LILYGO T-Halow

📦 Project Versions

T-Halow has two different versions, primarily distinguished by their pairing methods. Please select the corresponding documentation based on the hardware version you have:

Note: Both versions of T-Halow use the same AT Command Set.

Regarding the SDK for the TX-AH module, Taixin does not currently provide detailed API documentation. If you need to compile it yourself, you can refer to this project: hgSDK

🚀 Product Overview

LILYGO T-Halow is a versatile IoT development board integrating ESP32-S3 as the main controller, Wi-Fi HaLow (802.11ah) for long-range communication, a 2MP/5MP camera, and an RJ45 Ethernet port. It is specifically designed for scenarios requiring long-distance, low-power, and highly reliable image transmission and wireless communication, suitable for applications such as security monitoring, remote inspection, and environmental monitoring.

Core Features

• ✅ Dual-Band Long-Range Communication: Supports 2.4GHz Wi-Fi + Bluetooth 5 (LE) and Wi-Fi HaLow (730-928MHz)
• ✅ High-Definition Camera Capability: Supports OV2640 / OV5640 cameras, up to 5 megapixels
• ✅ Wired Network Backup: Built-in RJ45 Ethernet port, supports enabling network functions with replaceable firmware
• ✅ Large Capacity Storage: 16MB Flash + 8MB PSRAM, supports TF card expansion
• ✅ Outdoor Power Solution: Supports 18650 battery power supply, integrated battery ADC monitoring

📡 Wi-Fi HaLow Introduction

Wi-Fi HaLow (802.11ah) is a long-range, low-power Wi-Fi standard optimized for IoT. With the same transmit power, it offers longer transmission distances and better wall penetration capabilities compared to traditional 2.4GHz/5GHz Wi-Fi.

T-Halow is equipped with Taixin's TX-AH module, supporting:

• Operating Frequency Band: 730–950MHz
• Channel Bandwidth: Adjustable 1/2/4/8MHz
• Physical Throughput: 150Kbps – 32.5Mbps
• Transmission Distance: Up to several kilometers (depending on environment)

📊 TX-AH Model Comparison

Remarks:

1. Differences between the P series modules and the earlier A series modules:
   • (1) P series lower left silkscreen starts with P, A series starts with R
   • (2) P series PIN4/5 require power supply, A series does not
2. Modules default without shield; versions with shield have -S suffix added to the module name (S stands for Shield)

🚀 Quick Start

🟢 It is recommended to use PlatformIO, as these examples were developed on PlatformIO. 🟢

PlatformIO Development Environment

1. Install Visual Studio Code and Python. Clone or download this project.
2. Search for and install the PlatformIO extension in VSCode extensions.
3. Restart VSCode after installation.
4. Open this project. PlatformIO will automatically download required third-party libraries and dependencies. The first-time process may take a while; please be patient.
5. After all dependencies are installed, open the platformio.ini configuration file, uncomment the example program in example, then press Ctrl+S to save.
6. Click the ☑️ at the bottom of VSCode to compile the project, insert the USB cable, and select the COM port in VSCode.
7. Finally, click the ➡️ button to upload the program to Flash.

Arduino IDE Development Environment

1. Install Arduino IDE

2. Copy and paste all files from T-Halow/lib/ into the Arduino library path (typically C:\Users\Username\Documents\Arduino\libraries).

3. Open Arduino IDE, click File -> Open in the top left, and open the example under T-Halow/example/xxx/xxx.ino.

4. Configure Arduino as follows. Once done, you can click the button in the top left of Arduino to compile and upload:

🧭 Application Scenarios
