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
