LoRa Mesh Relay Network
LoRa Mesh Relay Network Kit — Build Multi-Hop Communication with Live Hop Counts
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Imagine sending a sensor reading from the far corner of your farm to a gateway over a kilometre away — with no cellular network and no Wi‑Fi. This kit turns that scenario into a hands‑on project. You’ll assemble three LoRa nodes that automatically relay messages to extend coverage far beyond a single direct link, while an OLED screen shows how many hops each message took to arrive.
What You'll Build
Three standalone LoRa communicators that form a self‑healing mesh. Node A transmits a message; Node B receives it and intelligently passes it to Node C, even if C is out of range of A. The OLED on each node displays the hop count, so you can actually see the relay in action. Use it to monitor remote sensors, create a disaster‑response drill, or add long‑range wireless to a Smart India Hackathon prototype.
What You'll Learn
- LoRa physical layer setup at 433 MHz and antenna matching
- Mesh networking logic — node addressing, routing table, and TTL
- OLED integration to display live hop‑count data
- Soldering and power management for portable Li‑Ion nodes

Who This Kit Is For
Built for intermediate makers who’ve tried basic Arduino and are ready to tackle real embedded communication. Ideal for CBSE Class 11‑12 students exploring networking, B.Tech ECE/EEE projects on rural connectivity, Smart India Hackathon teams prototyping long‑range sensor grids, and ATL Tinkering Lab champions pushing beyond line‑of‑sight radio.
Built and Backed by Compoden
Every Compoden kit ships with an AI build companion trained on this exact project — accessible via a QR code on the box, with WhatsApp and email backup. We've spent 10 years building projects for makers, schools, and institutions across India. If a part fails because of a manufacturing defect, replace it free within 7 days.
What if I get stuck during the build?
Open the AI companion from the QR code; it understands every component and can step you through the code and wiring. If you need human help, WhatsApp us and we’ll reply within hours.
Can I scale this mesh beyond three nodes?
Yes. The mesh logic is written to handle multiple relays — just add identical node modules and assign unique addresses. The hop‑count display adapts automatically.
What range can I expect with multiple hops?
Each direct link works reliably up to 1km in open air. With two relay nodes, you can bridge over 2km. Actual range depends on terrain; including a clear line of sight gives the best results.
Is this kit allowed as a project for Smart India Hackathon or college evaluations?
Absolutely. The mesh relay network demonstrates practical communication protocols, low‑power design, and IoT principles — all highly relevant for hackathon jury panels and engineering vivas.
Three LoRa nodes relay messages to extend range beyond direct 1km link. OLED shows hop count per message.
