Description

The US-025 / US-026 ultrasonic ranging module can achieve the non-contact ranging function of 2cm~6m. The working voltage is 3v-5.5v and the working current is 5.3ma. It supports the GPIO communication mode and works stably and reliably.

The us-025 and us-026 have the same performance, size and principle.

The difference between:

Us-025 USES double panel, us-026 USES single panel;

The 4Pin row of us-025 is welded on the front side (probe side), us-026 is a single panel, there is no welding pad on the front side (probe side), and the welding pad is welded on the back side (chip side).
