ESP32-EVB, a development board based on ESP32, is widely used in different industrial and domestic aspects, such as WiFi smart phone, IoT, connected car, smart home, industrial control, medical, security and home automation, but mainly used in the areas of RF evaluation and development kits and boards. With its flexible feature, it can easily adapt to various IoT applications. The following will mainly introduce its application field and working principle.

Application Field of ESP32-EVB

The ESP32-EVB is a complete development board based on the ESP32 system-on-chip. This ESP32 board includes an integrated WiFi and Bluetooth system, a USB-UART bridge, several other peripherals, a PCB antenna, and up to 40 GPIOs. This board is used to evaluate all the features of the ESP32. It is ideal for prototyping a wide range of applications, including embedded systems, IoT, home automation, Smart Phone, and automotive applications.

It contains two independent cores that can run simultaneously, an embedded Wi-Fi 802.11b/g/n transceiver, Bluetooth Low Energy Module, Audio and Video Coding, and other advanced features. It is also capable of high performance and low power consumption. The board also enables users to develop and debug applications using the Arduino IDE, while providing an easy way to self-developed algorithms and applications via the ESP-IDF.

Working Principle of ESP32-EVB

When the ESP32-EVB is powered, its two independent cores are started up sequentially. The first core, the Wi-Fi/BT processor, sets up a Wi-Fi connection with an access point. It also sets up multiple Bluetooth connection profiles for multiple Bluetooth devices. The Wi-Fi/BT processor then captures packets of data from these Bluetooth or Wi-Fi networks. The data is then sent to the second core for processing. This second core, the RTOS processor, carries out the necessary computations and algorithms on the data that was received.

The RTOS processor can also connect to the device’s I/O and open up access to a wide variety of peripherals. When data needs to be sent or received with the peripherals, the RTOS processor sends the commands to the I/O. The processor then interprets the data coming in from the peripherals, carries out tasks as needed, and sends the data off to the Wi-Fi/BT processor to be sent back out to the connected networks.

The ESP32-EVB board is easy to use for developers as well as engineers and hobbyists. It provides out-of-the-box support for various peripherals including an LCD and touch control interface, motor control, camera interfaces, PWM, SPI, UART and I2C. With its powerful features, the ESP32-EVB provides a great platform for rapid prototyping and development of IoT applications, including connected cars, smart home systems, medical and industrial applications.

In conclusion, the ESP32-EVB has wide application in the field of RF evaluation and development kits and boards. It provides an easy to use platform with which to quickly develop applications with its powerful features. As the development of IoT technology is ever changing, the ESP32-EVB is sure to become ever popular as a development board for designers and engineers seeking to build innovative applications.
