    Chipset: BK7231N

    Two images of a universal remote control box with Powered by Tuya branding, showing the front and technical details on the side.

    Flashing procedure:

    Underneath the PCB are pads for serial TX/RX. Annoyingly the silk screen text is mirrored but not too hard to figure out. Power board using USB-C.

    I had success with an FTDI USB to TTL and BK7231 GUI Flash Tool

    I also have the same device but at the moment with original firmware.
    I need support for IR RAW sending as my device requires long data streams.
    Until I see RAW IR SEND supported on OpenBK, I have put the flashing on hold.
