The firmware is generic Arduino. The only problem that I have encountered is the bootloader. The the size of the application plus bootloader must be less than 32K. I don't recall the exact sizes but the newer current firmware (version 1.1) can exceed the free space available with the older bootloaders. The newer bootloader is significantly smaller.
Rewriting the bootloader can be a pain. Requires another piece of hardware. Some of the cheaper Nano "clones" still come with the old while "genuine" have the new.
You can tell the difference by connecting to the device with the Arduino IDE.
There are multiple methods for updating the firmware. T2 from Zax has an advantage in that he supplies the whole package. Firmware plus burn procedure.
Do you have any local hobby clubs such as Makerspace, Mens Shed, or Robotics?
