The Heltec V4 is the latest generation of one of the most popular Meshtastic boards - now with higher transmit power, better memory, and proper plug-and-play GPS support. Unlike the V3, the GPS module connects directly via the onboard port with no soldering required, making this an ideal choice for members who want location tracking without custom wiring. This is a powerful, compact, ready-to-deploy node for portable, vehicle, or fixed mesh builds.

Why Choose the Heltec V4 Over the V3?
The V4 removes one of the biggest pain points of the V3: GPS installation. No soldering. No tiny pads. Just plug it in and go. It can also handle solar charging directly without needing an additional charge controller, making it far easier to build long-term off-grid nodes. Combined with higher transmit power and increased memory, the V4 is a more capable and future-proof platform for reliable UKSN Project LoRa mesh deployments.
