What do you know about ESP32?

The ESP32 is a low-cost, low-power system-on-a-chip microcontroller family with built-in Wi-Fi and dual-mode Bluetooth. If you are familiar with the Arduino open-source microcontroller board, getting started with the ESP32 is not a big deal. Using Arduino, you can design and implement advanced projects. With ESP32, you can do even more sophisticated projects. However, do you know what features the ESP32 has? Great, let’s talk.

When compared with the Arduino boards, the ESP32 is a tiny microcontroller board. The ESP32 chip is even smaller, but it has incredible integrated processing power.

ESP32 Chip

In 2016, a Shanghai-based Chinese company known as “Espressif Systems” developed, and released the ESP32. This board is more powerful and has more features when compared with their ESP8266 board. There are various types of ESP32 boards on the market, and anyone can choose one by comparing the type of project they intend to develop with the type of ESP32 board.
