Good value but warm
Does the job well for monitoring mains voltage. Gets a bit warm under continuous load but within limits.

Documentation could be better
Module works but the pinout diagram was slightly confusing. Had to test connections manually.
Q: Does it measure DC voltage?
A: No, this module is designed for Single-Phase AC only.
Q: Is galvanic isolation provided?
A: Yes, there is 2500V AC isolation between input and output.
Q: Can I use this with 3.3V logic?
A: Yes, but ensure the output signal matches your MCU tolerance.
Q: What is the max input voltage?
A: The module supports up to 300V AC input safely.
Q: How do I calibrate the output?
A: Use the onboard potentiometer to adjust the zero point and gain.
