Great upgrade from standard SR04
The wide voltage range makes this perfect for both 3.3V and 5V microcontrollers. I2C support saves GPIO pins.

Perfect for ESP32 projects
Finally a sensor that works directly with 3.3V logic without level shifters. UART mode is very stable.

Good but needs careful wiring
Works well but make sure to check the jumpers for interface selection. Documentation could be clearer.
