Nano PCB Business Card Computer Kit with Arduino Nano + LED
Build a Wearable Business Card Computer: Arduino Nano Kit with OLED, RTC, and Sensors
Every part needed, pre-tested for compatibility, with an AI build companion trained on this exact project. Shipped from Bengaluru in 3-5 days.
Transform a credit-card-sized PCB into a fully functional wearable computer that displays time, temperature, and responds to button presses. Perfect for tech shows, hackathons, or as a unique badge, this kit places an Arduino Nano, OLED, precise RTC, and environmental sensor right on your lapel.
What You'll Build
A slim, battery-powered device with a 0.96-inch OLED screen that shows real-time clock, ambient temperature and humidity from the DHT22, and custom messages triggered by four tactile buttons. Wear it as a badge or slip it into a pocket – it’s a conversation starter and a proof of your embedded skills.
What You'll Learn
- Soldering surface-mount and through-hole components on a custom PCB layout
- Programming the Arduino Nano to interface I2C OLED, I2C RTC, and DHT22 sensor simultaneously
- Managing low-power battery operation with a LiPo cell and TP4056 charging circuit
- Designing portable, wearable enclosures and interactive button interfaces

Who This Kit Is For
Intermediate makers aged 15+ who want a portable electronics showcase. Ideal for CBSE Class 11-12 students building science fair projects, B.Tech ECE/EEE undergraduates at NITs, IITs or VIT needing a wearable demo, and ATL tinkering lab members participating in Smart India Hackathon.
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?
Scan the QR code to chat with your AI companion; it knows every part. For quick help, WhatsApp our support team.
Can I reprogram the Arduino Nano after assembling the kit?
Yes, the Nano’s USB port remains accessible. Upload your own code to customise the display, button actions, or sensor readings.
How long does the battery last on a single charge?
With the OLED on and sensor updates every 2 seconds, the 500mAh LiPo runs for about 4-5 hours. The TP4056 lets you recharge via micro USB.
Do I need prior soldering experience?
This intermediate kit assumes basic soldering skills. If you're new, our AI guide includes close-up photos and step-by-step instructions.
