1. Introducció
The LILYGO T-Display S3 Pro LR1121 is an advanced development board built upon the T-Display S3 Pro External Expansion Module. It integrates the LR1121 chip, offering dual LoRa band capabilities (Sub-G band and 2.4G band). This board features a 2.33-inch touch IPS TFT SPI LCD for interactive applications.
Key integrated functions include motor vibration, Real-Time Clock (RTC), speaker, and microphone. It is powered by a built-in high-capacity 2000mAh Li-ion battery. The robust ABS+PC material shell is designed with two external LoRa antenna ports, ensuring optimal wireless performance without internal interference. A 1/4-inch screw mount at the bottom allows for attachment to outdoor fixtures like tripods.
