1. The power supply part uses the step-down chip TD1509P5, and the input voltage can reach up to 45V.

2. Use the SPI communication of STM32F030F4P6 to capture the temperature values ​​of the two MAX31855s based on the CS chip select.

3.MAX31855 itself does not have anti-interference capability, and the hardware anti-interference circuit design verification

4. The circuit part is designed with a 485 interface to facilitate the computer to view the obtained temperature value.

5. Comes with a dip switch to set the station number for subsequent expansion of MODBUS communication.

6. Reserve the download interface of XH-4 to facilitate subsequent debugging and downloading

7. The appearance design is based on a standard shell on Taobao. You can directly insert it into the shell if there is no problem later.

Note: The data changes in the serial port assistant are caused by touching the thermocouple with your hand.
