A software-only USB device stack for the ESP8266/ESP8285, implementing low-speed (1.5 Mbit/s) USB in firmware with just one external resistor. It includes examples such as a simulated USB keyboard/mouse controllable via a web interface.

Use cases

  • add USB device capability to an ESP8266 without USB hardware
  • build a DIY USB keyboard or mouse
  • send control messages from a host to an ESP8266 over USB
  • create custom low-speed USB peripherals
  • experiment with bit-banged USB protocols

When to choose

  • you need USB device functionality on an ESP8266/ESP8285 with minimal hardware
  • you're building simple HID-style peripherals at low-speed USB
  • you want to learn how USB works at the protocol level

When to avoid

  • you need high-speed or full-speed USB throughput
  • you need USB serial bridges or network devices
  • you rely on ESP SDK 2.0 or newer SDKs
  • you're using a chip other than the ESP8266/ESP8285
