Soldered all the parts!

I managed to solder for the first time in my life.
All SS49E sensors are bent so that the sensor side is up
I made sure not to reverse the capacitors since they were electrolytic. (they pop and is kind of dangerous, for anyone who didn’t know)

CAD for Mouse and prototype.

1. CAD for Mouse

• Simple casing for the magnet to go in
• Compliant mechanism to work as a click

1. Prototype

• Prototyped on breadboard
• Successfully connected 3 SS49E sensors to each of the analog input in the pico

I finished the PCB and case design. I kept the case simple since it is just supposed to function as a mouse pad.

I had to fix the footprint for the hall effect sensor (SS49E) because it was designed to have the pads too close to each other for manufacturing.

In the process I had to reroute the copper to accommodate the new footprint.

I worked on the PCB design after fixing the symbol for the hall effect sensor.
