This project involves designing a portable device that can inject a 1kHz sine wave signal into a 100V audio line to detect short circuits. The device should be compact (around the size of a smartphone) and include LED indicators to show the status: a green LED for normal operation and a red LED for short-circuit detection. The device will be powered either by a switching power supply or rechargeable batteries.
This is a ESP32-C3-WROOM-02U reference design based on the manufacturer's recommendations. On board we have an ESP module, USB C for firmware, 2 connectors with IOs and RGB LED
