Why Choose This?
- Genuine & Reliable: Unlike cheap clones with inconsistent quality, the NanoPi R2S uses an authentic ATmega328P with stable voltage regulation, ensuring your projects run without unexpected resets or failures.
- Ultra-Compact Design: At just 45 x 18 mm, this board fits into enclosures and wearable housings where standard Arduino boards simply cannot, giving you 14 digital pins and 8 analog inputs in a remarkably small footprint.
- Bengaluru-Based Support: Get fast domestic shipping, hassle-free warranty claims, and responsive technical support from The Engineer Store - no waiting weeks for overseas replacements.
Project Ideas
- Compact Weather Station: Use the 8 analog pins to connect temperature, humidity, and barometric pressure sensors, then log data to an SD card or transmit wirelessly via an ESP module.
- Wearable LED Controller: Leverage the 6 PWM outputs to drive addressable LED strips for costumes, bike lights, or wearable art installations - the tiny form factor makes it easy to embed into fabric or 3D-printed housings.
- Automated Plant Watering System: Read soil moisture levels through the analog inputs and control water pumps via digital pins, creating a fully autonomous irrigation system for your balcony garden.
What's in the Box
- 1 x NanoPi R2S Board (ATmega328P)
- 1 x Header pin set (unsoldered)
Frequently Asked Questions
Is the NanoPi R2S compatible with the Arduino IDE?
Yes. The ATmega328P is fully supported by the Arduino IDE. You can program it using a USB-to-serial adapter and select the appropriate board profile in the IDE settings.
Do I need a separate programmer to upload code?
You will need a USB-to-serial (FTDI) adapter since the board does not include an onboard USB interface. These adapters are available separately at The Engineer Store.
Can I power this board with a 3.7V LiPo battery?
The ATmega328P can operate at lower voltages, but for stable 5V operation and reliable analog readings, a boost converter or regulated 5V supply is recommended.
How many sensors can I connect simultaneously?
With 8 analog pins and 14 digital pins, you can connect multiple sensors at once. For additional expansion, use I2C or SPI peripherals to extend your I/O capabilities significantly.
Is 30 KB of flash memory enough for complex projects?
30 KB handles most embedded applications comfortably, including sensor reading, motor control, and basic communication protocols. For memory-intensive tasks like image processing, consider a more powerful board.
What warranty and return policy applies?
The Engineer Store offers a standard warranty on this product. If you receive a defective unit, contact our Bengaluru support team for a quick replacement or refund - no international shipping hassles.
