Built around the ESP32-D0WDQ6, this WiFi Module / WiFi Development Board delivers flexible performance and low-power control so you can build reliable IoT products faster. Key benefits High-performance, adaptable CPU: Run the ESP32-D0WDQ6 at any clock between 80 and 240 MHz to match processing needs—boost speed for heavy tasks or scale back for efficiency. Granular power management: Control each of the two CPU cores independently or cut CPU power entirely while keeping peripherals active for monitoring, extending battery life in field devices. Broad peripheral support: Built-in capacitive touch, hall sensor, low-noise sensor amplifiers, Ethernet, high-speed SDIO/SPI, UART, I2S, and I2C let you connect sensors, storage, audio, wired networks and controllers without extra adapters. Easier development and connectivity: The CP2102 USB-to-TTL chip provides a stable serial connection for programming and debugging, simplifying the plug-and-play experience. What this solves Reduces development time by providing a ready set of interfaces and a reliable serial bridge for firmware upload and serial debugging. Balances performance and power use for battery-powered or always-on devices through clock scaling and per-core/power control. Enables mixed connectivity solutions (WiFi + Ethernet or SDIO storage + sensors) without adding multiple external modules. Technical highlights Core chipset: ESP32-D0WDQ6 Adjustable CPU clock: 80–240 MHz Dual-core power control: individual core enable/disable and full CPU power cut with peripheral monitoring retained Peripherals: capacitive touch sensors, hall sensor, low-noise sensor amplifiers, Ethernet interface, high-speed SDIO/SPI, UART, I2S, I2C USB-to-TTL: CP2102 for stable serial communication Practical use scenarios Battery-powered environmental sensor: Run one core for data acquisition and sleep the other, cut CPU power between readings while sensor amplifiers stay active to detect events and extend battery life. Smart home audio or voice interface: Use I2S for audio input/output, WiFi for cloud connectivity, and the ESP32’s variable clock to allocate processing for voice recognition or streaming as needed. Edge gateway or industrial controller: Combine Ethernet and WiFi for network redundancy, use SDIO/SPI for local storage or high-speed peripherals, and rely on the CP2102 for straightforward firmware updates and debugging. Compatibility and integration notes Designed for projects that use the ESP32 ecosystem and common serial interfaces; supports standard UART/I2C/SPI/I2S/SDIO workflows. The CP2102 provides reliable USB-to-serial communication for programming, logging, and development tools. This module is intended for developers building IoT devices that need flexible performance, fine-grained power control, and a wide set of built-in peripherals for rapid prototyping and deployment.
