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.
| Type | Encryption Method | Anti-Copy Capability | Attack Risk | Typical uses |
|---|---|---|---|---|
| Mifare Classic ✅ | Weak (CRYPTO1 algorithm, cracked) | Low | Easily cloned (e.g., via Proxmark3 tools) | Access control cards, public transportation cards (old system) |
| NTAG ✅ | No encryption (UID lockable) | Very Low | Data can be arbitrarily read | Smart labels, advertising interaction, and product anti-counterfeiting |
| Mifare Plus | AES-128 encryption | Medium-High | Requires physical access to crack | - |
| Felica | Dynamic encryption (SAM module) | High | Hard to crack (Japan-exclusive protocol) | Japanese transportation cards, electronic wallets |
| DESFire | AES/TDES encryption | Very High | Supports multi-app isolation, resists side-channel attacks | High-security access control, campus one-card, electronic passport |
| CPU Card | Hardware encryption (SM4/ECC/RSA) | Very High | Supports China's national cryptographic standards, financial-grade security | Bank card, ID card, social security card |
🟢 PlatformIO is recommended because these examples were developed on it. 🟢
- Install Visual Studio Code and Python, and clone or download the project;
- Search for the
PlatformIOplugin in theVisualStudioCodeextension 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.iniconfiguration file, uncomment inexampleto select a routine, and then pressctrl+sto save the.iniconfiguration 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;
-
Install Arduino IDE
-
Copy all files under
this project/lib/and paste them into the Arduion library path (generallyC:\Users\YourName\Documents\Arduino\libraries); -
Open the Arduion IDE and click
File->Openin the upper left corner to open an example inthis project/example/xxx/xxx.inounder this item; -
Then configure Arduion. After the configuration is completed in the following way, you can click the button in the upper left corner of Arduion to compile and download;

Sleep power consumption.
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;
