ESP32 (Original / WROOM1)

The ESP32 is a low-cost, low-power System-on-Chip (SoC) developed by Espressif Systems. It was first announced in 2016 and released to the public in 2017.

Technical Specifications The ESP32 features a dual-core 32-bit LX6 microprocessor running at up to 240 MHz, with a separate coprocessor for peripheral interfaces. It includes 520 KiB of internal RAM, as well as 448 KiB of flash memory and an additional 16 MiB of external SPI flash memory. The chip also features Wi-Fi (802.11b/g/n) and Bluetooth Low Energy (BLE) modules with support for BLE's SPP and GATT profiles.

Origins/History Espressif Systems, had previously developed several successful low-cost microcontroller products, including the ESP8266 Wi-Fi module. The ESP32 is an extension of this line of products and offers significant improvements over its predecessor, including increased processing power, memory capacity, and integration with additional peripherals such as Bluetooth Low Energy (BLE) and dual-mode 802.11b/g/n Wi-Fi.

XTensa Platform The ESP32's processor core is based on the XTensa LX6 microprocessor architecture, a RISC-V variant developed by Espressif Systems in partnership with Tensilica (now Cadence Design Systems). The XTensa LX6 provides a high level of instruction set compatibility with other RISC-V processors and offers improved performance and efficiency compared to previous ESP8266 products.

Relationship to Other ESP32 Products The ESP32 has spawned several variants designed for specific use cases/markets, and general platform updates, like a move to ARM. For more information on the ESP32 family or comparison chart, please refer to this page

Impact on the IoT World The ESP32 has had a significant impact on the Internet of Things (IoT) world, enabling developers to create affordable, low-power devices that can connect to the internet via Wi-Fi or BLE. Its popularity has led to widespread adoption in various applications, including home automation, industrial control systems, wearables, and robotics. The ESP32's open-source nature, as well as its large community of developers and a wide range of available libraries and tools, have contributed to its success in this field.
