| Category | Winner | Why |
|---|---|---|
| Battery Life and Sleep Current | RAK WisBlock Meshtastic Starter Kit | The RAK WisBlock achieves 2uA deep sleep current — orders of magnitude lower than the Heltec V3 (~20mA with display) and T-Beam (~10mA with GPS). A 3000mAh battery lasts months on the RAK in router/client mode. For permanent outdoor relay nodes, the RAK's power efficiency is unmatched in the Meshtastic ecosystem. |
| All-in-One Mobile Readiness | LILYGO T-Beam Supreme | The T-Beam Supreme includes GPS (L76K), 18650 battery holder, solar charging input, LoRa (SX1262), and WiFi/BLE in a single board. No soldering, no external modules, no assembly. The RAK requires stacking modules. The Heltec has no GPS or battery holder. For grab-and-go field use, the T-Beam is ready out of the box. |
| Modularity and Customization | RAK WisBlock Meshtastic Starter Kit | RAK's WisBlock system uses snap-in modules on a baseboard — swap GPS modules, add environment sensors, change LoRa modules, attach solar panels. Over 50 WisBlock modules are available. The T-Beam and Heltec are fixed-design boards with no modular expansion system. |
| Cost Per Node | Heltec WiFi LoRa 32 V3 | The Heltec V3 costs roughly half the T-Beam Supreme and less than a full RAK WisBlock stack. For building mesh infrastructure with many relay nodes, cost per node determines how many nodes you can deploy — and more nodes means better mesh coverage and reliability. |
| LoRa Range | LILYGO T-Beam Supreme | The T-Beam achieves up to 15km theoretical range versus 10km for the Heltec and RAK. All three use the SX1262 transceiver, but the T-Beam's larger PCB provides a better ground plane for the antenna. In practice, antenna choice and mounting height matter more than board design. |
| Display and User Interface | Heltec WiFi LoRa 32 V3 | The Heltec V3 has a built-in 0.96-inch OLED display showing mesh status, messages, and signal strength. The T-Beam Supreme also has a display. The RAK WisBlock base board has no display — you need the optional OLED module. For monitoring node status at a glance, the Heltec and T-Beam have the edge. |
