“SP32 Built-in OLED Board (Wemos Lolin32): Pinout, Libraries and OLED Control” 这个模块买了很久,一直没用。因为之前一直在玩稚晖君开源的ESP32-PicoDK,不知道是因为笔记本电脑USB口电压过低还是电路焊接的有问题,经常出现无法烧录程序的情况,因此找出了这个模块,经测试用笔记本烧录程序没有问

randomnerdtutorials.com/esp32-pinout-reference-gpios/ The each ADC has a calibrated VREF associated with it. If the calibration is off you could expect ADC1 and ADC2 to give slightly different results. You might need to run a calibration to fix the eFuse VREF values. ...
You could also use 1 and 3 if you disable the use of Serial or 14,2&15 if not using SD More info: https://randomnerdtutorials.com/esp32-cam-ai-thinker-pinout/ Another option (which I have not actually tried yet) would be to attach a MCP23017 Bidirectional 16-Bit I/O Expander (...
I will see if I can track down if the pinout is different or something.. Maybe they are just counterfeit. 👍 1 kholia commented Jun 2, 2020 My camera says "TY-OV2640-V2.0"... But it stopped working after updating the ESP32 platform. @morrisho What error message are you seeing...
