In case you had a look at our page on the Arduino<\/a>, you probably wondered about its usability, if it doesn’t have connectivity. Arduino is meant to act as the core of local robots that do not need to communicate. If you have a need to work with your device remotely, or want to build an IoT device, then ESP32 is your tool of choice.<\/p>\n\n\n\n

ESP32 is a series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. The ESP32 series employs either a Tensilica Xtensa LX6 microprocessor in both dual-core and single-core variations, Xtensa LX7 dual-core microprocessor or a single-core RISC-V microprocessor and includes built-in antenna switches, RF balun, power amplifier, low-noise receive amplifier, filters, and power-management modules. ESP32 is created and developed by Espressif Systems, a Shanghai-based Chinese company, and is manufactured by TSMC using their 40 nm process. It is a successor to the ESP8266 microcontroller.<\/p>Wikipedia<\/cite><\/blockquote>\n\n\n\n

The first big difference between Arduino and ESP32 is the sheer amount of available memory. Arduino has 32 kilobytes, but even the most basic ESP32 has 4 megabytes. For the technically aligned, here’s some basic data:<\/p>\n\n\n\n
