Review on 🌡️ W1209 12V DC Digital Temperature Controller Board Micro Digital Thermostat -50-110°C Electronic Temperature Control Module with 10A Relay and Waterproof LED Display for Cooling Applications by Carlos Barete

This little board does a great job of controlling the server rack ventilation setup, the only downside is the lack of setup instructions. I was able to find videos online that explain proper wiring and setup to help me, but it would be nice to see something like this bundled with this product.
