🚀 What is it?

The LILYGO T3S3 V1.2 is a professional-grade LoRa development kit combining the powerful ESP32-S3 dual-core processor with the high-efficiency SX1262 radio chip.

This is a complete, curated bundle specifically optimized for the 915MHz frequency. Unlike buying bare boards, this kit includes every essential component to get you on the air immediately:

1x T3S3 V1.2 Main Board (ESP32-S3 + SX1262 LoRa)

1x 915MHz High-Gain Antenna (Tuned for maximum range)

1x JST 1.25mm Battery Cable (For portable/solar setups)

2x Header Pins (Ready for your custom sensors)

🛠️ Why did you make it?

Building a Meshtastic node or an off-grid IoT sensor shouldn't be a struggle of hunting for compatible cables or waiting weeks for a specific antenna.

I created this all-in-one starter kit to eliminate the guesswork. I wanted to provide a true plug-and-play experience for the global mesh community, ensuring that anyone—from beginners to pro-developers—can deploy a reliable 915MHz node without the headache of missing parts.

✨ What makes it special?

This kit stands out from generic LoRa boards through its focus on reliability and performance:

Next-Gen SX1262: Significant upgrades over older SX1276 models, offering better power efficiency and a powerful +22dBm transmit capability.

ESP32-S3 Power: Future-proof hardware with dual-core processing, 8MB PSRAM, and native support for Bluetooth LE 5.0.

Hand-Tested: Each kit undergoes a manual power-on test and physical inspection before shipping to ensure your project starts without a hitch.

Note: This kit is set for 915MHz, the legal standard for North America (US/CA) and Australia.
