My first pcb
Hello, I'm new to PCB design and I was wondering if someone could help me with a project. I want to design my own PCB based on a Casio FX-95MS calculator. My idea is to place the membrane keyboard on one side of the PCB and an ESP32, a LiPo battery, and a TP4056 charging module on the other side.
My main problem is that I don't know how to replicate or trace the original keyboard connections and transfer them into KiCad. Could someone explain the process or point me in the right direction?
Any advice would be greatly appreciated. Thank you!
