8. ការដោះស្រាយបញ្ហា

This section addresses common issues you might encounter with your M5Stack Core2.

Q1: What is the maximum supported capacity of the SD card, and why is there no response when the SD card is inserted?

Theoretically, devices based on ESP32 support up to 16GB. We recommend using a SD card model SDSQUNC-016G-ZN6MA. Ensure the SD card is properly inserted and formatted.

Q2: Using the battery in either of the battery ports on the USB unit or the Core2 forces the unit to stay powered on continuously. Any attempt to shut down using the side button causes the device to restart after.

We have found that the reason is that the filter capacitor capacity of the USB 1.2 module is too large. If you still need to use batteries to power the Core2 + USB 1.2 solution, to avoid frequent restarts, the following two solutions can be adopted:

• Remove the filter capacitor.
• Replace it with a smaller capacity filter capacitor (10uF is recommended).

Q3: How to extend the Core2 with an extension module?

You must remove the original bottom and battery of the Core2, then you can stack another module extension.
