Sample Arduino 1.0 *.ino to read °C from MAX31850 1-wire chip

ReflowController *.ino for Arduino Nano Shield V9 Support for MAX6675,MAX31850 and MAX31850

Created new Arduino Nano Shield Version 9
Arduino Nano Shield which supporting all current Maxim Thermocouple Chips
– MAX31850 1-wire
– MAX6675 I2C
– MAX31855 I2C
PCB is prepaired also for following option:
– DS1307Z Realtime Clock
– 1-Wire devices (ex. DS18S20,../blog../blog)
– 3.3V voltage regulator LM1117MPX-3.3V
– 5V oder 12V voltage regulatorr LM2937IMP oder LM340
– Relais G5V1 5V oder 12V
You can connect a 2×16 LCD Display:
– HD44780 LCD 2X16

Don’t care if they need 3.3V or 5V or if thermocouple has to be
grounded, everything is implemented to get them running with
different assembly options

If you are scared about soldering the MAX31850.
It’s really simple if you do it in the following way:

1. Clean the PCB
2. Put some solder on the MAX31850 pads, there should be some
smale solder balls on the pads
3. Place carefully the MAX31850 on the PCB, take care align it
correctly to the solder pads on the PCB
4. Take an air rework station to fix it on the PCB, the solder has only
to fix the chip. It will be soldered in the next step
5. Put a little flux paste beside the MAX31850 chip
6. Solder it with a soldering iron on the PCB
7. You can see that it’s good soldered when solder is covering the
hole pad on the PCB

I have some PCB’s left if you like to test:

You can get them in my shop:

I will add some example Arduino code later –> DS1307Z, MAX6675, MAX31850, MAX31855
