Review on 🌡️ DROK Micro Digital Thermostat DC 12V: Temperature Controller Board with One-channel Relay and Waterproof Design by Derrick Milkie

Assembly works well in car radiators (replaces temperamental analog control). The product was delivered without documentation. By default, it is read in degrees Celsius. It would be nice to be able to swap out the terminal block and/or display to optimize the configuration. The relay is much taller than the display and causes legibility issues when placed flush in the case. It's nice to have tenths of a degree.
