GHOST TAP UART — partial schematic built
I renamed the project and created an actual 33-component, 26-net circuit, not just a block diagram. It includes:
- A U1 configured electrically for local 3.3V logic.
- USB-C with separate CC resistors, USB ESD protection, and decoupling.
- Cross-coupled DTR/RTS auto-program circuitry, manual BOOT/RESET buttons, and an optional disconnectable EN timing capacitor.
- A J2 for TX, RX, GND, BOOT, and EN—no target power connection.
- POWER/TX/RX LED circuits and voltage-monitor test points. TX/RX indicators still require verified bridge configuration instructions.
The auto-reset DC simulation matched all four DTR/RTS states. This verifies static logic, not successful flashing or reset timing on your Levoit.
Not finished
- ERC still reports two undriven USB VBUS pin errors; USB host power explains them, but their formal disposition remains unresolved.
- PCB layout has 68 reported airwires. Intentional placement, routing, silkscreen, final DRC, and manufacturing exports are not complete.
- Readable schematic cleanup was blocked by unavailable symbol-arrangement capabilities; Contact Support for that platform limitation.
- Final connector footprint audit, LED provisioning, power/inrush checks, and independent review results have not been reconciled. Do not order this PCB yet.
The requirements are saved in the project files: Project Specification. The next steps are to finish schematic verification and cleanup, approve the board plan, then place, route, and validate the PCB.
Safety: this adapter is not isolated. Do not connect it to a mains-referenced appliance controller; verify an isolated low-voltage target supply and the actual Levoit signal points first.
Execution stopped because your ACUs ran out.
