Arduino Circuit Design


Make an arduino uno with two 16 channel microcontrollers connected and 100 kOhm resistors
Your goal is a new controller board with two 16-channel devices and 100 kOhm resistors built around an Arduino-style main controller.
  • I’ve created a plan to:
    1. Start a new editable design project
    2. Add the main controller, the two 16-channel devices, and the resistors
    3. Wire everything together
    4. Review it so it’s ready for layout

Check this schematic component against the datasheet for [MPN] and assign the correct pin orientation, section, and terminal order without changing, replacing, renumbering, or remapping any pins. Remove the Pin Group property from all pins if it exists. Place Power pins first and Ground pins last. Within each section, distribute the pins as evenly as possible between the left and right sides; for example, split 10 pins as 5/5 and 11 pins as 5/6 or 6/5. If a section contains only one pin, leave it on the most appropriate side. Keep the symbol compact, balanced, and visually symmetrical. If a pin function is unclear, assign Unclear / Check datasheet, then apply all changes directly to the schematic component.
Please provide the actual MPN and the schematic component designator (for example, U1). The [MPN] placeholder doesn’t identify a datasheet, so I can’t safely assign pin orientation, sections, and terminal order without risking an incorrect symbol.
