Description

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 - we 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. We have adapted the classic Arduino OneWire and DallasTemp libraries to be MAX31850 compatible, so please click on those links to grab our libraries.
