A New Era of In-Vehicle Connectivity: Cut the Cables, Embrace Seamless Wireless
The wireless CarPlay adapter solution enables projecting your phone's CarPlay interface to the car's display via Wi-Fi, allowing you to safely use your phone while in the car. While focusing on driving, you can still synchronize your phone's navigation software, music apps, make phone calls, use Siri voice commands, and send and receive messages.
In this case, the customer adopted a wireless CarPlay solution based on RTL8730E.
Wi-Fi 6 Dual-Band Ultra-Fast Engine: Redefining In-Vehicle Data Transmission Speed
- Revolutionary Wi-Fi 6 Efficiency: Ameba is among the first to deploy the 802.11ax standard in automotive environments. Leveraging OFDMA and MU-MIMO technologies, it dramatically boosts transmission efficiency and interference resilience while reducing network congestion—ensuring lightning-fast responsiveness even when simultaneously streaming HD navigation maps, music, and voice commands.
- Intelligent 2.4GHz & 5GHz Dual-Band: 2.4GHz delivers superior penetration for reliable connectivity, while 5GHz offers wider bandwidth and minimal interference. The system continuously monitors the in-vehicle RF environment and dynamically selects the optimal band—perfectly balancing stability and speed.

USB: The Rock-Solid Foundation for In-Vehicle Connectivity
- 480 Mbps High-Speed Throughput: Compliant with USB 2.0 High-Speed specifications, it delivers up to 480 Mbps bandwidth—more than sufficient for high-definition screen mirroring, lossless audio streaming, and other high-data-rate applications, ensuring smooth, stutter-free performance.
- Industrial-Grade USB Protocol Stack: Features a field-proven USB stack refined over years of real-world deployment. Rigorously tested across dozens of car brands and head unit models, it guarantees rock-solid, plug-and-play compatibility—eliminating dropouts and handshake failures.
- Flexible Dual-Mode Operation: Seamlessly switches between Host and Device modes to support diverse in-vehicle protocols and use cases—from smartphone projection to diagnostic tools—maximizing system versatility.
Bluetooth Dual-Mode Engine: The Intelligent Bond for Seamless Interaction
- Dual-Mode Coexistence, Immersive Audio Feast: Seamlessly supports both Classic Bluetooth and Low Energy (BLE) dual-mode operation. It offers full compatibility with mainstream protocols like A2DP and HFP while pioneering support for LE Audio technology. Whether streaming lossless HD stereo or managing low-latency calls, the system achieves seamless synergy to deliver a silky-smooth wireless audio experience.
- Independent RF, Ultimate Coexistence Performance: Features an innovative independent antenna design where Wi-Fi and Bluetooth utilize dedicated RF channels and antennas. This physical isolation significantly minimizes signal interference. Even during high-speed Wi-Fi throughput, the Bluetooth connection remains stable and drop-free, ensuring rock-solid reliability during multitasking.
- Full-Process Acceleration: A deeply integrated Wi-Fi & Bluetooth interface designed specifically for in-vehicle connectivity. It provides ultra-fast UUID response and efficient RFC APIs. The entire sequence—from device discovery, Bluetooth handshake, and Wi-Fi AP info exchange to the final Wi-Fi projection setup—is fluidly streamlined, ensuring a faster connection every time you enter the vehicle.
Minimalist Hardware Design: Power in the Palm of Your Hand
- All-in-One, Highly Integrated SoC: Integrates DDR memory and Flash storage on-chip—eliminating the need for external companion chips. This simplifies PCB design, reduces BOM cost, and improves manufacturing yield.
- Wide-Temperature Resilience: Operates reliably from -20°C to +85°C. Whether under a sun-baked dashboard or during sub-zero cold starts, performance remains unwavering—validated across thousands of real-world vehicles.
- Extreme Miniaturization, Ultra-Low BOM: Packs immense computing power into a package no larger than a fingernail, freeing up valuable PCB space. Achieving coin-sized form factors without compromise, this highly integrated solution delivers both premium performance and exceptional cost efficiency.
