This project monitors DC voltage and it's primary function is to report errors such as low voltage or over current scenarios via a capacitive touch screen, loads and threshold levels are set via the screen, connection between the screen and the relay controller is achieved by RS485 communication

12v load controller with RS485 WT32_SC01(ESP32S3) HMI

A low cost, low count modem to interface to any PC to send AT commands. UART to USB bridge used is CH340t to facilitate PC communication and features a single cell Lion charging circuit to charge a backup battery in case main supply fails
