Features Thermocouple module, used to detect the temperature difference between the hot and cold ends. High‑quality amplifier with cold compensation reference, suitable for sensitive thermocouples. The distributor plate has a chip, and a 3.3V regulator with a 10uF bypass capacitor and a level conversion circuit. Comes with a 2‑pin terminal block (for connecting to a thermocouple) and a header (for inserting any breadboard or perforated board). Adopt for SPI interface, high‑speed transmission. The measuring temperature range is ‑200℃ ‑ +1350℃, 0.25℃ high accuracy, reliable use.
