## Description

## Overview

The LILYGO T-Embed CC1101 is a compact multi-protocol RF tool built around the ESP32-S3, combining a CC1101 sub-GHz transceiver with 13.56 MHz RFID capability and IR transmit/receive in a handheld T-Embed form factor. The CC1101 covers 300–348 MHz, 387–464 MHz, and 779–928 MHz bands, making it compatible with common garage door openers, car key fobs, weather stations, and industrial sensors.

The 1.9-inch IPS color display (ST7789V, 170×320) with rotary encoder navigation provides a complete interface for frequency analysis, signal capture, and replay. IR transmit and receive capabilities enable universal remote control applications and device emulation. RFID at 13.56 MHz supports reading and writing NFC and HF RFID cards.

WiFi and BLE from the ESP32-S3 enable network-connected applications and remote control. The T-Embed form factor is inspired by the Flipper Zero concept but leverages the ESP32 ecosystem, making it accessible to makers and security researchers for authorized RF testing and automation workflows.
