is designed for memory safety (no dynamic allocation), thread safety, and portability across 50+ MCU families, supporting classes like CDC, HID, MSC, Audio, and WebUSB.

Use cases

• implement USB device firmware on a microcontroller
• add USB host support to an embedded project
• create a USB HID keyboard or mouse device
• expose USB CDC serial port on an MCU
• implement USB mass storage (MSC) on embedded hardware
• add WebUSB support to a firmware project
• use USB MIDI on a microcontroller

When to choose

• you need a portable, well-supported USB stack across many MCU families
• you want a memory-safe stack with no dynamic allocation for embedded use
• you need both USB host and device support in one stack
• you use an RTOS like FreeRTOS, RT-Thread, or Mynewt, or run bare metal

When to avoid

• you need USB support only on desktop/server operating systems
• your target MCU is not among the supported 50+ families and you cannot write a port driver
• you need a high-level USB API rather than a low-level embedded stack
