MAX31855 Breakout

From McLEng

Single channel low-cost MAX31855 breakout board. This little guy has a min 2 pin screwless header to connect a type K thermocouple and two 3 pin 0.1" headers in a DIP format to interface to the chip. This is a very breadboard friendly breakout!

• NOTE: The while the MAX31855 is similar in function to the MAX6675 the MAX31855 is a 3.3V device. You must use a level shifter (included) to interface to a 5V system such as an Arduino. Connecting to 5V logic will damage the chip! MAX31855 with 5V

Comes as a kit with the following:

• Breakout board with MAX31855, screwless header, and capicator pre-soldered.
• Level shifter chip for converting 5V logic to 3.3V
• Two 3 pin 0.1" pitch male headers

No SMD soldering required, just solder on the headers and fire up the example code!

Tutorial

It is simple to get everything up and running.

1. Install a header or solder jumper wires to the pin connections
2. Connect a K-Type Thermocouple to the screw terminals
3. Wire the necessary connections to an Arduino or other microcontroller, the bare minimum connections ar +V, GND, SCK, SO, CS
4. If using an Arduino, load one of the samples from the MAX31855 Arduino Library and you should see temperature information in the serial console. With other microcontollers you can access the chip using a standard SPI interface. See MAX31855 for more details.
