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...
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 ...
