Is MAX31855 Thermocouple Amplifier Compatible with Home Assistant (MicroPython)?
Electrical Specifications
Always confirm pin assignments against the manufacturer datasheet before wiring.
Compatibility Overview
Cold-junction compensated K-type thermocouple amplifier measuring extreme temperatures up to 1350C with 0.25C resolution.
Typical SPI Wiring Reference
Standard SPI signal names. This is a bus reference, not a pinout for this specific board — check the silkscreen and datasheet for its actual pin order.
Reference circuit only. A shifter is needed when the host and peripheral run at different logic levels — check both datasheets to confirm whether this applies to your pairing.
