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.

Most of the time, you’ll want to use ESP32 and ESP8266 development boards. These boards come with all the needed circuitry to power the chip, connect it to your computer, a circuit to upload code easily, pins to connect peripherals, built-in power and control LEDs, and other useful features. SiLabs CP2102Freematics ESPRIT is an Arduino compatible development board based on Espressif ESP32 with additional features for telematics projects.

This means that you can easily https://traderoom.info/ and monitor devices remotely via Wi-Fi or Bluetooth at a very low price. Build IoT projects and home automation gadgets with the ESP8266 Wi-Fi module. In MicroPython, most Python scripts are compatible with both boards . This means that most of the time, you can use the same script for ESP32 and ESP8266. The ESP32 supports Bluetooth communication protocol by default, while the ESP8266 doesn’t.

My issue was with importing Arduino IDE created files into Platformio. I have many many Arduino files and libraries and I was concerned with loosing or changing them to conform to Platformio and not being able to recover them. You can import older sketches into PIO, you just have to make a few changes, like adding arduino include and changing the .ino file to .cpp.

The ESP8285 module is a continuation of the ESP8266 line and has a higher degree of integration and reduced dimensions. With the same functionality, the ESP8285 chip has a 1MB program memory operating in DUOT mode. The microcontroller usually lacks a full-fledged operating system. It is designed to perform a range of tasks recorded in the firmware in the memory of the device. IoT was very much everywhere amongst radio amateurs, electronic engineers, and software engineers. Several open-source projects are now available on the Internet, which can be assembled in just a couple of hours.

The other 1,310,720 byte program space, “app1”, is not used by your sketch and is reserved for the next OTA update. After that next OTA update with the same size code, “app1” would be 61% used, and “app0” would be reserved for the next update. I am a retired professional and I avoid it because it simply is not necessary for Arduino projects and it is not suitable for posting on this forum or other “arduino’ish” forums. So, while you or I or most other folk can utilize IDF, most probably should not if they intend to identify with the Arduino community.

However, you can choose from many other models of development boards. Seeing all the above comparisons, ESP32 is by far better than ESP8266. As it leads in most of the features with a greater number of CPU cores, faster WiFi and Bluetooth support. And not only that it comes with double the number of GPIO pins compared to ESP8266.

The difference between esp32 vs esp8266 III.

For most Arduino-knowledgable users, the Official Espressif core for Arduino is more than adequate. For the ESP board I used the ‘Adafruit ESP32 Feather’ in the board selector. I installed VS CODE, PlatformIO IDE, I’m recording on DOIT ESP32 DEVKIT V1, everything works perfectly.


The Processor Cores column above lists number of cores for the central processor; this number excludes the ULP co-processor. SeeECO and Workarounds for Bugs in ESP32for differences between revision 0 and revision 1. For information on the ESP31B prototype/beta chip,visit the Historical page. ESP32-S0WDESP32-S0WD is a variation with a single-core (instead of dual-core) processor. The ESP32 SoC is housed in surface-mount, Quad-Flat No-leads packages in either 6×6 mm² or 5×5 mm² sizes with 48+1 connection pads . Physical package footprint/dimensions can be found in chapter 6 of theESP32 Datasheet.All ESP32 chips thus far have been manufactured using TSMC’s ultra-low power 40nm process.

I really wanted to go Linux but no matter which distro I tried, I don’t seem to get it right with VS CODE. Every time there is an error concerning the pins_arduino.h . I have even given up on using Linux though I could quickly install if someone showed me how to properly install VS CODE. I have followed this tutorial to the letter but still nothing doing. Yes I know I can select this module with the Arduino IDE, but in VS code with platformio plugin I can not select this board. It is very useful if you’re setting up a web server with separated HTML, CSS and Javascript files. You can program all the files using the same software and you can open the files side by side. It also allows you to upload the files to the ESP32 or ESP8266 filesystem easily.

Getting Started with VS Code and PlatformIO IDE for ESP32 and ESP8266 (Windows, Mac OS X, Linux Ubuntu)

While the ESP32 can cost around $6 to $12, the ESP8266 can cost $4 to $6 (but it really depends on where you get them and what model you’re buying).

Do you have the same guides for getting the ESP32 programmed for MQTT? The ESP32 has more GPIOs than the ESP8266, and you can decide which pins are UART, I2C, SPI—you need to set that on the code. This is possible due to the ESP32 chip’s multiplexing feature that allows you to assign multiple functions to the same pin. The ESP32 is a dual-core 160MHz to 240MHz CPU, whereas the ESP8266 is a single-core processor that runs at 80MHz. International System of Quantities notation is used to represent the measure of data described on this page. Notably, International Electrotechnical Commission definedbinary prefixes are used where appropriate; International System of Units definedmetric prefixes are used where appropriate.


Were I writing a commercial application, I would not hesitate to write it using the Espressif IDF libraries. The Arduino implementation is essentially wrappers around IDF code. I’d say move on with the project as-is, don’t have anxiety about problem you don’t have and are unlikely to have. Maybe even take advantage of FreeRTOS techniques as it’s loaded into the processor whether you use it or not. People create lots of large, sophisticated ESP32 projects without resource issues.

esp32 vs esp82662102Open source hardware ESP32-based Arduino Uno style development board with microSD card slot, DC power barrel jack, battery connector & charger, USB connector, and more. The boards don’t use the same code so you can’t compare the differences. If the code works, there are no bugs that need to be checked. Remember that the esp32 is a dual core chip and the ESP8266 is a single core chip. The ESP32 runs all it’s wifi function on one core while, by default at least, the arduino sketch runs on the other. There is a lot more code necessary to get that to work.

SiLabs CP2102NESP32-LyraTD-MSC (previously ESP32-LyraTD-MS1) is a circular board for audio playback & recording intended to be used in an “Alexa type” product. ESP32-LyraTD-MSC will be the first ESP32-Lyra board approved for public release. There have been several different ESP32-Lyra boards developed internally — varying in physical form and technical specifications.

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.

The ESP32 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”.
