Since the module is in QFN package, without any exposed leads the only sensible way was to populate the boards using solder stencil and reflow owen.
Therefore when I ordered PCBs from PCBway I also purchased framed stencil which consisted of all the boards I have ordered.
The sensor sticks worked in the first iteration. But ESP replacement modules require a small connection to be made to rf_vdd.
For programming a footprint for tag connect is used.
