T-Embed CC1101 Sub-GHz Radio Board
Build your own sub-GHz signal analyzer, NFC reader, or Flipper Zero alternative with one board. The T-Embed pairs an ESP32-S3 with a CC1101 radio (300-928 MHz), PN532 NFC module, and a 1.9" color LCD in a compact, programmable package. Flash custom firmware, sniff frequencies, read NFC tags, and display it all on the built-in screen.
Project idea: Build a portable sub-GHz spectrum scanner that logs signal activity to an SD card and displays a waterfall plot on the LCD.
Key Features
- Sub-GHz radio (CC1101, 300-928 MHz): analyze signals, replay remotes, build custom RF tools
- NFC read/write via PN532: clone badges, trigger automations, read NDEF tags
- 1.9" color LCD built in: no wiring a separate display for your UI
- ESP32-S3 core with WiFi + Bluetooth: OTA updates and wireless data logging
- USB-C for power and programming: flash via Arduino IDE, PlatformIO, or ESP-IDF
- Open-source firmware community: multiple GitHub projects already support this board
- Compact form factor with onboard antenna: pocketable and field-ready
Frequently Asked Questions
Is the T-Embed CC1101 compatible with Flipper Zero firmware?
Not directly. Flipper runs its own OS on different hardware. But several open-source projects (like Bruce firmware) bring similar sub-GHz and NFC functionality to ESP32-S3 boards with CC1101 radios. You get comparable features with more flexibility to customize.
What frequency ranges does the CC1101 radio cover?
The CC1101 operates across 300-348 MHz, 387-464 MHz, and 779-928 MHz bands. This covers common sub-GHz frequencies used by garage doors, weather stations, tire pressure sensors, and many IoT devices. It does not cover 2.4 GHz (that is handled by the ESP32-S3's built-in WiFi/BT radio).
