YesMan Schematic Design Discussion

Thought for 45 sec

Core parts are available in the library, including the exact ESP32-S3-WROOM-1-N8R2, MCP73871, TPS63031, ICS-43434, USB-C receptacle, USB ESD device, and SP3T slide switch. I’m adding the schematic blocks now with conservative first-draft support passives and verification notes.

Worked for 9 mins 34 sec

flux

Created the YesMan schematic draft in the project and renamed the project to YesMan. I added the ESP32-S3-WROOM-1-N8R2, USB-C/native USB path, LiPo charger/power-path, buck-boost supply, display FPC, ICS-43434 microphone, buttons/mode switch, independent buzzer/motor drivers, connectors, test pads, named nets, and review documentation.

Open items:

This is a first engineering draft, not production-ready.
MCP73871 configuration pins and TPS63031 component values/topology still need datasheet-level human verification.
Display FPC orientation and backlight driver topology must be verified against the actual WH-N133-2424THBIG26-A8 cable/module.
PCB layout was not started.

Suggested next steps:

Review the detailed file: yesman-schematic-draft-review.
Review firmware/compliance notes: yesman-firmware-and-compliance-notes.
Ask me to do a second-pass datasheet cleanup for MCP73871/TPS63031/display backlight.
After schematic sign-off, ask me to start PCB placement with antenna, microphone, USB, and regulator constraints.
