Getting Started with the ESP32 Development Board

ESP32 is more powerful than ESP8266, contains more GPIOs with multiple functions, faster Wi-Fi, and also supports Bluetooth. Many people think that ESP32 is more difficult to handle than ESP8266 because it is more complicated, but in fact ESP32 programming is as easy as ESP8266, especially Arduino language or MicroPython. The ESP32 is much more powerful than the ESP8266, comes with more GPIOs with multiple functions, faster Wi-Fi, and supports Bluetooth. However, many people think that the ESP32 is more difficult to deal with than the ESP8266 because it is more complex. On the contrary, in our opinion, it is as easy to program the ESP32 as the ESP8266, especially if you intend to program it using the “Arduino language” or MicroPython. ESP32 https://traderoom.info/brainwagon-the-esp32-vs-the-esp8266/ provides remote control access and temperature sensor.

The ESP8266 is a low-cost Wi-Fi microchip with a built-in TCP/IP stack and microcontroller capability, released in 2014 by Espressif Systems in Shanghai, China. The choice between the two boards depends on your specific needs, as each offers distinct advantages and drawbacks. Furthermore, the ESP32 incorporates 10 capacitive sensing GPIOs capable of detecting touch, facilitating event triggering, or waking up the ESP32 from a deep sleep, among other applications. The ESP8266 stands as a comprehensive System-on-a-Chip (SOC) circuit, functioning as a self-contained Wifi module equipped with an IP/TCP protocol stack. Through your Wifi connection, the ESP8266 facilitates access for any microcontroller. Many people who aren’t familiar with electronics often struggle to differentiate between ESP8266 and ESP32.

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. When the ESP8266 draws up to 80mA during RF transmissions, it can reliably supply up to 600mA, which should be more than enough. The onboard MicroB USB connector provides power to the ESP8266 NodeMCU.

Built-in Sensors

The ESP8266 and ESP32 system-on-chip (SoC) microcontrollers serve as Internet communication devices for builders, yet the ESP32 stands out. While the Arduino IDE is capable of directly programming the ESP8266, it often presents more challenges compared to the straightforward programming of the ESP32. The ESP32’s faster processor and increased memory capacity enable the development of significantly larger projects on a single SoC. Additionally, the ESP32 boasts robust security features, enhancing its overall device security. While using the ESP32, you may not need to use an additional micro-controller as the ESP32 has dual 32-bit microprocessors and will run on breakout boards and modules from 160 MHz up to 240MHz.

In general, ESP32 has better performance, but ESP32 is more expensive than ESP8266. If you only need to make a simple IOT project, then ESP8266 is completely sufficient. Both development boards have their own application space, and the one with a higher price ratio can be selected according to the needs of the project. The prices of both chips are very cheap, but the cost of ESP32 is slightly higher. In addition, due to the long time to market of ESP8266, more support can be obtained in terms of software, which will be more convenient and compatible to use.

2. Although some find it more complex, especially compared to the ESP8266, programming the ESP32 can be straightforward, especially when utilizing the Arduino language or MicroPython.
3. The ESP32 chip adds additional CPU cores, faster WiFi transmission technology and more GPIOs, and supports Bluetooth 4.2 protocol and Bluetooth Low Energy.
4. These include a faster processor, faster Wi-Fi, Bluetooth connectivity, more GPIO pins, and several other features.
5. After that, just use heat shrink tubing to close protect the wiring and caulk or hot glue to close up the grommet hole.

Even ESP8266 is overkill for that but it nearly costs nothing.I prefer the ESP but compared to NodeMCU devices you need some more parts to wire it and an FTDI for initial flashing. 01ESP32 has one more CPU core than ESP8266, faster Wi-Fi, more GPIOs and support for Bluetooth 4.2 and Bluetooth Low Energy. In this article, we will compare the ESP32 vs ESP8266 and cover the pros and cons of each board.

6. Although it doesn’t have as many functionalities, it works just fine for most simple DIY IoT projects.

It closely resembles conventional Python, implying that if you possess proficiency in Python programming, you inherently possess the skills to program in MicroPython. The ESP32 surpasses the ESP8266 in terms of GPIO count, affording you the flexibility to designate specific pins for UART, I2C, and SPI functionalities by configuring the code. This capability stems from the ESP32 chip’s multiplexing feature, enabling the assignment of multiple functions to a single pin. The primary role of the ESP8266 is to either host applications or offload all Wifi networking functions. Its remarkable durability allows it to consistently operate even in challenging industrial environments, owing to its wide operating temperature range.

The ESP8266 module provides powerful onboard processing and storage capabilities, allowing it to be integrated with sensors and other applications. In summary, for simple, low-power Wi-Fi-based projects, the ESP8266 is the preferred choice. On the other hand, if you need more processing power, extra memory, and features like Bluetooth, the ESP32 is the clear winner.

Both the ESP8266 and ESP32 are supported by the Arduino IDE and the native ESP-IDF (Espressif IoT Development Framework). The Arduino IDE is suitable for small projects, but for larger and more complex projects, it’s advisable to use the ESP-IDF through the Visual Studio Code extension or the Eclipse plugin. Both boards have advanced power-saving technologies to minimize power consumption effectively.
