Adafruit 1727 Thermocouple Amplifier with 1-Wire Breakout Board – MAX31850K

Brand: AdaFruit
Part Number: 1727
SKU: PPADA1727
Barcode: 5055421069537

The MAX31850K does everything for you, and can be easily interfaced with any microcontroller that has 1-Wire support. This breakout board has the chip itself, a 3.3V regulator with 10uF bypass capacitors all assembled and tested. This board can be used with ‘parasitic power’ – where the power is on the data line – or with ‘local power’ where the power for the converter comes in on the Vin Pin.

Please note: this board does not have level shifting on the 3V Data line – Adafruit did this on purpose so that it can be used in parasitic mode. The data line must be level shifted to 3V – our 4-channel shifter works wonderfully for level shifting 1-Wire and you only need one at the ‘1-Wire host’ for all thermocouples on the shared data line.

The MAX31850K data format is very similar to that of the well known 1-Wire DS18B20 temp sensor but it is not drop in compatible without code changes to check for the new ‘1 Wire family’ type. Adafruit have adapted the classic Arduino OneWire and DallasTemp libraries to be MAX31850 compatible, so please click on those links to grab the Adafruit libraries.

This breakout board comes with a 2 pin terminal block (for connecting to the thermocouple), 4.7K data line pullup resistor, and pin header (to plug into any breadboard or perfboard).

Not for use with any other kind of thermocouple, K type only!
