For update Tm F16FLCS+TQS is need PCB's for TLE501x and for Shift Register for inside TQS, or use diode matrix there, since is only 10 buttons, or 14, depends on what (HAT, micro-stick...) you use for replace the "eraserhead" TDC, this device is no longer usable.

PCB's available in OS Park.

For TLE501x the PCB layout is a bit "obsolete" (based on this Mega_MOZG sketch, posted above):

The four resistor in inputs is no more needed, but is just matter of make bridges in their places (or use 0 OHM resistor), in this way:

F-16FLCS grip already have a CD4021 Shift Register inside, no need make a new.

PRO Micro shielded PCB is a convenience for simplify, at some degree, connect the wires, but is not necessary. Your choice.
In Debolestis OSPark has PCB for make one.

For what I know for buy in Taobao (a kind of Chinese eBay) you need a "Taobao agent" - that will buy there and resend for you, for a give fee (Google for it). This "kit's" is done by Flight Simmer. In Eagle forum a guy buy from this vendor without problem.

Google Translator handle Chinese characters reasonable well - at least better than German.
