I want to create a pcb that will act as cover for the following din rail box:

The pcb dimmensions(155.4 x 42) and mount holes will replace the DM9G-COVER and will fit into the D9MG body.

On the pcb top there will be nothing mounted since I will apply a membrane keyboard on top of it. The membrane connectors should be directly soldered to the pcb(i don't know if we can solder them on top).

The pcb will have a cutout of about 33mm x 45mm in order to be able to see the display through it and the 2.2" TFT display will be mounted behind it.

We have to figure a way of mounting the 2.2" display on the pcb bottom with the screen facing towards the top.

The 2.2 display that we will use is this one: [login to view URL]

We will use the Adafruit schematics [login to view URL] from here: [login to view URL]

Instead of the JP1 10 pins connector we will use a fpc smd connector where we will also link the membrane keyboard pins.

The membrane keyboard will have 16 keys that will have 8 pins which i was thinking to link to a CD4021BM96 through 10k resistors in order to use less pins when connecting the PCB to my Arduino controller.
