LILYGO T-Embed CC1101: Enabling Sub-GHz and NFC/RFID Communication
LILYGO launched the T-Embed CC1101, built around the ESP32-S3 Dual-core LX7. It supports Wi-Fi, BLE 5, and Sub-GHz wireless communication, targeting remote and low-power IoT projects.
The ESP32-S3 microcontroller is paired with 16MB of Flash memory and 8MB of PSRAM. The CC1101 chip operates across frequency bands of 300-348 MHz, 387-464 MHz, and 779-928 MHz, with a communication range of up to 50 meters.
An integrated radio antenna ensures efficient long-range communication, and the board also supports external radio modules for additional Sub-GHz applications.
The board features a 1.9-inch ST7789V IPS color TFT LCD with a resolution of 320 x 170 pixels, interfaced via SPI with the ST7789V driver chip.
Additionally, the board is equipped with an infrared transmitter and receiver, a built-in microphone, and a PN532 NFC/RFID transceiver for contactless communication at 13.56 MHz.
For further I/O expansion, the device includes two Qwiic connectors, an encoder for navigating the device menu, and a MicroSD card slot for additional storage.
