In addition to Wi-Fi, the chip incorporates Bluetooth 5 Low Energy (BLE)It is geared towards low-power connections with mobile devices, wearables, nearby sensors, or control devices. This opens the door for the board to function as a central or peripheral device in hybrid solutions that combine Wi-Fi for the cloud and BLE for local interaction.
Another very powerful point is the integrated support for Zigbee y ThreadThese are two mesh network protocols widely used in home automation and distributed sensor networks. The fact that the ESP32-C6 itself can work with these standards simplifies the design of compatible devices. smart home ecosystems modern, without the need to resort to additional modules or specific gateways.
In terms of memory, the ESP32-C6 features 512 KB of high-speed SRAM.16 KB of low-power SRAM and 320 KB of ROM for the chip's internal functions. On more advanced boards, this memory is supplemented by a generous external flash memory, such as 16 MB in the case of the ESP32-C6-Touch-AMOLED-1.8 or 8 MB in the ESP32-C6-DevKitC-1-N8. This external storage allows you to store complex firmware, graphic resources for the display, fonts, icons, and other types of data without running out of space for even the most complex projects.
ESP32-C6-Touch-AMOLED-1.8 board: architecture and key components
La ESP32-C6-Touch-AMOLED-1.8 from Waveshare It's a good example of how much functionality can be integrated into a compact size. This board is based on the ESP32-C6 SoC, and around it, an ecosystem of components has been built covering display, audio, sensors, storage, and power, designed for projects where user interaction and connectivity are paramount.
Regarding memory, this model combines the internal resources of the ESP32-C6 with a 16 MB external flash memoryThis extra capacity is invaluable for loading graphical interfaces with many elements, saving complex configurations, managing audio buffers, or storing sensor data for extended periods. In addition, there's a slot for microSD cards which allows for a massive increase in storage according to the needs of the project.
The motherboard's audio section is also quite well done. It integrates a ES8311 codec along with a microphone and a speaker Mounted directly on the PCB, these modules facilitate the creation of applications with voice input and output, sound notifications, message playback, or even small voice assistants without the need to wire additional modules.

The response time of the pixels in an AMOLED panel is very short, which allows for drawing fluid animations, progress bars, graphics, and state changes Without noticeable ghosting or lag. When it comes to setting up real-time dashboards, home automation indicators, or small industrial HMIs, this visual fluidity makes all the difference in the perceived quality of the final product.
The screen is governed by a specific graphics controller (for example, the SH8601)It communicates with the ESP32-C6 via a high-speed QSPI bus. This quad serial interface offers a good compromise between the number of pins used and available bandwidth, making it ideal for moving images and frequent screen updates without overloading the microcontroller.
For touch detection, the board incorporates a capacitive control chip such as FT3168 or FT6146This controller reads touches and gestures on the screen surface and communicates the information to the ESP32-C6 via an I²C bus. Thanks to this controller, it's possible to implement simple taps, swipes, virtual buttons, sliders, and even more advanced gestures if the software supports them.
The combination of these components makes it natural to use graphics libraries such as LVGL (Light and Versatile Graphics Library) LVGL is used to build modern interfaces with menus, icons, toolbars, graphs, and interactive widgets. It integrates well with ESP32 platforms and provides examples and templates that streamline development, preventing you from having to create everything from scratch.
Energy management, RTC, and physical connectivity
