We are re-engineering the old PCB board into a modern PCB for a simple swap. The goal is to get an up to date RPI computer

Preparing to add a very low power switch...
I had to revert KICAD back from nightly build to stable and lost a pqart of the work because of file down compatibility issues. I had to redo the routing.
Here is the first experimental schematic diagram (still some work to do). Until I get a Compute module 3, I will use the RPI PI ZERO W computer.
Next step tomorow
I also got the Voyage 200 model which replaced the TI92. All the work made with TI92 will speed up the conversion process for the new model
Now trying to connect the 4 inch to the RPI PI ZERO . Looks like this tutorial will ease the process . Shows how to install ST7796s on raspbian. The website also offers pre-compiled images.
I tried to route a bit... everything seems ok. There is much room to work with security and comfort.
Before I finish the routing I have to finish the schematic with the RPI stuff.
Time to read on how to drive the display with the RPI ZERO and RPI CM4 .
oups, thanks to you for the comment
There was a mistake in the buttons footprints
I corrected the button mistake ... and updated the files
I've just updated the GITHUB directory with the latest kicad dev (please is the last nighly built of kicad to open the files)
I added the buttons on the board.
It is not time to work on the raspberry pi zero and RPI Compute module 4 add.
I've updated the github file Kbpad.kicad_mod which is a pcb gamepad footprint. Fortunately I've made them in the past for another project. They can be reused with no problem.
