This allows the module to be used based on the self-contained power supply. The Arduino boards are all running with 16 MHz which means that the microprocessor can execute up to 16 million instructions per second. This may sound like a lot but when you consider that a simple setting digital pin to high can take over 50 clock cycles.
As a result, he made the ESP8266 give out a signal at 60 MHz, which corresponds with the frequency of the third channel on analog TV. On the other hand, many amateurs consider the ESP32 to be much more difficult to work with and prefer the older version of the chip. Whichever you pick, however, we believe that you will make things much easier for yourself by using the Arduino Programming Language. The battle of price will will the ESP based boards because they are very cheap around $7.
There are already some projects to code Rust for the “older” ESP32 cores, but all examples I have seen end in the “Hello World”/Blinky example. In my professional life I always had the luxury of kicking up the computationally difficult things to the system-on-chip and let a proper superscalar CPU take on the tough problems. Where things got dicey was a touch screen sensor that had to preprocess the data in order for it to fit in the narrow bandwidth of the pipe upstream. But I wasn’t able to find numbers and I’m not setup with any RISC-V stuff at the moment to check. My wild guess is 10% to 30% more area, based on intuition and experience and no real data.

Now, as we have created our project ‘ESP32 Blinking LED’ let us proceed further and learn how to save and upload the program code to our ESP module. In this tutorial, we will learn to program ESP32 and ESP8266 boards with VS code by using the PlatformIO extension available in visual studio code. As we have seen in previous tutorials, we have learned to program ESP32 and ESP8266 boards using various IDEs. So, if you’re making a simple IoT project, the ESP8266 might do the trick for a lower price. Additionally, because it is more recent than the ESP8266, not all software has been developed to take the most out of the ESP32 functionalities, there is less support, and more bugs. But on the long run these issues will be fixed, and there will be space for both boards.
In fact, between ESP8285 and ESP32, there is also an intermediate solution ESP8285. This is a great option if your project does not have enough memory or computing resources, but at the same time, ESP32 is redundant. At the same time, note that different manufacturers may vary module parameters, such as pin count and package form-factor. Affordable microcontrollers and convenient firmware development environments also contributed to this widespread use of proprietary IoT development. First, we will define LED to save the GPIO pin through which the onboard LED is connected i.e., GPIO2. To download and install the visual code editor IDE, click here. The ESP32 is much more powerful than the ESP8266, contains more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth.
Power Supply
ESP based boards are much faster with a clock speed of 52 MHz up to 160 MHz for the ESP32. So if you plan a big project with many operations you should go with the ESP based boards. Give the name of your project, the type of your development board and the framework. We have named our project ‘ESP32 Blinking LED.’ For the board, we have selected ‘DOIT ESP32 DEVKIT V1.’ The framework will be Arduino. You can use any other name according to your choice. If you want to use ESP8266 instead, choose it appropriately from the drop-down list in the board section. We will save this project in the default location which is set as Documents/PlatformIO/Projects.
ESP8266EX houses wifi SoC, 32 bit processor and on chip SRAM. It can be used as standalone application or as slave to host MCU. This page compares ESP32 vs ESP8266 and mentions difference between ESP32 and ESP8266 wifi based boards. Both similarities and difference between ESP32 and ESP8266 boards are also mentioned.
The clock speed of Pico’s CPU is 133 KHz whereas that of ESP32 is 240 KHz. Therefore the Arm Cortex-M0+ CPU is way too slower than 32 bits LX6 of ESP 32. The first commercial development boards featuring Espressif’s RISC-V-based ESP32-C3, a drop-in replacement for the popular ESP8266, have appeared on the market — costing as little as $4 a piece.

Of course, if you’re crunching numbers hard and using both cores of the ESP32, it’s in another league, and you know who you are. But if you’re running Arduino on the ESP32 and you’re not explicitly running the RTOS tasks yourself, or running MicroPython and not using threads, you’re probably running a single core on the ESP32 anyway. Modulo some small difference in having a free core to exclusively handle WiFi, you might not be much worse off with the C3. The charts show that when using an open access point the esp8266 uses less power than the esp32. ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process. Generally bad news for Arduino board user and good news for ESP boards. One without WiFi and one WiFi included on the board.
I think they the RISC-V as the default option with the S2 ULP. The S3 has it as it’s main core. I expect that the next chip will be dual core assuming they can find the appropriate open IP.
Some time ago, in the fall of 2015 to be exact, the Espressif team of developers launched an enhanced successor of the super-popular chip – the ESP32 and other modules based on it. The ESP8266 microcontroller from the Chinese manufacturer Espressif is one of the most popular solutions for IoT-based applications that works through a Wi-Fi receiver. It is intended to launch apps stored in its memory and makes a great foundation for quite advanced Wi-Fi device control systems. I2S (Inter-IC Sound), is an electrical serial bus interface standard used for connecting digital audio devices together. In this microcontroller comparison I compare in total 8 different boards and I give you my suggestion, which board to use based on different use cases.
For example, when using Wi-Fi, the ESP32 uses the WiFi.h library, whereas the ESP8266 uses the ESP8266WiFi.h library. You also have to take into account that the pinout of the ESP32 is different from the pinout of the ESP8266. ESP32 Pinout Guide; ESP8266 Pinout Guide; You need to take that into account when declaring your pins. I had prototyped such a thing using a small OLED display on the ESP8266, and had the code lying around, including the graphic display which is the same sort that is on my ESP32 board. This links to the guide 3D Printed LED Microphone Flag. This links to the guide Using IFTTT with Adafruit IO to Make an IoT Door Detector. This links to the guide Textable Sensor with FONA and CircuitPython.
Based on that data, you can find the most popular open-source packages, as well as similar and alternative projects. I hope this review helped you in understanding the difference between Raspberry Pi Pico vs ESP-32 and which board is the best for your IoT project.

We’ve got pre-production samples, and Espressif is still working on supporting all the features of the ESP32-C3 in the IDF. Heck, you can’t buy an ESP32-C3 module yet anyway, so we’re stuck looking into our crystal ball a little bit. But the murmurs about pricing similarly to the ESP8266 make us take notice, and it’s certainly a worthy upgrade even at a small price premium, if that’s what the market will bear. At the same time, the ESP32-C3 is fundamentally less capable than the ESP32, so it’s got to come in cheaper than that. With ESP8266 dev boards selling for $2 and ESP32 dev boards selling for $4, that doesn’t leave much wiggle room, and we suspect some folks will just pony up for the ESP32s.
- The Espressif ESP32 is a very feature centric development board.
- Also, a huge plus is the availability of two software development options for these controllers – through the native compiler and through the Arduino environment.
- NodeMCU first out of the gate with a pair of board designs, now available, built around AI Thinker ESP32-C3 modules.

- In this video you will see Raspberry pi pico comparison with arduino uno, nodemcu esp8266, and esp32.
The question is what should you compare this to; is it more an ESP32 or an ESP8266? The new “C3” variant has a single 160 MHz RISC-V core that out-performs the ESP8266, and at the same time includes most of the peripheral set of an ESP32. While RAM often ends up scarce on an ESP8266 with around 40 kB or so, the ESP32-C3 sports 400 kB of RAM, and manages to keep it all running while burning less power. Like the ESP32, it has Bluetooth LE 5.0 in addition to WiFi. To conclude the esp8266 and esp32 low-power wifi exploration the graph below summarizes the tradeoffs between the two microcontrollers and the two sleep modes.
Well my Frogger try ended up pretty bad, never could get it working right, however I did get it to display, so I guess that is something. That said, I have learned more in the last few minutes reading this page then I knew about this little sports car of devices. Again, thanks billions I shall go on reading the rest of your pages. I knew I had come on something good when I first found your pages a few years ago, and you keep the education going and going. GPIO 6 to GPIO 11 (connected to the ESP32 integrated SPI flash memory – not recommended to use). The ESP32 has 10 internal capacitive touch sensors.
These can sense variations in anything that holds an electrical charge, like the human skin. So they can detect variations induced when touching the GPIOs with a finger. These pins can be easily integrated into capacitive pads and replace mechanical buttons. The capacitive touch pins can also be used to wake up the ESP32 from deep sleep. It has a single core RISC-V 32-bit CPU @160 MHz and includes 400 kB of SRAM and 384 kB of flash built-in. The ESP8285 is similar to the ESP8266, but has built-in 1 MiB of flash. ESP-32 is a low-cost, low-power system on a chip microcontroller with integrated Wi-Fi and dual-mode Bluetooth.
Next, let us check the uses of these two microcontroller boards below. If we talk about the input supply voltage, Raspberry Pi Pico can operate from 1.8 to 5.5 V while the ESP32’s operating voltage ranges from 2.2 to 3.6 volts. This means that a Li-Ion battery(3.0-4.2V), as well as 2 x AA(2.0-3.2V) batteries, can be directly connected to Raspberry Pi Pico but both these primary batteries will not be supported in the ESP 32. The price of both the microcontroller boards is the same i.e $4 which makes both of these boards comparatively affordable. Both the microcontrollers boards are extremely good on the spec sheet.
This list contains a bunch of getting started and more advanced guides for using ESPHome. Technically, all ESP8266/ESP32 devices are supported by ESPHome. Browse other questions tagged esp8266 nodemcu esp32 espressif or ask your own question. The labels on the DevKit are io pin numbers of the MCU.
The operating voltage of the ESP microprocessors is 3.3 V compared to the Arduino operating voltage of 5V. If the boards are used while connected to the socket, there will be no difference in the power consumption because the current will be reduced to gather the same amount of power. In case of a battery powered use case the difference will be much greater because if the battery discharging curve falls below the operating voltage, the microprocessor will shut down. Microcontroller programming is usually done in assembler or C, although there are compilers for other languages, such as microPython or Lua. A key feature of the module is the ability to connect an external antenna through the U.FL connector. We will add here the presence of additional RAM data, which allows you to run the microPython programming language on the controller. This chip is convenient to use in conjunction with the ESP32 development module, which makes it easy to create rapid prototypes since you do not need to design your own PCB.
