Adds Paul-contributed TYWE1S carrier-board connection/flashing instructions and the supplied pinout for the Eurom Mon Soleil DSP project. The README now credits Paul (@ph-wheels) for development alongside Graham, with Paul co-authored on the documentation commit.
Corrects typos and clarifies crossed 3.3 V TTL UART connections, the carrier board's separate 5 V input, manual bootloader entry, browser serial installation and reconnection. Board pin numbers and image labels are preserved; the heater-control YAML is unchanged.
The original text did not include backup commands. The edited guide adds an explicitly labelled full-flash backup/readback comparison procedure based on Espressif's esptool documentation. Backup hardware tests, restoration, exact PCB-revision measurements and connector-to-GPIO tracing remain TODO. The guide makes no new model-compatibility or safety-verification claim.
Validation: checked the original connection mapping against the supplied drawing, all local Markdown links, the unchanged PNG bytes, the unchanged heater YAML, esptool 5.4.0 command help and Git whitespace checks. No device was connected, backed up or flashed, and no restoration test or new firmware compilation was performed for this documentation change.
The manufacturer manual, private PUBLISHING.md, firmware dumps and credentials are excluded. Edited/integrated with ChatGPT & Codex assistance; the original hardware notes and pinout are credited to Paul.
