   M-VAVE FM-1

   Firmware target.

   Check the selected seller variant and flash revision. New UC25HQ80 units are not equivalent to a tested older unit. Music Arms lists the actual FM-1; shipping outside Thailand and flash revision must be confirmed. A seller page does not verify third-party firmware compatibility.

   Required

   USB-C data cable

   Connect to the computer for programming or data.

   A charge-only cable cannot flash firmware. Example requires a USB-A host port. If your computer has only USB-C, use an appropriate USB-C data cable instead. Reuse the device’s included cable where possible; this is not a standalone power-supply recommendation.
