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...
Actually I could find that pinout picture before, but I was not able to identify the I2C pins ( pins not mentioned ... or I am blind ). I will get the dev kits tonight... let's start with GPIO8 and 9 you are welcome. yes, you're right, on this pin out no SDA, SCL on ...

In the pinout diagram of my 30-pin ESP32 Dev Module, only UART2 Port is free. I need to use UART1 Port. Data sheet shows that the IO lines of this port are associated with physical pin-28/29 (GPIO9/10) of ESP32 MCU). Currently, PPin-28/29 of ESP32 MCU are engaged with flas...

The I2C pins stated above are set in default. If we want to change the GPIO pins we have to set them in code. The diagram below shows the pinout for the ESP32. ESP32 I2C Pins Note: If we use other GPIO pins of ESP32 for I2C communication, we can define other pins inside our Ar...
By default, only UART0 and UART2 can be used. To use UART1, we have to redefine the pins because default pins of UART1 such as GPIO9 and GPIO10 are internally connected to the SPI flash memory. Also, on some ESP32 boards, they are even exposed on the pinout headers. Hence, we ...
