Overview
The LILYGO Helium T-Beam is a specialized variant of the T-Beam development board designed for deployment on the Helium decentralized LoRaWAN IoT network. Built around the ESP32 dual-core SoC with 4MB flash and 8MB PSRAM, it combines a Semtech SX1276 LoRa radio (868MHz or 915MHz) with a u-blox NEO-6M GPS module featuring RTC crystal and interrupt/wakeup support for low-power positioning. The AXP2101 power management unit handles efficient power regulation and 18650 lithium battery charging via USB. Three hardware buttons (Power, IO38, Reset) allow user interaction. The board is ideal for building Helium network coverage mappers, LoRaWAN sensor nodes, and GPS asset trackers that earn HNT tokens by providing network coverage.
Use Cases
4LoRa Mesh Networking
Building off-grid mesh communication networks using LoRa radio for text messaging, location sharing, and sensor data relay without cellular or internet infrastructure.
GPS Tracking
Location tracking and navigation using GNSS satellite receivers.
IoT Gateway
Acting as a local IoT gateway that aggregates data from sensors, runs MQTT broker, Node-RED, or Home Assistant, and bridges to the cloud.
Asset Tracking
Tracking the location and status of physical assets like vehicles, packages, and equipment.
