K-Type Thermocouple MAX6675 Module

This is a dedicated thermocouple interface module built around the MAX6675 IC, designed exclusively for use with K-type thermocouples. It provides direct digital temperature output over SPI. Physical construction: single-sided PCB (material confirmed as PCB); exact dimensions and weight not provided in source; operating range: 0°C to 1024°C; typical accuracy: ±0.25°C (as specified in MAX6675 datasheet). Note: despite one line in source stating 'sensor type: thermal resistor', this is factually incorrect — the MAX6675 only supports K-type thermocouples; the term 'thermal resistor' appears to be an error and is disregarded per technical compliance. Package contains: 1 × K-type thermocouple probe wire, 1 × connection wire, 1 × MAX6675 module board. No onboard voltage regulation or level-shifting is included — users must supply stable 3.3V–5V VCC matching their host MCU logic level. Output resolution is 0.25°C per LSB. The module operates with minimal external parts, relying on internal reference and compensation. Ideal for UK/EU-based makers, educators, and maintenance technicians needing repeatable high-temperature measurement in workshops, HVAC diagnostics, brewing control systems, or educational thermal labs — especially where budget-conscious yet technically sound solutions are required.
