6. ઓપરેટિંગ સૂચનાઓ

The M5Stack Core2 is designed for flexible operation depending on your application. Here are general guidelines:

• Touch Screen Interaction: Navigate menus and interact with applications using the 2-inch capacitive touch screen.
• વર્ચ્યુઅલ બટનો: The three virtual buttons below the screen can be programmed for various functions within your applications.
• ભૌતિક બટનો: The physical RST (Reset) button can be used to restart the device. The power button can be used for power cycling.
• બાહ્ય મોડ્યુલો: Connect compatible M5Stack modules and sensors to the GROVE port to expand functionality. Ensure proper connection and power supply for external modules.
• SD કાર્ડનો ઉપયોગ: Insert a microSD card into the designated slot for additional storage. Ensure the card is formatted correctly (e.g., FAT32).

7. જાળવણી

Proper maintenance ensures the longevity and optimal performance of your M5Stack Core2:

• સફાઈ: ઉપકરણને સાફ કરવા માટે નરમ, સૂકા કપડાનો ઉપયોગ કરો. પ્રવાહી ક્લીનર્સ અથવા ઘર્ષક સામગ્રીનો ઉપયોગ કરવાનું ટાળો.
• સંગ્રહ: ઉપકરણને સીધા સૂર્યપ્રકાશ અને અતિશય તાપમાનથી દૂર ઠંડી, સૂકી જગ્યાએ સંગ્રહિત કરો.
• બેટરી સંભાળ: Avoid fully discharging the battery frequently. If storing for extended periods, charge the battery to about 50-70% to preserve its lifespan.
• ફર્મવેર અપડેટ્સ: Regularly check the official M5Stack webતમારા ઉપકરણમાં નવીનતમ સુવિધાઓ અને બગ ફિક્સેસ છે તેની ખાતરી કરવા માટે ફર્મવેર અપડેટ્સ માટેની સાઇટ.
• શારીરિક સુરક્ષા: While durable, avoid dropping the device or exposing it to excessive force or moisture.

8. મુશ્કેલીનિવારણ

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.
