ESP
Are you familiar with ESP32 and ESP8266? What are the advantages of using an ESP32 or an ESP8266?
Espressif drives IoT development with a complete series of versatile, low-power, and secure Wi-Fi, Bluetooth, and combo chips. Popular products include the ESP8266 and ESP32 series of cost-effective chips, modules, and development boards. Both chips are equipped with a 32-bit CPU.
Shortly after the ESP8266 came out, NodeMCU, a low-cost open-source IoT platform was also released, foreseeing the popularity of these Espressif products. NodeMCU includes the firmware that runs on the ESP8266, and has the advantage of low power consumption, high memory, and built-in Wi-Fi. These solutions enable you to affordably control and monitor equipment remotely. Alternatively, if you do not require the ESP32/ESP8266’s wireless capabilities, you can use it to control inputs and outputs like an Arduino. However, you should be aware that, although the Arduino uses 5-V logic, the ESP32 and ESP8266 use 3.3-V logic, which means Arduino is a nice solution for many beginners.
The ESP32 is the successor of the ESP8266. It has an additional CPU core, faster Wi-Fi, more GPIOs, and Bluetooth 4.2 and Bluetooth low energy capabilities, among other things. The ESP32 also includes touch-sensitive pins that can be used to wake it up from a deep sleep.
The ESP32 chip comes with 48 pins with different functions. However, not all pins can be used on the ESP32 development boards. To make the pinout simpler and easier, pins with similar functionality are grouped together.
Want an ESP32, an ESP8266, or an associated product?
What makes ESP32 and ESP8266 so special? With low PCB requirements, ESP32/8266 delivers essential functionality and diversity to your projects. And why are they so affordable even though they offer a multitude of project options? The short answer is that the ESP32 and ESP8266 are inexpensive to manufacture. In addition to many of the currently available development boards, Elektor offers a variety of ESP-related kits (e.g., ESP32 Weather Station Kit) and bundles (i.e., development boards combined with a book), such as the Elektor ESP32 Smart Kit Bundle.
Which accessories are available for the ESP32 and ESP8266?
It is not easy or practical to use the ESP32 or ESP8266 chips for testing and prototyping. Most of the time, ESP32 and ESP8266 development boards will satisfy your requirements. These boards include all of the electronics necessary to power the chip and connect it to your computer. You also benefit from a helpful circuit for uploading code, pins for connecting peripherals, built-in power and control LEDs, and other handy features. Additionally, Elektor offers several books about ESP32 and ESP8266, including Getting Started with ESPHome, FreeRTOS for ESP32-Arduino, and The Complete ESP32 Projects Guide.
