一、ESP32 GPIO简介 1.ESP-WROOM-32 30 PIN 开发板 PINOUT 如果您跟我一样使用的是ESP32 30针开发板,您可以使用下面的GPIO图作为参考。ESP32 30针开发板GPIO引脚图 注:有几种开发板,如36针开发板和ESP32-Pico-Kit以及其他几种。我不在这里全部列出,但你可以使用这里的引脚定义作为参考。 2.ESP32的基本引...
Its a 38 pin ESP32 WROOM board. The pinouts (shown below) expose GPIO6-11, which are the SPI pins for SPI1, and which I've connected the PSRAM64H chip to. ESP32WROOM-38Pin-Pinout.jpg Any further thoughts/advice appreciated.
As mentioned earlier, the chip used with this board has 48 GPIO pins, but all pins are not accessible through the pinout of development boards. This ESP32 devkit has 36 GPIO pins and 18 on each side of the board as shown in the picture above. It has 34 GPIO pins and each pin has ...
Please refer below pinout for ESP32 with 38 Pin to build the schematic for this project. Refer our previous tutorial forInstalling the ESP32 Board in Arduino IDE?. Below schematic is for how to connect the MAX485 TTL To RS485 Module with ESP32 board. The connection forMAX485 TTL To RS485...

As you can in the above pinout diagram of ESP32, we have a total of 36 GPIO pins, but we will be usingGPIO22as a digital output pin. On different boards, these pins can be located at different locations. Therefore, you need to check its datasheet before using pin number in programmin...
[E][camera.c:1379] esp_camera_init(): Camera probe failed with error 0x20004 I'm fairly sure it's an AI-Thinker module, and that pinout worked last time. Do we conclude the camera is dead, or does anyone have any ideas for a better diagnosis?
