III. Key Features of the ESP32-C61-WROOM-1-N8R8
1. Dual-mode communication advantages, suitable for multiple application scenarios
The ESP32-C61-WROOM-1-N8R8 supports dual-mode communication with Wi-Fi 6 and BLE 5.3. Wi-Fi 6’s OFDMA and MU-MIMO features enhance concurrent transmission capabilities in high-density device scenarios, whilst spatial multiplexing technology increases overall network throughput by 35%; BLE 5.3 offers extended communication range and lower power consumption. Its automatic rate negotiation function adapts to diverse application requirements, meeting the high-bandwidth demands of smart home gateways and industrial control terminals whilst also supporting the long battery life needs of low-power sensors and portable devices. This makes it widely applicable across various IoT scenarios and forms the core foundation for the module’s high resale value.
2. High-Specification Storage and Robust Performance for More Efficient Development
ESP32-C61-WROOM-1-N8R8: A high-specification storage combination of 8MB Flash + 8MB PSRAM offers a significant advantage in its price range. It perfectly supports complex protocol stacks, data caching, audio processing and lightweight UI/graphics processing, resolving the performance bottlenecks caused by limited memory in traditional modules.
3. Low power consumption and high stability, suitable for harsh environments
The ESP32-C61-WROOM-1-N8R8 features an industrial-grade wide temperature range design (-40°C to +85°C), coupled with comprehensive ESD protection and low-power optimisation, enabling stable operation in harsh industrial environments and outdoor scenarios; With a deep sleep current as low as 1.8μA, combined with TWT wake-up technology, it significantly extends the battery life of battery-powered devices, making it widely applicable to off-grid equipment such as smart water meters, gas meters and outdoor sensors.
