• Hi - sorry for the delay, just saw this.

    In terms of RAM it's blocksize*free - so 3360 bytes. The reality is it's slightly less than that due to various overheads.

    However there is 2k of flash available, and if you save code to flash it'll be executed from there and won't use RAM, so I'd suggest doing that - so you get 2k of code space plus 3k of RAM.
