Digi-key part for ordering

In the linked eevblogs post[1], the poster found a digikey partnumber(H122178CT-ND) of a fitting female connector, with a minimum order quantity of 1. Maybe add that to the README, so if you want to build a project using this keyboard, you can buy the right part.

outline

Nice work on curating all this info and creating the parts you have so far. It's providing a great starting point for my project.

Would be great to see what you have with the outline so far, I have a keyboard arriving this week and could help out finishing it up if needed.

"Pressing and holding a letter key inserts capitalizes the letter" Do we know how long?

Great work here. We should capture as much detail as possible, including temporal behaviour such as how long to hold it before it transitions (I might be able to find the results from a BB Passport).

Questions about backlight LED

Hello,

I've been wondering about the backlight LEDs. I dont quite understand the labels on those 4 pins, but I saw some i2c project and saw they just put 3.3V for the upper 2 pins and drive the bottom 2 to GND via mosfet.

Now the questions that I have:

1. Are there any resistors inside the keyboard module? So we can calculate the current and add another resistor for 5V
2. How much current do they drive? Is the transistor really necessary? If it's only few mA I would just sink it to GPIO.
