I’m building my first keyboard (a dumbpad), and I have a basic question which should be easy to solve when you know how to do it.
I’ve choosen to socket the microcontroller (in case of error, bad choice…) but I have now a question for putting the screen above: what kind of header should I use ? Is there high profile header or should I stack multiples headers ?
I see. So you have two sets of sockets: soldered ones (those on your controller) and hot-swappable ones (those on your board), and you've stacked them. It will probably work fine, but the usual approach is using only one of these.
The dumbpad requires the controller to be facing up. The PCB helps because the pinout is printed on the board, and I’ve double checked the "GND" pins with the square hole on the controller. I’ve already plugged the controller and test the reset button: everything worked fine !
Thanks for your video ! I will see if I can keep some diode legs as male pin the screen.
