  • It is recommended that two components for the Mellow FLYF407ZG Board have heat sinks installed. The board I received from Mellow did not have heat sinks supplied inside the package, but you can buy some from Amazon here

  • Some boards shipped are missing the bootloader. If your board has the Mellow logo on the back and when you place a firmware.bin file on the SD card and it doesn’t get converted, then yours is one of these boards.
