    Here you can find pins for flashing with UART ---> https://developer.tuya.com/en/docs/iot/wblc9-module-datasheet?id=K9hgglry2jp5h
    Diagram of boards with pin labels for flashing.
    Here is UART flasher: https://github.com/openshwprojects/BK7231GUIFlashTool

    But you can flash via Wi-Fi because there is a profile, so no soldering is required.
