Documentation could be better
The hardware works fine, but the pinout diagram on the box was a bit unclear. Had to look up online examples to confirm the VCC and GND positions.

Essential for battery monitoring
I bought three of these for different projects. They are compact and reliable. The voltage division is handled internally which saves space on my PCB.

Perfect for Arduino Projects
This module works exactly as described. I used it to monitor a 12V battery system and the readings are stable. Easy to connect with standard jumper wires.

Good accuracy, slight noise
Overall a solid sensor. I noticed a little bit of noise in the analog reading when near a motor, but adding a capacitor fixed it. Good value for the price.

Fast shipping and works great
Arrived quickly and was well packaged. Integrated it into my solar charge controller project without any issues. Highly recommend for hobbyists.
Q: What is the maximum DC voltage this module can safely measure?
A: The module is designed to measure DC voltage up to 25V. Please do not exceed this limit to avoid damaging the sensor.
Q: Does the package include connecting wires?
A: The module comes with header pins installed, but jumper wires are sold separately. Standard 2.54mm pitch wires will fit.
Q: What is the power consumption of this module?
A: The module consumes very little power, typically less than 10mA during operation, making it suitable for battery-powered projects.
Q: Is this compatible with 3.3V logic boards like ESP32?
A: Yes, the operating voltage range is 3.3V to 5V, so it is fully compatible with 3.3V logic microcontrollers.
Q: Do I need to calibrate the sensor before use?
A: The module is pre-calibrated at the factory. However, for high-precision applications, you may apply a software offset in your code.
