Espressif Systems ESP32 Microcontroller

The ESP32 is a popular series of low-cost, low-power system on a chip microcontrollers with integrated Wi-Fi and dual-mode Bluetooth. It was developed by Espressif Systems, a company that has significantly influenced the Internet of Things (IoT) landscape through its affordable and powerful hardware solutions. The architecture is primarily based on the Xtensa Dual-Core 32-bit LX6 microprocessor, though newer variants use RISC-V.

Technically, while the brand and design originate from Shanghai, China, the physical manufacturing of the silicon wafers typically occurs in Taiwan at TSMC (Taiwan Semiconductor Manufacturing Company). The chips are then packaged and distributed globally, serving as the backbone for thousands of smart home devices, industrial automation systems, and hobbyist projects. Ownership remains with the founding company, Espressif Systems, which is a publicly-traded entity on the Shanghai Stock Exchange.
