Cons
Only one board has a max3232, specified for 3v to 5v operation. All of the max3232 chips overheated (untouchable without getting burned) were not factory programmed.
Highlights
Quality
These allow connections to rs232 lines and convert to ttl level signals, all units work as advertised
I've purchased and used a number of hiletgo products and have enjoyed the product quality and consistency, these modules included.
3v out, which did not make it hot, but resulted in an unreliable transmission and was useless for a serial terminal.

Price
I would not be able to purchase the parts to make this myself for the price!
