有無人用過呢款?
定我set 錯左esp32 version ? (ESP32-S)

這款轉接板需要按下 IO0 這個按鍵才能進入燒錄模式。

我都有試過,..但喺喺咩status按?
網上見到有人講見到 " ..... " 先按IO0
又有人話按住IO0 先load program ....
我試過哂都唔得...

- The ESP32-S2 chip needs to be in bootloader mode before it can be detected as a DFU device and flash. This can be achieved by pulling GPIO0 down (e.g., pressing the BOOT button), pulling RESET down for a moment, and releasing GPIO0.
另外Windows要先裝好driver?

似乎搞錯咗個ESP32-S對應個series,應該係ESP32(無內置USB-UART)而非ESP32-S2...

要接駁嘅係UART0 GPIO - 應該PCB另一面有label: RXD/TXD/3V3/GND 去 USB-TTL adapter
[着機->燒錄(download firmware)->燒錄完畢]期間要按實IO0,之後鬆開IO0再斷電

我都懷疑係....但我嬲嬲地,arduino IDE 所有esp32xx 既都試下...都係唔得

樓主可唔可以詳細啲講吓你點接駁同用邊款USB-TTL?
