In an era of increasingly complex IoT devices, developers face a core challenge: how to select a "wireless heart" for smart devices that meets high-speed, low-latency, long-distance requirements while being compatible with mainstream ecosystems? Chengdu EBYTE Electronic Technology Co., Ltd. offers a definitive answer: no need to choose—get all three. Its E105-WBS36 series modules embody this concept, integrating three cutting-edge wireless protocols—SparkLink (SLE), Wi-Fi 6, and Bluetooth 5.4—into a single SoC, providing unprecedented connectivity freedom and performance for next-generation smart hardware.

E105-WBS36 Series SparkLink Modules Overview

The E105-WBS36 series is not a single model but a complete product family tailored to different application scenarios, including:

  1. E105-WBS36S: Standard Performance Core Module

    • Wireless Protocols: SparkLink SLE 1.0 + Wi-Fi 6 (802.11ax) + Bluetooth 5.4 (BLE).

    • SparkLink Performance: Supports 1/2/4MHz bandwidth with a maximum air rate of 4Mbps; transmit power adjustable from -5 to 20dBm via AT commands.

    • Interfaces: 19 GPIOs, 3 UARTs, 2 I2Cs, 1 SPI, 1 I2S, 6 ADCs, 8 PWMs via pin multiplexing.

    • Antenna: On-board PCB antenna for high integration, ideal for cost-sensitive designs with sufficient space.

    • Range: Up to 1000 meters in open areas with a 5.0dBi external antenna.

    • The base and standard model of the series, integrating all tri-mode wireless functions.

  1. E105-WBS36SP: Enhanced Power Core Module

    • Enhanced RF Performance: While maintaining a 20dBm maximum transmit power, the built-in PA/LNA significantly improves actual output power, receive sensitivity, and link budget, ensuring better stability and anti-interference in complex environments.

    • Antenna: On-board PCB antenna with improved real-world communication performance due to the enhanced RF front-end.

    • Applications: Ideal for industrial sensing, high-end smart home, and other scenarios requiring high-reliability wireless connectivity in challenging environments.

    • Built on the S version, with integrated PA (Power Amplifier) and LNA (Low-Noise Amplifier) for SparkLink and BLE links.

  2. E105-WBS36S-TB: Rapid Development Evaluation Kit

    • Ready-to-Use: On-board USB-to-UART chip, Type-C power port, reset button, user button, and RGB status indicator.

    • Full Interface Access: Most functional pins (GPIO, UART, I2C, etc.) are exposed via standard headers for easy connection to sensors, actuators, or breadboards.

    • Value: Reduces hardware design, prototyping, and debugging time from weeks to minutes. Developers can start AT command testing, protocol switching, and transparent transmission verification with just a USB cable.

    • Entry-level development board with the E105-WBS36S module, designed to enable "zero hardware design" prototyping and evaluation.

Selection Guide:

  • For end products: Choose between E105-WBS36S (standard) and E105-WBS36SP (enhanced) based on RF performance requirements.

  • For learning, evaluation, and prototyping: Purchase the E105-WBS36S-TB development board.

Why Choose the E105-WBS36 Series? Four Core Advantages

  • True All-in-One Integrated Communication: One module solves all wireless connectivity needs. Devices can use SparkLink for ultra-low-latency, high-reliability local networking; Wi-Fi 6 for high-speed internet/LAN access; and Bluetooth 5.4 for direct connection to mobile devices. The three protocols can work independently or collaboratively, greatly simplifying hardware design.

  • SparkLink (SLE) Excellence: As a native Chinese next-generation short-range wireless technology, SLE offers significant advantages over traditional Bluetooth in latency (millisecond-level), reliability, synchronization accuracy, and anti-interference. The E105-WBS36 series combines SLE with mature Wi-Fi/BLE ecosystems, ensuring both technological forward-thinking and current product usability.

  • Simplified Development Experience: Unlike complex protocol stack development, the series encapsulates all three protocol stacks into a simple UART AT command interface. Developers can switch modes, configure network parameters, and enter "transparent transmission" mode via serial commands, enabling wireless data transmission like using a wired serial port with minimal learning curve.

  • Industrial-Grade Reliability: The full series supports a wide operating temperature range of -40°C to +85°C, with industrial-grade crystals and components, ensuring long-term stability in harsh industrial, outdoor, and automotive environments.

Typical Application Scenarios

  • High-End Whole-Home Smart Hub: Acts as a smart home gateway, connecting high-reliability, low-latency sensors and lighting devices via SparkLink; linking to the cloud and mobile apps via Wi-Fi; and enabling direct visitor phone connection via Bluetooth.

  • Industrial IoT Edge Gateway: In factories, collects high-speed, high-reliability machine sensor data via SparkLink; transmits data to servers via Wi-Fi; and allows maintenance personnel to debug devices via Bluetooth near-field connection.

  • Hybrid Smart Wearables: Syncs high-speed data with phones or other wearables via SparkLink; connects to headphones or reports health data via Bluetooth; and automatically backs up data to the cloud via Wi-Fi when in hotspot range.

  • Next-Generation Smart Home Appliances: Forms a low-latency control network with other home devices via SparkLink; receives cloud commands and performs OTA updates via Wi-Fi; and enables fast mobile device pairing via Bluetooth.
