16.DC 5V output maximum current: 1A

Precautions

1. When the PT1000 is not used for the TH0 interface, the jumper cap cannot be inserted on it, otherwise the 100K NTC cannot be used normally

2. When using CAN communication, you need to see if it is used as a terminal. If it is a terminal, you must plug the jumper cap at the 120R position;

3. When DIY crimping, you need to pay attention to the line sequence, and do DIY according to the Pin diagram to avoid the power line being reversed or connected to the CAN signal, which will cause the module to burn;

4. When programming the program through the USB port, if there is no external power supply, you need to short the VUSB jumper cap to provide the module with working voltage;

5. The load current of the heating rod and the fan interface should not be greater than the maximum withstand current to prevent the MOS tube from being burned out.
