If there are some limitations in nnCron LITE: maximum crontab size, maximum crontab line length, maximum tasks count?
There is only one known limitation: the maximum length of a line in a crontab should not exceed 512 symbols. Every nnCron LITE task is silently compiled into independent Forth-word and is stored in a common Forth-dictionary, which allocates 512 KB of memory. The words from nnCron LITE core are stored in the same memory area as well. Thus, there are around 300-350 KB of free memory available for storing the compiled tasks: enough to store more than 1000 tasks – quite reasonable limitation.
