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 ...
There is RTC GPIO support on the ESP32. The GPIOs routed to the RTC low-power subsystem can be used when the ESP32 is in deep sleep. These RTC GPIOs can be used to wake up the ESP32 from deep sleep when the Ultra Low Power (ULP) co-processor is running. The following GPIOs ca...

In the next step, the LED turns off for one second which means GPIO22 goes to an active low state The above two steps keep repeating as shown below: LED Blinking Connection Diagram As you can in the above pinout diagram of ESP32, we have a total of 36 GPIO pins, but we will be ...

https://randomnerdtutorials.com/esp32-pinout-reference-gpios/ 接入继电器之后,却不能控制其闭合或者断开(水位传感器也是,单独供电时,传感器信号没能正常传入ESP32) 原因分析: ESP32的GPIO引脚最高输出为3.3V电压,无法驱动继电器工作。继电器本质上依赖电压高低差而实现电磁的吸合以及断开 ...

BUSY --> (IO11)-IO11默认配置为SPI-FLASH的VDD,需解锁配置为GPIO使用。如不考虑解锁,可选择右侧IO,但后期存在复用冲突风险。 按以上配置,且IO11解锁后,接线示意如下: IO11解锁教程可参考: 打酱油的工程师:ESP32C3解锁使用IO11 功能1:基于墨水屏的日期显示; 初始化: V1003版本SOC下,墨水屏初始化前需要先初...
