Explore our extensive collection of articles, workshops, and tutorials to enhance your development journey with the latest tools and insights.” Dive into our latest workshops and master the skills you need to maximize the power of the ESP32. This user guide shows how to get started with ESP8266-DevKitC development board. 1 × PC loaded with Windows, Linux or Mac OS ESP8266-DevKitC is a small-sized ESP8266-based development board produced by Espressif. Most of the I/O pins are broken out to the pin headers on both sides for easy interfacing.

Developers can connect these pins to peripherals as needed. Standard headers also make development easy and convenient when using a breadboard. The following list and figure below describe key components, interfaces and controls of ESP8266-DevKitC board. Module soldered to the ESP8266-DevKitC board. Optionally ESP-WROOM-02D or ESP-WROOM-02U module may be soldered. This project brings support for ESP32 chip to the Arduino environment.

Espressif Systems is a fabless semiconductor company providing cutting-edge low power WiFi SoCs and wireless solutions for wireless communications and Internet of Things applications. We are the manufacturer of ESP8266EX.

A cost-effective and highly integrated Wi-Fi MCU for IoT applications Click the download icon on the right to get release notes in detail and download the SDK of the latest version. iRAM can be used as memory, thus saving about 17KB memory for user application. ESP8266_NONOS_SDK_V2.0.0_patch release notes This patch is based on ESP8266_NONOS_SDK_V2.0.0. While using it, users should use .a file in the package to overwrite the corresponding files subject to SDK/lib directory.

A cost-effective and highly integrated Wi-Fi MCU for IoT applications ESP8266EX is capable of functioning consistently in industrial environments, due to its wide operating temperature range. With highly-integrated on-chip features and minimal external discrete component count, the chip offers reliability, compactness and robustness. ESP8266EX is integrated with a 32-bit Tensilica® processor, standard digital peripheral interfaces, antenna switches, RF balun, power amplifier, low noise receive amplifier, filters and power management modules. All of them are included in one small package, our ESP8266EX. Engineered for mobile devices, wearable electronics and IoT applications, ESP8266EX achieves low power consumption with a combination of several proprietary technologies.

The power-saving architecture features three modes of operation: active mode, sleep mode and deep sleep mode. This allows battery-powered designs to run longer. The ESP8266EX microcontroller integrates a Tensilica L106 32-bit RISC processor, which achieves extra-low power consumption and reaches a maximum clock speed of 160 MHz. The Real-Time Operating System (RTOS) and Wi-Fi stack allow about 80% of the processing power to be available for user application programming and development.
