| GPS and Location | LILYGO T-Beam Supreme | The T-Beam Supreme has a built-in L76K GPS module for location sharing on the mesh network. The Heltec V3 has no GPS — you would need to add an external module. For hiking, tracking, and outdoor use, the T-Beam's GPS is essential. |
| Battery and Power | LILYGO T-Beam Supreme | The T-Beam holds a standard 18650 battery (2600-3500mAh, easily swappable) plus solar panel input for permanent outdoor deployment. The Heltec V3 uses small LiPo packs (typically 500-1000mAh). For multi-day field use, the T-Beam's battery system is superior. |
| Size and Portability | Heltec WiFi LoRa 32 V3 | The Heltec V3 is 50mm long vs the T-Beam's 100mm. Half the size makes the Heltec easier to mount in enclosures, carry in a pocket, or hide in a deployment. The T-Beam's length comes from the 18650 battery holder. |
| Cost | Heltec WiFi LoRa 32 V3 | The Heltec V3 costs roughly half the T-Beam Supreme. For building a mesh network with multiple nodes, the Heltec's lower cost means more nodes for the same budget — and more nodes means better mesh coverage. |
| LoRa Range | LILYGO T-Beam Supreme | Both use the SX1262 radio, but the T-Beam achieves slightly better range (up to 15km vs 10km) due to better antenna design and ground plane. In practice, real-world range depends more on antenna choice and terrain than board design. |
