Lilygo T-Embed CC1101 Sub-GHz Transceiver Module with ESP32-S3 and TFT Display

Lilygo has recently launched the T-Embed CC1101, a transceiver module that integrates an ESP32-S3 dual-core LX7 microprocessor and a built-in Sub-GHz module based on the CC1101 chip, designed for communication in the 300-348 MHz, 387-464 MHz, and 779-928 MHz frequency bands. It features a 16MB flash memory, 8MB RSRAM, and supports wireless communication via Wi-Fi 802.11 b/g/n and BLE 5. The module is programmable through platforms like Arduino IDE and ESP-IDF and includes a 1.9-inch IPS colour TFT LCD with a 170×320 resolution powered by an ST7789V driver chip. Additionally, it has onboard functions like reset and boot buttons, IR transmit/receive capabilities, and battery voltage detection via IO04.

Previously we have covered some similar transceiver modules including the Miromico’s 2.4 Ghz Lora transceiver module, the LMD-401 Radio transceiver module, the Enocean Wireless transceiver module, and many more. Feel free to check those out if you are interested in this topic.
