The Sain Smart Nano for Arduino is a surface mount breadboard embedded version with integrated USB. It is a smallest, complete, and breadboard friendly.

  • Automatic reset during program download
  • Power OK, blue LED, Green (TX), red (RX) and orange (L) LED Auto sensing/switching power input
  • Small mini-B USB for programming
  • Serial monitor ICSP header for direct program download
  • Standard 0.1" spacing DIP (breadboard friendly)
  • Manual reset switch Power: The Nano can be powered via the mini-B USB connection, 6-20V unregulated external power supply (pin 30), or 5V regulated external power supply (pin 27). The power source is automatically selected to the highest voltage source.

The Sain Smart Nano for Arduino is a surface mount breadboard embedded version with integrated USB.
It is small, complete, and breadboard friendly.
It has everything that Diecimila/Duemilanove has (electrically) with more analog input pins and onboard +5V AREF jumper. Physically, it is missing power jack.

The Nano is automatically sensed and switched to the higher potential source of power so there is no need for the power select jumper. Nano's got the breadboard-ability of the Boarduino and the Mini+USB with smaller footprint than either, so users have more breadboard space. It's got a pin layout that works well with the Mini or the Basic Stamp (TX, RX, ATN, GND on one top, power and ground on the other).

This new version 3.0 comes with ATMEGA328 which offer more programming and data memory space. It is two layers. That make it easier to hack and more affordable. You end up paying less with Nano than Mini and USB combined! Specifications: Microcontroller Atmel ATmega328 Operating Voltage (logic level) 5 V Input Voltage (recommended) 7-12 V Input Voltage (limits) 6-20 V Digital I/O Pins 14 (of which 6 provide PWM output) Analog Input Pins 8 DC Current per I/O Pin 40 mA Flash Memory 32 KB (of which 2KB used by bootloader) SRAM 2 KB EEPROM 1 KB Clock Speed 16 MHz Dimensions 0.70" x 1.70".

Great for Beginners

I bought one of these boards about two months ago and it has worked perfectly well. Every project I have done with it has been really easy to execute and to program it unto my Nano. The only drawback that I have ran into is that if you want to get an in depth feel of how to use a microcontroller, it offer very few possibilities to program in an assembler language. Other than that it is a perfect board to start getting into electronics.

Works great

I have bought 3 and all worked with no problems. They are really good controllers for my quadcopter. I will buy other tools in your store if needed.

Will come back

It is fully assembled for the Arduino, it works well. Also, the price is OK.


It is fully assembled for Arduino. I have used it for several days and haven’t had a problem so far.

Good stuff.

It's simple and good.

Good, small, cheap, Arduino compatible

I haven't done extensive testing yet, but this Chinese Arduino compatible (clone ... lets admit that's what it is) seems to be a quality item. These guys do not say Arduino anywhere on the PCB, so the people yelling about clone on eBay don't belong here. It is clearly marked as SainSmart, so I would consider this an above-board compatible. I ordered 2 and they both work and have been going though "burn-in" for hours. THE BAD : 1) One word - Documentation - I don't find documentation specifically for this board, except for the catalog page. They talk, for example, about blue and orange LEDs, but I only see green and red on the board. At my age, the microscopic lettering on the PCB is way to small to read. They need documentation that is separate from the actual Arduino Nano, least on the web site, and it needs to be correct and up-to-date. 2) The pin headers seem to only come attached. I'm used to separate (pin and ICSP) headers that I can attach if I want. This is something of a nit-pic, but it would be good to have an option . OVERALL : I like it. It's a clean, small, working (USB) Arduino compatible, with a price that doesn't make me shutter to embed it in a project.

Works fine with Arduino

It's fullly compatible with Arduino and with a good price. With Nano I built circuits without to much components, very simple to connect.
