+==ESP32-C2 General Information==
+The ESP32-C2 (ESP8684) ((https://www.espressif.com/sites/default/files/documentation/esp8684_datasheet_en.pdf)) family is a series of microcontrollers developed by Espressif Systems. It's based on the RISC-V architecture and is designed to offer ultra-low power and small size for various IoT (Internet of Things) applications. This family of microcontrollers has been designed to target simple, high-volume, and low-data-rate IoT applications, such as smart plugs and smart light bulbs. ESP32-C2 is also supported by Espressif's AIoT Private Cloud platform, ESP RainMaker® and supports Matter, a smart-home connectivity protocol that runs on any IP-supporting network stack.
+The ESP32-C2 microcontrollers come with several distinctive features:
+  * RISC-V Core: The ESP32-C2 is based on the RISC-V architecture, an open-source instruction set architecture (ISA). This differs from the ESP32 series' usual Tensilica Xtensa LX6 architecture.
+  * Connectivity:  Like other ESP32 modules, the ESP32-C2 features built-in Wi-Fi and Bluetooth 5 LE connectivity. This allows it to connect to the internet and communicate with other devices over short distances.
+  * Low Power Consumption: ESP32-C2, like other ESP32 variants, supports low-power modes, which is crucial for battery-powered and energy-efficient IoT applications.
+  * Rich Peripheral Interface Support: It includes a variety of peripherals such as UART, I2C, SPI, ADC, and more, making it versatile for different applications.
+  * Security Features: The ESP32-C2 family includes various security features, such as secure boot, flash encryption, secure storage, and cryptographic accelerators.

+===== ESP32-C6 =====
+==ESP32-C6 General Information==
+ESP32-C6 is Espressif's first WiFi 6 SoC integrating 2.4 GHz WiFi 6, Bluetooth 5.3 (Low Energy) and the 802.15.4 protocol. It is based on a high-performance (HP) 32-bit RISC-V processor, which can be clocked up to 160 MHz, and also has a low-power (LP) 32-bit RISC-V processor, which can be clocked up to 20 MHz. It has a 320KB ROM, a 512KB SRAM and works with external flash. The ESP32-C6, with its support for WiFi 6 and Bluetooth 5.3, can be a potential candidate for devices seeking to integrate into the Matter standard. Matter intends to create a universal standard for smart home devices to ensure interoperability and ease of use across different brands and ecosystems. Devices equipped with the ESP32-C6 can potentially comply with the Matter standard to ensure compatibility with other Matter-certified devices. They can be used to develop various other Matter-ecosystem solutions, such as Matter Gateways, Thread Border Routers or Zigbee Matter Bridges. However, adherence to the Matter standard involves hardware and software considerations, and manufacturers must ensure their devices meet the required protocols for certification.

+==ESP32-C6 Development Boards==
+There are not many prototype kits with ESP32-C6 SOCs on the market yet. Two sets released by the manufacturer deserve special attention. They are both entry-level development boards:
+  * Espressif - ESP32-C6-DevkitM-1 ((https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32c6/esp32-c6-devkitm-1/index.html))(figure {{ref>esp32_c6_devkitm}}), \\
+  * Espressif - ESP32-C6-DevkitC-1((https://docs.espressif.com/projects/espressif-esp-dev-kits/en/latest/esp32c6/esp32-c6-devkitc-1/index.html))(figure {{ref>esp32_c6_devkitc}}) . \\
