What is where

A square board

The TK23 is 31.0 mm on each side, square, with a mounting hole in each corner. The holes are 4.8 mm across and their centres are 24 mm apart both ways. Almost everything else is the stick.

Under the cap

Pick a part and the figure rings it, with the cap see-through when the part is under it. The stick sits on a 16 mm square frame. A potentiometer on the frame's left side gives X, one along its bottom gives Y, and a push switch on the side away from the header is what the stick presses when you push it straight down.

Up the left edge, from the top: R10, the pull-down on SW, printed PULL-DOWN; R9 and the blue light printed SW; R1 and the red light printed PWR. The PWR light is on whenever the board has power. The SW light is on while the stick is pressed, and dim on a 3.3 V board. Both work without a sketch, which makes them the first thing to look at when a reading seems wrong.

Height

The supplier's drawing puts the bare stick 19.6 mm above the board and the frame 11.9 mm. The cap sits on top of that: in the 3D model its top is about 29 mm above the board and it is about 25 mm across. The header and the small parts are far lower, so the cap is the number that decides a lid or a panel.
