What you need
An Original JOXU Edge (ESP32-C3 SuperMini, already flashed). USB-C only for power — a phone charger is enough. Your JOXU password. Phone or laptop to join the board Wi-Fi. No Chrome flash, no computer cable.
Original JOXU Edge: the firmware is already on the SuperMini. USB-C is power, not a flash cable.Devices → Add remote (or Manage device on an existing Edge card).
