The table below provides more information on pin usage, esp32 gpio, and please note the comments in the table for GPIOs with restrictions. For more infomation, please refer to ESP32 datasheet. Below is an example dump:.

The table below provides more information on pin usage, and please note the comments in the table for GPIOs with restrictions. For more infomation, please refer to ESP32 datasheet. For more details, please refer to ADC limitations. These pin functions can be used when:. The Ultra Low Power co-processor is running. Reset an gpio to default state select gpio function, enable pullup and disable input and output.

There are plenty of ESP32 boards out there with different pin arrangements. Here is a detailed pin diagram of 2 different ESP32 boards. It will be beneficial to know the specific functions of each pin:. Pinout of an ESP32 board. The goal is to inform you about the limitations of some GPIO pins of the ESP32 to avoid unpleasant surprises during your projects or having an incomprehensible bug in your code. ESPbased development boards typically have 33 pins except those for the power supply. Some GPIO pins have a little bit particular functionings:.

Thanks in advance.

However, there are a few things to keep in mind, so please read the pinout carefully. Please note that the following pinout reference is for the popular pin ESP32 devkit v1 development board. Not every ESP32 development board exposes every pin, but each pin works exactly the same no matter which development board you use. Although the ESP32 has 48 GPIO pins in total, only 25 of them are broken out to the pin headers on both sides of the development board. These pins can be assigned a variety of peripheral duties, including:. For convenience, pins with similar functionality are grouped together. The pinout is as follows:.

This can be very useful to control a relay, a thermostat, or any other device remotely. This project is also very versatile. Through your cloud dashboard, you can easily control more outputs without uploading new code to your board and you can even connect multiple boards to your server. There are many ways of controlling outputs from anywhere, and even though this is a working solution there are other methods that provide a two-way communication with your devices. I also recommend that you take this project further and add more features to fit your own needs. I recommend using one of the following hosting services that can handle all the project requirements:.

This indicates a common but annoying lack of insulation resistance thru the V mains power supply. Good info. I experimented and even use 0. See e. Hi Sara. PortB B pins are programed for input only analog signals. Hi Bob. One widely adopted solution Thank You for this excellent resource! Thanks for the nice overview. Thank you! It is strongly not recommended to reconfigure them for other application purposes. Thank you so much for your feedback. Remove from heat immediately, blow a lot. Hi Eva.

You can either get the complete course kit for this series of tutorials using the link down below. Or just refer to the table for the exact components to be used in practical LABs for only this specific tutorial.

Slowly increase heat not too slowly or also will damage by length of time until solder melts. The pinout is similar to the espmod and the footprint is the same. Again, thanks billions I shall go on reading the rest of your pages. It will be beneficial to know the specific functions of each pin:. Of course, I can verify myself. If you want to disable the interrupt of e. But the guide you refer does a great job explaining each individual pin. You guys are the best! Can you share what your project does? Here is an example that uses the second I2C bus:. Many are using it as a esp32 replacement for the mod. The pins highlighted in green are OK to use. There are two power pins: the VIN pin and the 3V3 pin.
