Easily one of UKSN’s favourite all-rounder nodes, the Heltec WiFi LoRa 32 V3 combines long-range LoRa radio, WiFi capabilities, and a compact development board all in one. Perfect for building portable, static, or experimental Meshtastic, LoRa, and off-grid comms projects.
 
Each node comes with a basic SMA antenna, so you can get started with signal testing or network expansion immediately.
 
Integrated LoRa & WiFi
Equipped with a 868MHz LoRa module and built-in Bluetooth & WiFi, the Heltec V3 allows for flexible wireless communications, local Meshtastic mesh networks, and cloud connectivity when needed.
 
OLED Display for Monitoring
A built-in 0.96” OLED screen provides real-time feedback such as signal strength, battery level, and device status — perfect for field deployments without needing a laptop or serial monitor.
 
Development Friendly
Based on ESP32, the Heltec V3 supports Arduino, MicroPython, and other development environments, making it suitable for members experimenting with custom LoRa apps, sensor nodes, and remote monitoring setups.
 
Budget Friendly Battery Options Available
As with most LoRa boards, the Heltec V3 does not include a battery. For members wanting a cheap, ready-to-go mobile node, we recommend pairing it with the UKSN 1100mAh Meshnology battery, which connects directly via JST 1.25 and powers your node reliably in the field.

💡 Why Buy Direct from UKSN?
When you buy from UKSN, each Heltec V3 unit is flashed with the latest version of Meshtastic before shipping. This means your node is ready to go straight out of the box, saving you time on setup and configuration. No need to worry about installing firmware or configuring your first mesh node - it’s all done for you. Buying direct also ensures:
 
Full UKSN support for setup and troubleshooting
Guaranteed compatibility with UKSN-recommended batteries and accessories
Confidence that your node is pre-tested and ready for deployment
