Software & Firmware

The OnSpeed firmware runs on the ESP32-S3 microcontroller. Pre-built firmware for both hardware variants (V4P and V4B) is available from GitHub releases (stable) or as a latest-master CI build (development; no GitHub login required). For routine updates when your OnSpeed is already running, use OTA over WiFi. For initial setup or recovery, use USB flashing.

• Flashing Firmware — Download and flash pre-built firmware via USB
• OTA Updates via WiFi — Update firmware wirelessly through the web interface
• Building from Source — For developers: compile the firmware yourself
• Audio Tone Spec (WIP) — Developer reference for the aural-tone subsystem; aspirational, not yet matched by current firmware
