We love to play with Arduino and like it very much but one thing have always bothered us – it’s HUGE.
What you do when you want to make small data logger, RF/Zigbee baecon, sensor network, something wearable etc? use this BRICK? No way.
This is how the idea for OLIMEXINO-NANO came.
We made complete Arduino replacement with size of only 30x30x8 mm
What you see on the pictures above is TOP and BOTTOM view of the OLIMEXINO-NANO.
It have these features:
- ATMega32U4 processor (Leonardo compatible)
- micro USB connector for programming and power supply when debugging
- RESET button
- USER button
- microSD card connector for data logging on SD-card
- UEXT connector for RF, Zigbee, Ethernet, RELAY, RGB LED, etc UEXT modules
- two status LEDs
- Connector 14 pin 0.05″
- Connector 20 pin 0.05″
the connectors allow other boards to stackup like normal Arduino shields.
The first shield we made is with Battery power supply:
On this battery shield there is:
- power ON/OFF switch
- LiPo battery connector for our 1400mA/2200mA/3000mA/4400mA/6600mA batteries
- LiPo charger with three status LEDs
- Li 3V CR3023 battery holder
Here are how NANO and BATTERY shield snap together:
both fit perfectly in this small plastic enclosure:
The next shield was to allow easy connection to Breadboard:
Here is view of BreadBoard shield with Battery shield snap on top:
And here is same with NANO snap on bottom:
and here is side view:
Here is again how NANO looks next to OLIMEXINO-328 (Arduino-2009 clone)
and to cigarette lighter:
and together with the small 45 x 40 x 20 mm enclosure:
As you see above these three boards are the first prototypes which we built, now we will do some testing and run production in November. The prices? They will be very competitive and similar to OLIMEXINO-32U4 which uses same processor.
Another shield we work now on is Bluetooth 4.0 BLE shield which to snap and to allow trouble free connection to iPhone and Android devices

Great work guys! Congratulations!!!

Looks cute, but I can’t help but find that the UEXT connector looks misplaced on this board, since it makes it unnecessarily bulky. Maybe choose a smaller connector and provide an adapter cable to UEXT? Also, this would be nice to have with a better processor like in Duinomite. Also, it would be great if after your BT 4.0 LTE module, you’d make a board for nano SIM cards. I like this form factor: http://www.engadget.com/2013/10/02/huawei-ultrastick-3g-sd-card/

I have written a short blog about your product wiht a link back to this post, here is the link and this sin an excellent Arduino! http://circuitpunk.wordpress.com/2013/10/11/look-mom-i-shrunk-the-arduino/

If you guys ever do an Ethernet NANO shield ( and I know you will ), please make one with those fancy mini-ethernet connectors. There is no point it a tiny uC with tiny stacking expansion boards that have HUGE connectors !
I also second Miik about the need of a refactored form-factor for the UEXT … How about ( duh ) NANO-EXT ?
Otherwise, great news if you guys and girls are getting on the micro Arduino bandwagon !
Keep up the good work !

I find it very pretty but … the grade of hack-ability is low. Is ok if someone can buy shields from you, but not anyone can build his own shield for this board.
I also think that UEXT connector looks weird but is better regarding to electric contact and reliable.

if one can build shiled for Arduino I do not see reason to be not capable to build shield for NANO, there is no difference and equally easy
Oct 14, 2013 @ 15:39:59
you know how many complains received Arduino team when they used a smd micro in Arduino UNO?
SMD is a huge matter for the majority of the people in the hobby zone. First of all, there are difficulties in making a PCB to that size using toner transfer. Second, it will be alignment problems when soldering the connectors (they are double rows – double difficulty, unless you connect them to the Nano board before soldering them to the shield). Thiird, any smd smaller than 1206 size is frightening.
So, I sustain what I said before.

A great idea, but why not base it on an STM32F103 like the leaf labs mini and OLIMEXINO-STM32 and use the leaf labs IDE? My recent projects have run out of processing power and ADC resolution with arduinos and Batsocks boards (the XMEGA ADC sucks) and moving to a leaf labs mini clone has been a pleasure. From what I can see the price would be almost identical too.
Even better you could then, with little extra work, do a version with the almost pin compatible STM32F30X and add an FPU and a 16 bit ADC.

F103 have much more GPIOs so more connectors will be necassary and maybe the design will be not so compact, but anyway good idea for future product 😉
Oct 14, 2013 @ 18:10:26
The mini uses a 48 pin chip, like yours … maybe both could share the same shields?
Oct 15, 2013 @ 11:55:04
Can You make a shield with the TI CC3000 low power Wifi chip?
Can cohexist the battery shield and another shield for connectivity?
Oct 15, 2013 @ 13:59:01
Is it possible to use more than one battery shield for extended off-grid life?

Are the shields stackable somehow?
For example put on the same nano 1 battery shield, 1 bluetooth shield and 1 weather shield? (for example to make a nano remote weather station?)
Does the UEXT connector allow daisy chain between shields?
Oct 18, 2013 @ 20:04:58
the shields are stackable as they have male connectors on bottom and female on top so you can stack them
Oct 20, 2013 @ 17:45:07
How do I make my nano remote weather station?
How do I access the stacked different shields (weather and temperature) from the nano code? Thank you!

when will it be available on the market ?

Hi guys,
I’m sorry if asking something obvious, but at what voltage do the nano and nano-bat work? I have only seen 3V mentioned – do these work on 5V as well?
Best,
jake

Where did you get the plastic box?
