Nano Distributed Ledger Node Kit with Arduino Nano + NRF24
Build a Hardware-Accelerated Distributed Ledger Node with Arduino Nano & NRF24
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 a network of low-cost sensor nodes that timestamp and cryptographically chain environmental readings, making data tampering mathematically impossible. This kit lets you build one such node: SHA256 hashing accelerated on the ATmega328P, NRF24 radio validating the chain across peers, and every block stored on board EEPROM.
What You'll Build
A working distributed ledger node that captures DHT22 temperature and humidity readings, timestamps them via DS3231 RTC, hashes the data with SHA256, and stores the chain in Arduino Nano EEPROM. Other nodes running identical firmware can verify block integrity over NRF24 wireless, demonstrating a practical mini-blockchain for sensor data provenance.
What You'll Learn
- Implement SHA256 hash chain logic on an 8-bit microcontroller with tight memory
- Interface NRF24L01 modules for reliable peer‑to‑peer packet communication
- Store timestamped sensor data blocks on EEPROM with chain validation
- Solder and assemble a multi‑component embedded system on a PCB prototype board

Who This Kit Is For
Ideal for final‑year B.Tech ECE or CS students prototyping a mini IoT blockchain for capstone or Smart India Hackathon projects, embedded systems researchers at IITs/NITs/VIT exploring secure sensor networks, and advanced hobbyists ready to move beyond blinking LEDs into distributed ledger design.
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?
The AI companion provides step-by-step debugging help, and you can reach our team on WhatsApp. We’ll walk you through the issue.
Does this kit include the complete source code?
The AI companion supplies a detailed explanation and example firmware for the SHA256 chain and NRF24 communication. You’ll write the core logic with guidance, making it a true learning experience.
Can I scale this to a multi‑node network?
Yes. The NRF24 radio supports point‑to‑multipoint; the firmware is designed with peer validation in mind. The companion can guide you on expanding to additional nodes.
Is this suitable for a final‑year engineering project?
Absolutely. The kit demonstrates a working tamper‑proof sensor chain, meets academic requirements for IoT security and blockchain, and builds practical soldering and debugging skills.
SHA256 hardware-accelerated chain of sensor readings stored on Nano EEPROM. NRF24 validates chain with peers.
