Finished PCB

I was able to finish the pcb.

After finding out that my components would need to be advanced pcba, I just decided to use 0201 smd components because they fit better.

Routed the PCB

I routed the PCB today.

After putting into JPCPCB, they cannot put on the barometer, and because it is not as important, I will just remove it. I also need to replace all the 0402 caps with 0201 ones.

Finished PCB Schematic

I finished the schematic for the PCB.

Most of it was copied from datasheets & online tutorials, and I am hoping it works. The pin layout is just going to be the same as the rpi Pico, but hopefully my extra sensors will fit too.

Chose Components

I will be using an rp2040, because I have experience with this microcontroller.

For the gyro and barometer, I chose the MPU5060 and mpl3115a2, because I have used both of these, and because the gyro has a gyroscope and accelerometer.

For the battery charger, I want to use a MCP73871, because it can charge the battery while powering the system at the same time.
