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 ...
16pin的typec 使用签子涂抹焊锡膏,焊接16pin的typec引脚,在焊接时先焊接底座的引脚(因为我的电烙铁功率不够大,先焊接外接引脚,只能加热部分引脚,容易跑偏、焊歪) 少涂焊锡膏,在焊接时用电烙铁向四周刮,防止连锡 相关知识:16p typec D- D+ D- (Data Minus): This is one of the data lines. It carrie...
Which GPIO Pins should I use ? ESP32 Pinout Reference: Which GPIO pins should you use? 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...
Enable (EN) is the 3.3V regulator’s enable pin. It’s pulled up, so connect to ground to disable the 3.3V regulator. This means that you can use this pin connected to a pushbutton to restart your ESP32. GPIO current drawn The absolute maximum current drawn per GPIO is source 40mA ...
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 ...
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...
