The Nano IO Expansion Shield V3.0 takes a classic 30-pin Arduino Nano and brings every pin out to labelled ground, power and signal (G/V/S) header rows, so servos, sensors and modules plug straight in with ordinary 3-pin leads. It also has 4-pin I2C and serial headers, a 3.3V header, a DC barrel jack, a reset button and four mounting holes. It fits our Nano V3 USB-C board and other Nano-footprint boards; the Nano is sold separately.

Nano IO Expansion Shield V3.0 (blue)

Fully assembled with headers fitted. Arduino Nano not included.

Great for

Plugging SG90 or MG90S servos straight onto pins D9 and D10
Wiring 3-pin sensor modules without a breadboard
Hooking an OLED or other I2C module to the 4-pin I2C header
Screwing a Nano project down inside a case or onto a robot chassis
Classroom kits that get plugged and unplugged many times
Running a Nano project from a 9V plug pack through the DC jack

Wiring & getting started

  1. Seat the Nano the right way round

    Match the pin names on the Nano (D12, D13, VIN, TX) to the names printed beside the two sockets, then press it in evenly. The Nano needs male header pins on its underside.

  2. Plug in by colour

    On each 3-pin row, G is ground, V is power and S is the signal pin. A servo lead goes brown or black on G, red on V and orange or yellow on S.

  3. Upload as normal

    Program the Nano through its own USB port, choosing Arduino Nano in the Arduino IDE. The shield adds no drivers or code.

  4. Add a supply for bigger loads

    The V pins share the Nano's 5V. One small servo such as an SG90 runs fine from USB. For more than one or two small servos, feed their red leads from a separate 5V supply instead of the V pins, and join that supply's ground to a G pin.

Frequently Asked Questions

Answers to the questions buyers ask most.

Does it come with an Arduino Nano?
No. This is the shield only. Our Nano V3 USB-C board fits it, and needs its header pins fitted (choose the soldered version if you do not want to solder).
Which Nano boards fit?
Any standard Nano V3 layout with two rows of 15 pins, 15.24mm apart, including ATmega328P and ATmega328PB boards with USB-C or Mini USB. The Nano SuperMini, Nano Every, Nano 33 IoT and Nano ESP32 do not fit.
What do G, V and S mean?
G is ground, V is power and S is the signal pin for that row. A servo lead goes brown or black on G, red on V and orange or yellow on S.
How many servos can I run?
The V pins share the Nano's 5V. From USB, run one small servo such as an SG90. When the DC jack powers the Nano, the Nano's own 5V regulator still feeds every servo, so for more than one or two small servos, power them from a separate 5V supply with its ground joined to a G pin.
What can I plug into the DC jack?
A centre-positive DC plug pack, 7 to 9V suggested and 12V maximum. The jack feeds the Nano's VIN pin through a protection diode, so the Nano's own regulator makes the 5V.
Can I mount it in a case?
Yes. It has four mounting holes of about 3.2mm, which suit M3 screws or standoffs.

Why Buy from NZN

Useful parts, fair prices and someone local to help.

I'm Lukas, an engineering student and maker based in Te Awamutu. NZN grew out of a CNC build that dragged on for months because every missing cable, bolt or electronic part meant another overseas order. I started the shop so Kiwi makers can spend more time building and less time waiting for the next parcel.
