Troubleshooting

Frequently Asked Questions

• 1. How do I power the K210 module?
     Answer: The K210 module requires a 5V power supply. You can power it through the microUSB port on the side or through an external serial port.
• 2. Can the K210 module run programs without a TF card? Are there any restrictions on TF cards?
     Answer: Yes, programs can run. Because the K210 has limited onboard storage, the TF card is mainly used to store model files. If you are not performing AI recognition, a TF card is not required. Without a TF card, program files are saved to the K210's Flash chip. The TF card must be formatted as FAT32. Some TF cards on the market are incompatible; please verify with actual testing.
• 3. Why can't the K210 connect to the CanMV IDE when plugged in via USB?
     Answer: Confirm that the selected port number matches the K210 module's port. When connecting, check Advanced and select Mode-2. If other firmware has been flashed to the K210 module, re-flash the factory firmware before connecting again.
• 4. How large is the front screen? Is it resistive or capacitive?
     Answer: The screen built into the K210 module is a capacitive touchscreen. It is 2.0 inches with a resolution of 320×240.
• 5. Why doesn't the program run after connecting the K210 to a computer via microUSB and opening a serial terminal?
     Answer: When connecting the K210 module to a serial terminal, you need to configure RTS and DTR. If you are using the UartAssist serial terminal, after opening the serial port the K210 module will not run the program immediately. You must first click 7.RTS, then click 4.DTR before the program runs normally. (The red status must turn black before it works properly.)
