## Description

## Overview

The LILYGO T-HaLow P4 is a high-performance development board pairing the powerful Espressif ESP32-P4 application processor with an onboard ESP32-C6 module for WiFi HaLow (IEEE 802.11ah) connectivity. The ESP32-P4 features a dual-core RISC-V processor capable of H.264 1080P 30FPS video encoding/decoding with MIPI-CSI camera input and MIPI-DSI display output, 16MB flash, and 8MB PSRAM. WiFi HaLow operates in the sub-1GHz band (900MHz), offering up to 1km+ range with lower power consumption than standard WiFi — ideal for outdoor IoT deployments, smart agriculture, and building automation where standard WiFi falls short. The ESP32-C6 also provides BLE 5 and 802.15.4 for Thread/Zigbee. Development is supported via Arduino IDE, VS Code, and ESP-IDF.
