+### About SD Card：
+We were able to successfully test SD with SanDisk no larger than 32GB; But some other cards don't, and it's not clear why;
+
+Therefore, when the SD card is not detected, it is recommended to change a SanDisk card not larger than 32G;

 ### Wireless transceiver：
 
 T-Embed-CC1101 has a built-in Sub-GHz module based on a `CC1101` transceiver and a radio antenna (the maximum range is 50 meters). Both the CC1101 chip and the antenna are designed to operate at frequencies in the 300-348 MHz, 387-464 MHz, and 779-928 MHz bands.
