HC-12 Long Range Serial Link Kit with Arduino Nano + LED
HC‑12 Arduino Nano Kit: Wireless Serial Communication Up to 600 Metres – No LoRa Required
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 two Arduino Nanos chatting wirelessly across a school campus, a farm field, or even your home – no internet, no Bluetooth, just a solid 600‑metre radio link. This kit gives you exactly that: a pre‑tested pair of HC‑12 433MHz transceivers that turn any serial data into a long‑range wireless pipeline. Build a remote weather station, a wireless alarm, or a simple text messenger – all with plug‑and‑play simplicity, just like a wired UART connection.
What You'll Build
Two battery‑powered nodes that exchange serial data over distances up to 600 metres. The transmitter node can send sensor readings or typed messages; the receiver node instantly displays the incoming data on the included 0.96‑inch OLED, giving you a real‑time view of your wireless link.
What You'll Learn
- Configure the HC‑12 module’s serial parameters (baud rate, channel, power level) via AT commands.
- Transmit and receive serial data wirelessly using Arduino’s SoftwareSerial library.
- Interface an I2C OLED display to show received messages and signal strength.
- Build battery‑powered, standalone wireless nodes with voltage regulation and minimal power consumption.

Who This Kit Is For
This kit is ideal for CBSE Class 11‑12 students building physics practicals, B.Tech ECE/EEE students prototyping wireless communication projects, and ATL Tinkering Lab participants exploring radio frequency data transfer. It’s also a favourite among Smart India Hackathon teams who need a reliable point‑to‑point serial link without the overhead of LoRaWAN or WiFi.
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 by scanning the QR code on the box; it will guide you step by step. You can also reach us directly on WhatsApp for a human touch.
Can I increase the range beyond 600m?
Yes. In open rural areas, the HC‑12 can reach up to 1 km with higher baud rates and external directional antennas. For typical urban use, the included whip antennas reliably give you 500‑600 metres.
Does this kit include a programming cable?
The Arduino Nanos require a mini‑USB cable for programming, which is not in the box. Most Indian households already have one from old cameras or power banks; if not, you can add it while checking out.
Can I use this kit to send sensor data from a remote field?
Absolutely. The receiver node can display sensor readings on the OLED or pass them to a computer via USB. Many students use this as the base for an agricultural IoT project or remote weather station.
HC-12 433MHz transceiver sends serial data between two Arduinos over 600m range without LoRa complexity.
