Arduino Nano R3 Development Board

Arduino Nano R3 Development Board (CH340)
If you're tired of bulky boards and messy jumper wires, the Nano R3 is a lifesaver. It’s designed to plug straight into a breadboard, making it incredibly fast to prototype your ideas.

 
Small Size, Big Features:
• Breadboard Ready: At only 43 mm x 18 mm, it’s tiny enough for wearables or small robotics. Since the pins are spaced perfectly for a breadboard, you can just pop it in and start building.
• The Same "Brain": It runs at 16 MHz with 32 KB of flash memory. You get 14 digital I/O pins (6 with PWM) and actually 8 analog inputs—that’s two more than the standard Uno!
• Budget-Friendly USB: This version uses the CH340 chip for programming. It keeps the cost low while staying totally reliable for coding and serial communication.

 
Powering Your Project:
• Flexible Input: You can power it through the Mini USB port, a regulated 5V pin, or even an unregulated battery (6V–20V). It’s smart enough to switch between power sources automatically.
• Streamlined Design: To save space, it ditches the bulky DC power jack, making the whole board much lower profile for tight enclosures.

 
Best For:
This is the go-to board for IoT prototypes, embedded systems, and any project where every millimeter counts. If you’ve finished prototyping on an Uno and want to move to a permanent, compact build, the Nano R3 is your best friend.
