- Worth noticing
- The planner covers 49 ordering codes across eight S3 and C6 parts and runs in the browser with no data uploaded.
Field notes
The planner flags conflicts as assignments are made and gives examples such as a pin occupied by PSRAM or a strapping-pin warning. Its listed coverage includes S3-MINI-1, WROOM variants, C6 modules, and bare QFN chips; the page says generated settings were tested against ESP-IDF v6.0.2 with warnings treated as errors. Debugger measurements compare OpenOCD and probe-rs on Windows, but Coil’s stated speed figures are targets, not released-product results.
