Realtek WiFi Module: Engineered for Robust Dual-Band Connectivity
In today’s crowded wireless landscape, reliable connectivity isn’t just a feature,it’s a fundamental requirement for successful product design. For engineers and OEMs developing solutions for IoT, Automasi Perindustrian, and smart retail applications, the Realtek W-iFi Module FSC-BW236 delivers a powerful, pre-certified wireless solution built around the proven RTL8720DN SoC. This compact module combines advanced dual-band Wi-Fi with Bluetooth® 5.0 in a complete system-ready package that accelerates development while ensuring reliable performance.
Engineered for Real-World Performance
The FSC-BW236’s dual-band Wi-Fi capability (2.4 GHz dan 5 GHz) with full 802.11 a/b/g/n compliance addresses the growing challenge of RF interference in connected environments. In practical terms, this means a wireless payment terminal in a busy retail store can maintain stable transactions on the less-congested 5 GHZ Band.
The integrated Bluetooth 5.0 functionality extends design possibilities beyond simple Wi-Fi connectivity. Engineers can implement BLE for device provisioning,allowing end-users to easily configure Wi-Fi settings through smartphone apps. This dual-radio approach provides the flexibility needed for modern connected products.
Beyond Basic Connectivity: A Complete Embedded Platform
What truly distinguishes the FSC-BW236 is its integrated dual-core architecture, featuring an ARM Cortex-M4F for application processing and a Cortex-M0 for power management. This enables developers to run custom firmware directly on the module, processing sensor data and managing device logic without requiring an external microcontroller. For battery-powered devices, this integration means smarter power management—the module can handle complex tasks during active periods while dropping to deep sleep currents as low as 10 µA during idle states.
The module’s comprehensive peripheral set includes UART, I2c, SPI, PWM, and USB interfaces, supporting diverse applications from environmental sensor networks to motor control systems. Each interface is designed with real-world implementation in mind, featuring configurable pull-up resistors and drive strength settings that simplify board design.
Deployment-Ready for Demanding Environments
The FSC-BW236 demonstrates its engineering maturity through robust environmental specifications. The industrial-temperature variant (FSC-BW236C) operates from -40°C to +105°C, making it suitable for applications ranging from solar inverters in desert installations to outdoor monitoring equipment in cold climates. This thermal resilience ensures consistent performance where lesser modules would fail.
Multiple antenna options including onboard, IPEX connector, and stamp-hole designs,provide mechanical flexibility for different enclosure types and RF requirements. For developers, this means the ability to optimize antenna performance for specific installation scenarios without redesigning the core module.
The module’s comprehensive certification portfolio covers FCC, IC, CE, Kc, Telec, and SRRC requirements, significantly reducing the time and cost associated with regulatory compliance. This pre-certification is particularly valuable for startups and enterprises alike, accelerating time-to-market while ensuring global market access.
Proven in Diverse Applications
Across industries, the FSC-BW236 has demonstrated its versatility. In wireless POS systems, it provides the stable, secure connectivity essential for financial transactions. Industrial sensors benefit from its ability to maintain connections in electrically noisy environments while withstanding temperature extremes. Smart printers leverage the dual-band capability to ensure reliable mobile printing even in crowded office Wi-Fi environments.
For engineering teams seeking a reliable Realtek WiFi module that integrates dual-band Wi-Fi, Ble 5.0, and application processing in a single certified package, the FSC-BW236 represents more than just a connectivity solution,it’s a foundation for building the next generation of connected products. With its combination of performance, fleksibiliti, and deployment readiness, it eliminates the traditional compromises between wireless capability, development complexity, and time-to-market constraints.
