ESP32 DTN Router Kit: Simulate Deep Space Communication with Store-Carry-Forward Networks

Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.

When a direct path to the destination doesn’t exist — like a rover on Mars communicating with Earth — data must be stored, carried, and forwarded until a link becomes available. This kit lets you build three ESP32-based nodes that implement the DTN bundle protocol over LoRa, creating a working model of the interplanetary internet. You’ll write the logic that decides when to hold a bundle in flash, when to forward it to a newly discovered neighbour, and how to expire messages that have outlived their time-to-live.

What You'll Build

Three fully independent router nodes, each with an ESP32, LoRa transceiver, RTC, microSD storage, and OLED display. The nodes continuously scan for peers; when a link is established, they exchange bundles stored in non‑volatile memory. The OLED shows node ID, number of buffered bundles, neighbour status, and system uptime in real time. By moving nodes in and out of range, you can demonstrate the core store‑carry‑forward behaviour that defines delay‑tolerant networks.

What You'll Learn

• Implement store‑carry‑forward routing with bundle priority and TTL handling
• Configure LoRa mesh addressing and adaptive data rate for variable link quality
• Manage microSD‑based persistent storage for bundles that survive node restarts
• Synchronize DS3231 real‑time clocks across nodes to enforce accurate message expiry

Why Buy This Kit Instead of Sourcing Parts Separately

Who This Kit Is For

This advanced kit is designed for B.Tech ECE, EEE, and Telecommunications students working on final‑year networking or satellite communication projects. It fits the hardware track of Smart India Hackathon, deep‑tech explorations at IIT/NIT/VIT/BITS, and serious hobbyists who want to move beyond simple sensor networks into protocol design. A solid understanding of C/C++ and Arduino IDE is assumed.

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.
