Stable readings
Much less noise compared to older modules I have used. The onboard TL431 reference really helps with stability.

Good value
Works well for the price. The pins are a bit close together so careful soldering is required for headers.

Great for weighing projects
Used this for a kitchen scale project and it worked flawlessly. The SPI interface is much faster than I2C alternatives.
Q: Does it support 4-wire load cells?
A: Yes, it supports standard 4-wire bridge sensor configurations commonly used in load cells.
Q: Is 3.3V logic safe to use?
A: Yes, the module operates within a 2.7V to 5.5V range, so 3.3V logic levels are safe.
Q: Is this compatible with ESP32?
A: Yes, it is fully compatible. You can connect it via the SPI pins on the ESP32.
Q: Can you recommend a library?
A: There are several open-source libraries available on GitHub specifically for the CS1237 chip.
Q: What is the maximum sampling rate?
A: The data update rate is selectable between 10SPS for high resolution or 80SPS for faster reading.
