For WIFI & BLE functionality, the Raspberry Pi Pico (2) W variant serves as the optimal choice, leveraging its integrated 802.11n Wi-Fi and Bluetooth 5.2 (BLE-compatible) radio modules to seamlessly extend the RP-Geeker's wireless protocol capabilities.

Additional functionalities can be implemented via modular expansion boards, designed to interface seamlessly with the core PCB through standardized pin headers—enabling protocol-specific add-ons (e.g., UHF RFID transceivers, Sub-1 GHz modules) to extend the system's capabilities while maintaining hardware scalability.
