One of the first IoT projects that I worked on, and the one that is probably still my favorite is my dual probe thermocouple BBQ temperature monitor. I’ve built quite a number of prototypes, and I keep promising a tutorial on how to make one. I decided to build my own MAX31855 breakout designed just for the Imp, and especially the C3V0, and P3V3 boards. There are other MAX31855 breakouts available, but this one contains only the hardware recommended by Maxim Integrated and an Omega thermocouple jack. It is not 5V compliant. If you are interested in purchasing one of the rev 1 boards, please email email@example.com as I will have a few of them available. The board will be regularly available from MakeDeck in a few weeks. Please post comments and suggestions.
The board is shown here being read by C3V0, and flanked by Aria and P3V3.
