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 ...
•JTAG信号源–GPIO3 GPIO0、GPIO45和GPIO46在芯片复位时连接到芯片的内部弱上拉/下拉电阻器。 这些电阻器确定捆扎引脚的默认位值。此外,这些电阻器决定位 如果捆扎引脚连接到外部高阻抗电路,则值。 要更改位值,捆扎引脚应连接到外部下拉/上拉电阻。如果ESP32-S3被主机MCU用作设备,则捆扎引脚电压电平也可以由主...
In this tutorial, we will explore the pinout of the XIAO ESP32S3 and its related board, the XIAO ESP32S3 Sense, and learn how to use these pins for different purposes. Specifically, we will cover the usage of 1x UART, 1x lIC, 1x lIS, 1x SPI, 11x GPIOs (PWM), 9xADC, 1x ...
