LILYGO T-HiGrow LoRa Shield 868/915MHz

Overview

The LILYGO T-HiGrow LoRa Shield is a LoRaWAN function expansion board designed to add long-range wireless connectivity to the T-HiGrow plant monitoring platform. The shield plugs into the T-HiGrow board and adds either 868MHz (European) or 915MHz (North American) LoRa radio capability, enabling sensor data to be transmitted to The Things Network (TTN) and visualized on platforms like Cayenne.

The shield includes two female pin headers for attachment and comes pre-configured for LoRaWAN uplink. Sample code demonstrates data transmission without power optimization, so custom implementations should add sleep modes for battery-powered deployments. The GitHub repository contains TTN integration examples and Cayenne dashboard configuration guides.
