Looking for someone interested in helping design a Raspberry Pi Pico 2 calculator PCB

I'm building a custom graphing calculator as a hobby project and I'm looking for someone interested in helping with the schematic design.

The calculator is based around a Raspberry Pi Pico 2. My original goal was to design a completely custom motherboard using the RP2350A directly, but after spending a lot of time in KiCad I've realized that's probably beyond my current skill level. I'm now open to either:

• A custom PCB that uses a Pico 2 module
• A full RP2350A design if someone thinks it's realistic

Current goals:

• Fit inside a calculator-style enclosure
• 2.8" SPI LCD display (ILI9341 based)
• USB-C charging and data
• LiPo battery
• Calculator keypad matrix (around 50 keys)
• SWD programming header
• Single custom PCB instead of lots of loose wiring

I already have:

• Raspberry Pi Pico 2
• LCD display
• Battery
• KiCad project files
• A rough idea of the internal layout

I attempted the schematic myself but quickly got overwhelmed by the RP2350A power section, KiCad ERC errors, keypad matrix design, and the overall PCB design process.

I'm not expecting anyone to do a huge amount of work for free, but if you're interested in helping, reviewing the design, collaborating, or pointing me in the right direction I'd really appreciate it.

Thanks!
