OK but better documentation is needed for DIY use. Datasheet is too complex .. Transportation took too long.

Sorry about the shipping delay - the US Postal Service is in a bit of a mess at the moment, it's very hit and miss. Usually I'm seeing international shipments delivering in 2 weeks, but there have been a couple where it just sat in a warehouse somewhere for an extra month. Hopefully this will get back to normal later this year.
If you are using these on the Arduino, ignore the ACE datasheet and follow the instructions in the github readme and the comments in the library file and the example sketches. If you are not using these on Arduino and writing support from scratch on another platform, feel free to adapt from the Arduino code.
If stuck, please send me a message through Tindie, I should get a notification and be able to respond quickly.
