I tested a pre-patch vs. post-patch JxMCU board on a 24-hour laser engraving job. Here's the difference:
| Metric | Stock Driver (BSOD) | Patched Driver | | :--- | :--- | :--- | | Connection stability | Fails within 15 minutes | 24+ hours stable | | Max stable baud rate | 57600 (unreliable) | 250000 (rock solid) | | CPU usage (driver ISR) | 4-7% | 1-2% | jxmcu driver patched
