Delivery 3 weeks. The seller has a separate engineer for those support. Send the documentation forcibly, to the Post Office. Although, I found everything myself in Nete. A lot of information. They sent the documentary anyway. Took 2 pcs. Packed in factory packaging and in package. Manufacturer of these modules! Original office.
Came not quickly, but works. The seller this time "fell asleep" on the shipment. A noticeable difference from other modules-all the conclusions on the faces of the PCB-can be soldered to the main board without a hair dryer.
