Sunfounder HC-SR04 Case

thingiverse

The Sunfounder version of the HC-SR04 stands apart from most low-cost modules on the market. One key difference is its lack of an exposed crystal oscillator between the transmitter and receiver. Additionally, it features a socket that ensures wires are connected correctly. As a result, most existing HC-SR04 cases require significant modifications to accommodate this unique design. This particular case boasts a snap-fit design, allowing you to securely attach the backplate before snapping the front part into place.
