It depends on the application and the development team’s expertise. In general, SoCs are more powerful but also more expensive. The ESP8266 is easier to use than the ESP32, but it’s not as powerful. The ESP32 is more versatile and can be used for a wider range of applications, but it’s not as easy to use. The ESP32 is a microcontroller unit (MCU), while the ESP8266 is a system-on-chip (SoC). This means that the ESP32 is a complete standalone device, while the ESP8266 requires an external microcontroller to function.
Others even come with extra hardware like specific sensors or modules, displays, or a camera in the case of the ESP32-CAM. Using ESP32 or ESP8266 bare chips is not easy or practical, especially when testing and prototyping. 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. All of these can happen through the same chip antenna on board. In parallel one core can be used with Bluetooth to do some operation another kit can be used simultaneously to control a stepper motor.
ESP32 VS ESP8266- Specifications
The onboard MicroB USB port provides power to the ESP32 development board. You can use the VIN pin to power the ESP32 and its peripherals directly via 5V external power supply. The ESP32 integrates an 802.11b/g/n HT40 Wi-Fi transceiver that allows to not only connect to a WiFi network to interact with the Internet but also to create its own network to which other devices can connect directly. WiFi Direct is also supported by the ESP32, which is a suitable alternative for peer-to-peer connections that don’t require an access point. It is easier to set up WiFi Direct and has substantially faster data transmission speeds than Bluetooth.
- This section will provide information about the CPU, clock, and speed-wise difference between ESP32 and Arduino Uno.
- Note that the pSRAM column refers to inclusion of additional
on-board pseudostatic RAM; this figure does not include the
SRAM within the ESP32 chip itself. - Build Web Servers with ESP32 and ESP8266 » boards to control outputs and monitor sensors remotely.

ESP 8285 with almost the same price provides more resources and performance, compared with ESP8266. ESP8285 has ultra-low power 32-bit MCU with 16-bit RISC core, and WiFi b/g/n/d/e/i/k/r connections. Affordable microcontrollers and convenient firmware development environments also contributed https://traderoom.info/is-xm-a-brokerage-we-can-trust/ to this widespread use of proprietary IoT development. ESP8266EX houses wifi SoC, 32 bit processor and on chip SRAM. It can be used as standalone application
or as slave to host MCU. Let’s compare both modules on the basis of Arduino IDE which are mainly used to program ESP32 and ESP8266.
HTTP vs MQTT – Which Communication Protocol Should You Use in Your IoT Application?
With the same functionality, the ESP8285 chip has a 1MB program memory operating in DUOT mode. ESP8266 power consumption is comparatively low for such solutions with WiFi. Also, it has a very good option to go into sleep mode, where power consumption is unbelievably low (1.0 mW). The family of ESP microcontrollers can be effectively used in IoT projects of varying complexity. 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.
The ESP32 adds an extra CPU core, faster Wi-Fi, more GPIOs, and supports Bluetooth 4.2 and Bluetooth low energy. Additionally, the ESP32 comes with touch-sensitive pins that can be used to wake up the ESP32 from deep sleep, and built-in hall effect sensor. Microcontroller programming is usually done in assembler or C, although there are compilers for other languages, such as microPython or Lua. Thus, from this day on all our of custom IoT platform projects will be used with the ESP32 which will be programmed in the Arduino IDE. The Arduino IDE will give us the option to use pre-made libraries which will make writing Internet-related code easier as well as simplify what is normally a very complex task.
How to Exchange Data between Arduino and ESP32 using Serial Communication?
This makes it one of the most affordable microcontrollers on the market. Other popular chips include the ATmega328P (Arduino Uno) and the ATSAM3X8E (Arduino Due). By following these best practices, you can help to ensure that your microcontroller-based system is as secure as possible.
- The ESP32 development board is actually cheaper than the Arduino board.
- The ESP32 can also connect to Bluetooth devices (including BLE), while the ESP8266 cannot.
- These components typically include a central processing unit (CPU), memory, input/output (I/O) interfaces and often a radio frequency (RF) transceiver.
- ESP32 is one of the evaluation boards with inbuilt sensors.
- Most of them only differ in form factor, price, and antenna design.
The Reset button, labeled RST and placed in the upper left corner, is used to reset the ESP8266 chip. The FLASH button is located in the bottom left corner and is used to upgrade firmware. A user-programmable LED indicator is also included on the board, which is coupled to the D0 pin. The board has an LDO voltage regulator to maintain the voltage stable at 3.3V, while the ESP8266’s operational voltage range is 3V to 3.6V.
What is Esp32?
The ESP32-based Wi-Fi/Bluetooth communication modules
in the table below are surface-mount devices (SMD). Each module is a
small printed circuit board upon which chips and other components are
soldered and treated as an inseparable assembly to be integrated onto
another PCB. All the modules listed below contain an ESP32 chip, a MHz crystal (clock), and a flash memory chip, but vary in
features such as antenna configuration, capacity of the flash memory
chip, and EM shielding. The ESP32 is a dual-core microcontroller with integrated Wi-Fi and Bluetooth. It has powerful processing power, memory, and peripherals compared to the ESP8266, making it suitable for complex IoT projects requiring more computational power.
What is the difference between ESP32 and ESP8266 module?
The ESP32 is an upgrade over the ESP8266 and includes 34 GPIO pins along with a 160 MHz Xtensa dual-core processor. A 32-bit processor, an ultra-low power co-processor, and several input/output ports, including digital-to-analog converters, are all features of the ESP32.
What is the advantage of ESP8266 over ESP32?
The ESP8266 is cheaper than the ESP32; The ESP8266 has a wider community (although we don't think that at this point, the difference is that big); For many IoT and Wi-Fi projects, the ESP8266 can do the job for a lower price; Both boards can be programmed using Arduino IDE or other supported IDEs.
