V. Cautions
1. When the TH0 interface doesn't use PT1000, you can't insert the jump cap on
it, otherwise 100K NTC won't be used as normal.
2. When using CAN communication, you need to see whether it is used as a
terminal. If it is, you must insert the jumper cap on the 120R position.
3. When DIY crimping, you need to pay attention to the line sequences, and do
DIY according to the Pin diagram so as to avoid the power line from being
reversely connected or connected to the CAN signal, which will get the module
burned.
4. If there's no external power supply during writing firmware via USB port, you
need to short the VUSB by jumper cap so as to supply the module with working
voltage.
5. The load current of the heating rod and the fan interfaces shall not exceed the
maximum withstand current to prevent the MOS tube from being burned out.
VI. FAQ
Q: What's the maximum current for the heating rod and fan interface?
A: The maximum output current of the heating rod port: 5A.
The maximum output current of the fan interface: 1A, peak value 1.5A.
The total current for the heating rod, stepper driver and fans needs to be less than
9A.
Q: Cannot update firmware via USB port?
A: You need to make sure that the jump cap is inserted on VUSB, and the
indicator light on the board is on.
