You should order with ENIG (electroless nickel immersion gold) plating. While the cartridge will work with HASL you will getter contact with ENIG and it is less prone to wearing down.

Questions
How big is the Grove level shifter PCB?
It measures 21.6 × 45.7 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Grove level shifter use?
14 parts, built around the TXB0108PW. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Grove level shifter KiCad files?
From the jimmo/microbit-boards repository on GitHub, at the commit this page was made from: the board is grove-level-shifter/grove-level-shifter.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Grove level shifter design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
