​​FAQ​​

1.
​​Q: Burn failure (for Arduino IDE "Timed out")?​​

A: ① Check CH340 driver (COM port exists); ② Redo burn mode activation (hold BOOT >500ms); ③ Reduce baud rate to 115200bps.

2.
​​Q: Camera init failed (error 0x105/0x201)?​​

A: ① Short CAM_PWR jumper; ② Check cable direction (golden finger faces PCB front); ③ Set XCLK=20MHz in code.【High Compatibility and Wide Voltage Support】 ESP32-WROVER dual-core processor; 4.5V to 36V wide voltage input; Type-C USB interface; 3.3V regulated output; compatible with LabVIEW, MATLAB, and STM32
