1. Hardware-Level Conflict Resolution: The RF Switch Breakthrough：

• The Problem Solved: The notorious SPI bus conflict when integrating multiple modules (CC1101, SD Card, Display) is over. We’ve implemented a Hardware RF Switch that allows you to seamlessly toggle between RF modules.

• Plug-and-Play Stability: No more firmware hacks or complex pin remapping. Simply flip the switch to ensure stable, reliable operation across all integrated components.

• Minimal Wiring: Designed for simple connection to the ESP32-2432S028 (CYD) via a few dedicated lines ( 2x4Pin Cable, 1x5Pin Cable, 1xTF male Extension Cable), turning a complex DIY project into a clean, modular assembly.

2. Maximum Integration: All-in-One RF & Utility： This single PCB integrates every critical module the Bruce community demands, making it the most feature-complete companion board available:

If you have CYD (ESP32-2432S028) already, only need to flash Bruce-CYD-2USB firmware.
