Description: brand new and high quality. Feature: Thermocouples are very sensitive, requiring a good amplifier with a cold-junction compensation reference. This product does everything for you, and can be easily interfaced with any microcontroller, even without an analog input. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors and level shifting circuitry, all assembled and tested. Comes with a 2 pin terminal block (for connecting to the thermocouple) and pin header (to plug into any breadboard). SPI interfaces, high-speed transmission. Direct digital output temperature value, no amplifiers, no ADC. 14-bit resolution, 0.25 degree temperature accuracy. Thermocouple Breakout Board only, other accessories demo in the picture is not included! Specifications: Item Type: Thermocouple Breakout Board Measurement temperature range: -200-1350C Input voltage: 3-5V for DC Material: PCB Board Size: 20.3x20.3cm/7.9x7.9in Color: Blue Quantity: 1 Pc Warm Tips: Works with any K type thermocouple. K thermocouples have about 2C to 6C accuracy. Internal temperature reading. 3 to 5v power supply and logic level compliant! SPI data output requires any 3 digital I/O pins. Note: No retail package. Transition: 1cm=10mm=0.39inch Please allow 1-3mm error due to manual measurement. pls make sure you do not mind before you bid. Due to the difference between different monitors, the picture may not reflect the actual color of the item. Thank you! Package Includes: 1 x Thermocouple Breakout Board
