Worked fine. But the solders of the relays on the botton layer was not very good. I re-solder them. The manual of the commands is super simple but enough to uderstand the commands. The module has two digital inputs that read correctly with 5V logic level. Nice module. Appart from the solders at the botton, it is very well made. The board has a MAX485 and a STM8S003F3 microcontroller.
