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.
The Sub-GHz application supports external radio modules based on the CC1101 transceiver.
The PN532 only supports high-frequency cards at 13.56MHz, does not support low-frequency cards at 125K, does not support CPU cards, and does not support encryption cards.
"✅" represents a card of support.

PlatformIO is recommended because these examples were developed on it.
PlatformIO
Search for the PlatformIO plugin in the VisualStudioCode extension and install it;
After the installation is complete, you need to restart VisualStudioCode
After opening this project, PlatformIO will automatically download the required tripartite libraries and dependencies, the first time this process is relatively long, please wait patiently;
After all the dependencies are installed, you can open the platformio.ini configuration file, uncomment in example to select a routine, and then press ctrl+s to save the .ini configuration file;
Click ☑️ under VScode to compile the project, then plug in USB and select COM under VScode;
Finally, click the ➡️ button to download the program to Flash;
Unable to detect 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;
