ESP32 vs ESP8266 Which is Better?


Programmable I/O is an incredibly powerful feature, and you should consider opting for the Raspberry Pi Pico if you need it in your projects. Both microcontroller boards have dual-core CPUs and are capable of running more than one process at a time. However, tasks run on the ESP32 should be completed faster than the Raspberry Pi Pico, all other things being equal. Designed by Espressif Systems, the ESP32 is the successor to the ESP8266 microcontroller and offers a number of improvements over it. These include a faster processor, faster Wi-Fi, Bluetooth connectivity, more GPIO pins, and several other features.

Both boards can be programmed with the Arduino core using Arduino IDE or other supported IDEs. Although you can program both boards using Arduino IDE, they might not be compatible with the same libraries and functions. Some libraries are just compatible with one of the boards. This means that most of the time, your ESP8266 code will not be compatible with the ESP32. However, usually, you need to make a few modifications. ⚠️ On-board flash chip is unusually small , and this may be extremely limiting.

I have started a new project to use the ESP8266 based on the knowledge gained from the tutorials. I do not see anything in the drive letters, or devices that indicate an ESP32 is connected. As an old grey-beard I feel compelled to point out that one of the true great features of VSCode is the git integration. Being aware of and using source control is one of the things that separates professional developers from hobby coders.

At the same time, note that different manufacturers may vary module parameters, such as pin count and package form-factor. Let’s take a look at one of these families of microcontrollers from the Espressif company. But in the long run, these issues will be resolved and both boards will have room for their respective applications. Also, since it’s newer than the ESP8266, not all software was developed to take full advantage of the ESP32’s capabilities, so there’s less support and more bugs. While it doesn’t have as many features, it works well for most simple DIY IoT projects.

  • The ESP32 has a faster instruction rate than the RP2040 chip in the Pico.
  • You can also of course generate arbitrary wave-forms on all output GPIO pins, up to a limit of all pins .
  • Or, if you select “huge app,” you’d get just one partition of 0x or 3,145,728 bytes for your program and just 0xE0000 or 917,504 bytes for SPIFFS, but you wouldn’t be able to do OTA.
  • It’s more versatile and has more features like bluetooth, different wakeup sources, lots of peripherals and more.
  • At its heart, there’s a dual-core or single-core Tensilica Xtensa LX6 microprocessor with a clock rate of up to 240 MHz.

I’ve un PIO, and reinstalled, I uninstalled VScode and reinstalled, nothing seems to work. I’d like to complete this course, but I’m dead in the water right now. I don’t think I want to import many of my Arduino projects into PIO. Converting .ino files and backtracking its libraries is a little bit of a pain. Going forward, on new projects, I will start using PIO instead of the arduino IDE, and I’ll give it a shot. But, the LED_blink example is a big help, and you guys have made implementing PIO pretty easy.

We cannot compare esp32 vs 8266 directly, they are just designed to do different jobs, like a shovel and excavator.

Alternatively,real-time chat via IRCis a great way to converse with others, learn new things, and sometimes get answers to questions on the spot. So, if you ask a question in the IRC channel, try to stick around, as it might take someone awhile to respond. ESP32 chips with embedded flash do not support the address mapping between external flash and peripherals. There’s no competition here as both boards have a wide range of supported languages, and you can get pretty much anything done as long as you are not afraid to dig around a bit. According to the datasheet, the Raspberry Pi Pico consumes about 91mA during the popcorn test with power-saving disabled.

The esp32 vs esp826632 has a slightly more powerful processor, with a clock speed of up to 240 MHz, compared to the Raspberry Pi Pico’s maximum clock speed of 133 MHz. The ESP32 has a faster instruction rate than the RP2040 chip in the Pico. On the other hand, the rapid proliferation of Espressif microcontrollers has increased not only their cost but also the availability of integration with the popular Arduino IDE development environment. It has Wi-Fi and Bluetooth radio channels, a dual-core microcontroller, a rich set of built-in peripherals, and is a certified “FCC part 15.247”.

The two core architecture seems a bit of a double edged sword then. Better performance with two cores but the additional infrastructure to pull it all together complicates it. Part of the reason I thought about moving toward the ESP32 is because it is the newer device phasing out the older. I really don’t see the need for higher performance though in my applications, probably overkill. I’ll have to think how important it is to keep up with the evolution.
