RF Pack S3 Dual-Band Module for M5Stack StickS3

Build Your Professional IoT Node with the Pingequa RF Pack S3 The RF Pack S3 is a professional-grade dual-band transceiver shield engineered specifically for the M5Stack StickS3. Engineered for Ultimate Stability We eliminated common DIY board crashing issues by integrating a dedicated SN74 Logic Buffer for precise SPI isolation. Combined with a customized LC filtering network, it ensures clean power delivery, preventing voltage drops and maintaining pure signal integrity during wireless evaluation. A Permanent Hardware Upgrade Designed to stay on your device forever, the top-mounted SMA layout keeps your handheld grip clear, while precision edge cutouts preserve full access to the StickS3's native Grove port. Hardware pins are natively routed (e.g., io0=CE) to match popular open-source ESP32 frameworks, delivering a true plug-and-play experience.

• [ Premium 4-Layer PCB & 50Ω Impedance ] Built with a solid reference ground plane for strict 50-ohm RF matching. It maximizes antenna efficiency and data stability for your smart home projects.
• [ Hardware SPI Isolation & Protection ] A built-in SN74 logic buffer actively arbitrates the MISO bus to resolve dual-module SPI conflicts. Integrated resistors protect your StickS3 from wiring faults.
• [ Top-Mounted Dual-Band Design ] Integrates Dual Band Design. The top-mounted SMA layout keeps the device compact and the bottom grip clear. (Note: Modules operate alternately).
• [ Tailored Fit & Permanent Mount ] Custom-sized for the StickS3 and secured via M2 screws for long-term use. Precision edge cutouts guarantee zero interference with the native Grove expansion port.
• [ Optimized for RF Protocol Analysis ] Built for open-source wireless evaluation, for true plug-and-play operation.
