SCADAdle is a portable SCADA testing device built for the Bonneville Power Administration to simulate multiple signal types simultaneously, replacing their existing single-input testing process. It uses an ESP32-C6 microcontroller with Zigbee wireless communication to coordinate modular input units, covering RTD, analog, and digital alarm outputs, all powered by a rechargeable battery system and controlled through a handheld LCD remote. The team successfully delivered a working, fully wireless multi-input test system, though future work should address a short in the power delivery PCB and parasitic power draw from certain components when the system is off.
