USB-to-Serial Drivers (depending on the chip on your ESP32 board) Download the Arduino IDE from the official website. Install it following the instructions for your operating system.

Identify your ESP32 board's USB-to-Serial chip (usually printed on the board or found in product documentation). If you’ve ever ventured into the vast world of microcontrollers, you may have come across Arduino boards. Featuring a battalion of first and third-party boards, the Arduino series has a lot of following in the DIY tinkering landscape. Then there’s the Raspberry Pi Pico, a new microcontroller developed by the creators of the most popular SBC lineup. However, there’s an equally impressive microcontroller family that most beginners – and even intermediate tech aficionados – aren’t familiar with. By that, I’m referring to Espressif Systems’ offerings, specifically the ESP32 board.

So, in this article, I’ll go over everything you need to know before you pick this amazing development board for your next project. At the fundamental level, most ESP32 models are the same as Arduino and RPi Pico boards: they're microcontrollers that are useful for any DIY project involving heavy circuitry, robotics, or automation. Just like its rivals, the ESP32 doesn’t support a full-fledged desktop operating system, and the embedded OS of the ESP32 requires you to program the device using a code editor/IDE if you want it... Don't be fooled by their appearance — there's a world of difference between the tiny Arduino and Raspberry Pi boards! However, the ESP32 is far more powerful (at least, as far as microcontrollers are concerned) than its competitors, on top of possessing a more expansive IO pin configuration. Plus, many models of the ESP32 are equipped with built-in Bluetooth and Wi-Fi modules, a feature that’s only available on the more expensive Arduino and Pico versions.

Speaking of price, ESP32 is far more affordable than the other development boards, and even the cheapest version of the ESP32 will surpass its rivals in processing capabilities.
