LILYGO® T3S3 ESP32-S3 LoRa Development Board - SX1262/SX1276/SX1280 2.4GHz, WiFi Bluetooth Module, 0.96 OLED, Type-C

Introduction

The T3S3 is the latest iteration in the LoRa series, featuring the SX1280 LoRa module. This module supports the 2.4GHz frequency band and can be used globally. It is powered by the ESP32 main control chip and supports TF cards for additional storage.

Important: When using the SX1280 PA module, it is recommended to control the output power of the SX1280 chip between 2-5 dBm to ensure that the module outputs a power of 20 dBm. Exceeding 5 dBm may damage the FEM chip. Setting the output power to 3 dBm is optimal for maintaining an output power of 20 dBm.
