*Total units that you will need to order from that specific AliExpress listing. It's not how many components you will need, it's how many to order!
For example the AliExpress 1N4148 diode listing has a minimum quantity of 100, so the total units required for the keyboard is 1 and not 64.
**Ordering keycaps is a bit different, you need to buy the amount you want and then send the seller a message with desired colors, sizes and amounts.
For reference, this is how my message looked like:
32 * 1u DSA11 Deep Purple
22 * 1u DSA12 Wathet
16 * 1u DSA3 Yellow
2 * 1.25u DSA11 Deep Purple
2 * 1.5u DSA11 Deep Purple
2 * 1.25u DSA16 Pink Mauve
2 * 1.5u DSA16 Pink Mauve
Total: 86
***I already had below items at home or a colleague gave them to me. I made a suggestion what I would order if I didn't have those items but keep in mind that I didn't verify them.
****Any wire with 3 cores should be fine. This is just a random suggestion, explore a bit more and find the cable that fits you and your keyboard style. You can also buy Braided Cable Sleeves to make your cable even fancier.
*****This cable says that it has 4 wires (cores) but I didn't verify it. If you order it and the keyboard doesn't work but the Pro Micro is on, try any other USB Type C cable that has data transfer capabilities.
