Product arrived in an envelope, with poor protection. Hopefully it seems to be working. I installed it on a nano board. I could not find a way to flash it. All methods described on MKS documentation did not work for me. I see the board wireless available to connect to it. The only way I could connect was using Cura. Anyway, if I send something ti the printer, the upload get stuck between 1% and 3%. Considering all the trouble, it is better to use Octopi and stay away from this module.
The device is working and I have connected to Wi-Fi on the phone. But I haven't understood out how to connect the printer to CURA yet.
