However, many people think that the ESP32 is more difficult to deal with than the ESP8266 because it is more complex. Is a low-cost, low-power Microcontroller with integrated Wi-Fi and Bluetooth. It is the successor to the ESP8266 which is also a low-cost Wi-Fi microchip albeit with limited vastly limited functionality. Since 2003, Rantle East Electronic is a full service independent wholesale distributor of electronic components. We provide a complete and cost effective sourcing solution for OEMs, Contract Manufacturers, Service & Repair Organizations, Distributors, R&D Groups and other companies that require electronic components.

So that’s the difference between an SoC, RF module, and development board. Of course, the same concept applies to other chips, like the ESP32. Once you start getting microcontrollers that have little webservers inside them, then that’s a rather specialized need and a lot of RAM makes it way easier to code for. But I’d want a microcontroller with a LOT of RAM and a camera interface , then things start to step into the territory of system-on-a-chip. Maybe one with a lot of I/O pins because the microcontroller is gathering or translating a lot of external data.

I must have swapped architectures 30 times in the course of this testing, and it’s literally that simple. The ESP32-C3 shares the coding framework with the ESP32, some of the peripherals, and has about the same amount of memory. The RISC-V CPU of the C3 vs. the Tensilica cores in the ESP32 and the ESP8266. So we thought we’d put them through their paces and see how they stack up in terms of processing speed and overall power use. It does not have remote control access and lacks security.

The ESP8266 gives you access to any microcontroller via your WiFi connection. The ESP8266’s ability to host an application or offload all WiFi networking tasks is one of its most crucial characteristics. Even under the most demanding industrial situations, it can function dependably because of its exceptional sturdiness. A microcontroller is an integrated circuit that can be programmed to perform tasks independently of other devices. The Raspberry Pi Pico and the ESP32 are two of the most popular microcontrollers on the market. They are two small, low-power microcontrollers built on 32-bit dual-core CPUs that can be used to control electronics projects.

What are some examples of ESP32 projects?

It has an L bit processor backed with a storage space of 80KB. The good thing about this chip is its ability to integrate all the required Wi-Fi components. To make you a better choice, we are going to do a deep comparison between ESP32 vs ESP8266. At the end of it all, you will make a smart decision on which one you think is perfect for your device or project. You are a manufacturer building products that will use Wi-Fi modules. These are among the cheapest Wi-Fi microchip or modules that you will find in the market.

range of applications

We have experience in developing client software in the IoT field. Please note, if we compare esp8266ex vs esp8266 it means esp8266ex is a new version of 8266. ESP8266ex is the updated version, and now it is most commonly available. ESP8266EX is the revised hardware and architecture version from the early ESP8266. All these advantages in general give a unique combination of qualities.

Also, the Bouffalo BL602 in the PineCone seems to use SiFive’s E24 core. The JTAG debug interface is not remapable for obvious reasons – it has to stay put so that you can always reprogram the chip. What I mean is that the FPU is small compared to the memory array and other stuff on the chip. Yes the desire for FPU is mostly for DSP functionality, which is useful in a device like this. But I wasn’t able to find numbers and I’m not setup with any RISC-V stuff at the moment to check.

Use Security-Minded Development Practices

Other interesting https://traderoom.info/ for the new ESP32 processor include a touch sensor, and hardware PWM both of which are missing in ESP8266. While the Raspberry Pi is sometimes sold as part as of a turnkey kit, it often comes barebone, meaning you’ll need to add accessories include a 15W+ USB-C power supply and a microSD card. You will have to install an operating system, preferably Raspbian for beginner, on the latter using NOOBS installer.

When using a esp32 vs esp8266 access point the esp8266 and esp32 show roughly the same performance. The reason is that while the esp32 uses more power when active it completes the WPA2-PSK association more rapidly then the esp8266. The charts show that when using an open access point the esp8266 uses less power than the esp32.


The Raspberry Pi Pico is the first microcontroller board from the Raspberry Pi Foundation and is based on the RP2040 chip. It is not a full-fledged computer like the company’s previous offerings but a tiny microcontroller board similar to the Arduino. Yesterday I got a LILYGO® TTGO T-OI PLUS RISC-V ESP32-C3 V1.0. To profit of the low deep sleep current consumption in deep sleep the LEDs are not helpful. Can I switch off the LEDs during deep sleep by disableing GPIO or is there another possibility.


The comparison starts with the deep-sleep with periodic wake-up mode of operation. It is assumed that all the optimizations described in earlier posts are made, such as providing all the parameters to wifi.begin and wifi.config. The devices of the ESP32 Ethernet & Wi-Fi & BLE PLC controller family have an integrated 5 GHz Wi-Fi specific chip, called ISM43340. As you may know, the 5 GHz Wi-Fi band is an improved version of the previous ones, such as the 2.4GHz band, for example. The ESP32 is much more powerful than the ESP8266, comes with more GPIOs with multiple functions, faster Wi-Fi, and supports Bluetooth.

Is much more powerful than the ESP8266, with more versatile GPIOs, faster Wi-Fi, and support for Bluetooth. However, many people think that the ESP32 is harder to handle than the ESP8266 because it is more complex. On the contrary, in our opinion, programming the ESP32 is as easy as programming the ESP8266, especially if you plan to program it using the “Arduino language” or MicroPython. In general, the ESP8266 and ESP32 controllers do not compete with each other – they perform different tasks.

ESP32 has a better platform for programming as compared to ESP8266. It offers better documentation and libraries that make it easier to program and debug. Hardware security refers to the security measures used in a device to protect the user’s data. ESP32 comes with a wide variety of peripherals such as USB OTG, UART, I2S, CAN 2.0 interfaces, touch sensor interface and much more. On the other hand, ESP8266 is a single-core processor whose CPU runs to a maximum of 80MHz. There are 16 GPIO pins that can be used to control various sensors.

  • From there, a microcontroller can make requests to connect to Wi-Fi, connect to servers, and send or receive data.
  • A secure bootloader can help to prevent unauthorized code from running on a microcontroller.
  • Because humans have evolved to write more efficient codes with better compilers with more efficient instruction sets.
  • ESP microcontrollers are indispensable for prototyping IoT solutions and building fast projects for private use and in small business solutions with a short life cycle.
  • 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.
  • Would be great if esp32c3 also had a ULP (risc-v of course, though something simpler seemingly would be fine).

The ESP32 has a maximum range of approximately 300 meters. If the team is already familiar with ARM architecture, then using an SoC may be the best option. The ESP32 has a built-in Ethernet MAC that can be used to connect to an Ethernet network. The ESP8266 does not have a built-in Ethernet MAC and thus cannot be used with an Ethernet network. The ESP32 has a built-in CAN bus controller that can be used to connect to a CAN bus.

And while our results are definitely significant and repeatable in terms of power and speed, they’re not game-changing. If we really needed to crush floats, we’d go for a chip that’s better suited for the task like an STM32F4xx or STM32F7xx, or those brutal NXP/Freescale 600 MHz i.MX ARM7 chips in the Teensy 4.0. If you’re buying an ESP-anything, it’s because you want the wireless connectivity, and it’s good to know that you’re not giving anything away with the ESP32-C3 on the CPU speed. Because ESP32 contains additional functionality such as a CPU core, faster Wi-Fi, Bluetooth 4.0 , touch sensitivity pins, built-in Hall Effect sensors, and temperature sensors, it is superior to ESP8266.

ESP32 can interface with other systems to provide Wi-Fi and Bluetooth functionality through its SPI / SDIO or I2C / UART interfaces. Although it lacks several features, it suffices for the majority of simple DIY IoT projects. However, the GPIO mapping has some limits, and there may not be enough pins for what you want to achieve. The ESP8266 goes with APSD for the Bluetooth and VoIP applications coexistence interfaces. It also contains a self-calibrated radio frequency that allows it to work with all the conditions of operating and does not require any radio frequency parts. We stock an extensive range of components and also offer a free component sourcing service for our customers.

After completing a BEng at the University of Warwick, Robin moved into the field of online content creation developing articles, news pieces, and projects aimed at professionals and makers alike. Currently, Robin runs a small electronics business, MitchElectronics, which produces educational kits and resources. To compare the two different devices, it is best to tabulate the data to get a better idea of what each device can offer. Overall, both chips have their own advantages and disadvantages and it is up to the user to decide which one best suits their needs. Also, the software support for the ESP8266 is getting older if not outdated. It also has official support from Arduino, Raspberry Pi, and ESP-IDF which makes it a lot more accessible.

Many ESP32 development boards come with small cameras and it is said to be a very capable board. Whenever you think about adding WiFI or Bluetooth connectivity to a project, ESP8266 or ESP32 boards are the obvious, cost-effective choice. The downside is that the platform may be better suited for people with a higher knowledge of electronics and programming. It is an integrated antenna and RF balun, power amplifier, low-noise amplifiers, filters, and power management module. The entire solution occupies the smallest amount of space on the printed circuit board. This board is used with TSMC 40nm low power technology 2.4 GHz dual-mode Wi-Fi and Bluetooth chips, which have the best power and RF attributes, are safe, dependable, and scalable to a variety of applications.
