Circuit schematic design (PCB artwork is not inclueded)

Job ID: 32352206

Budget: $30 – $250 USD

Base on Open source hardware project, adding I2C seonsors and SPI modules.
All modules have schematic.sch files(Eagle Cad). Those are for dev modules,
remove un-necessary leds, switches, pin outs and adding I2C , SPI modules

This is initial project, so there will be new projects following up continuously,
such as artwork and modifications.
Feel free to apply, and I look forward to work with you.

<Please see the attached files for requirements>

1.Change main MCU to a sibling mcu that has PSRAM on it.
2.Adding 5ea I2C sensors, 2 SPI modules
3.Adding new Wireless charge module

This project don't have PCB Artwork. Just check the considerations and
redraw the schematic design. Results includes raw schematic design file
(any tools possible, but Eagle Cad is preferred)
