Introducing the Lil' Nardo!
The Lil' Nardo is an Open Source, fully Arduino Leonardo compatible development board, in a bite size package.
We had a need for a compact Arduino compatible board, with built in USB. The functionality of the Arduino Leonardo was perfect for what we wanted to do, however the Arduino Leonardo's size was too big for our project. So we designed our own smaller version.
We wanted to created a miniature USB capable board that is both inexpensive, expandable and completely Arduino compatible...so we did.
Stretch Goal - $7500
Since we are on track to hit our goal early, We wanted to add our first stretch goal. If we can reach $7500 we will give everyone who ordered a Lil' Nardo a breakout/prototyping shield.
Operating Voltage: 5V
Digital I/O Pins: 20
PWM Channels: 7
Analog Input Channels: 12
DC Current per I/O Pin: 40 mA
DC Current for 3.3V Pin: 50 mA
Flash Memory: 32 KB (ATmega32u4) of which 4 KB used by bootloader
SRAM: 2.5 KB (ATmega32u4)
EEPROM: 1 KB (ATmega32u4)
Clock Speed: 16 MHz
Why the Lil' Nardo?
We loved the ease of use of USB for the Arduino Leonardo. What we have created is a board that can provide that same functionality in a smaller package at a price point that allows you to leave your board in your project.
How do you upload sketches?
All you need to program the Lil' Nardo is a USB cable. It programs exactly as you would a Leonardo. The Lil' Nardo doesn't require a special programing board to upload your sketch.
Adapter for full size shields
We have build a special adapter board to make the Lil' Nardo compatible with full size shields. This adapter adapts the LIl' Nardo to the Arduino shield, version R3. If your shield works on a standard Arduino Leonardo then it will work with the Lil' Nardo and the adapter.

What you will receive!
When you receive your reward, there will still be a little bit of work needed before you can get your project up and running. The through hole components (The 2 headers along the sides and the 3 pin right angle header in the middle) will be shipped to you along with the Lil' Nardo and will need to be assembled by you. The components that need to be soldered are shown in the picture below. The 3 position right angle header is the only header necessary for the Lil' Nardo to run. This header will select the power input source. After you solder the header on, place the shunt on the two pins labeled 'USB' for powering the Lil' Nardo directly from the micro USB connector. Then you'll be good to go!
There will also be two headers shipped to you, a 14 pin and a 16 pin. In the hopefully not too distance future, we'll be making shields that would connect to them. However, they are completely optional for your project!
We've also added a reward option to have the through hole components soldered for you. If you don't want to solder yourself, you can have us do it for you!
What is left to do?
Initial Design: DONE
Production Run: This is what we need your help for!
End of February - Our kickstarter ends and we'll begin ordering the PCBs and arranging for component assembly. We'll also order the through hole headers.
April - We expect to have all of the PCBs in house and we will begin to program the necessary bootloader onto the ATMEGA32U4. Each Lil' Nardo will then be tested for quality.
May - We will begin shipping the Lil' Nardos to all of you awesome people that helped make our project successful!
Who are we?
We are a bunch of experienced engineers who are trying to bring our love of tinkering to a broader audience.
Risks and challenges
The challenges in this project come from manufacturing. From experience in our professional lives we understand the risks involved with manufacturing circuit boards. The main risks stem from delays in the manufacturing and shipping processes. Allowing extra time for thorough testing of each device we send out will help mitigate the risk involved in handling manufacturing problems.Learn about accountability on Kickstarter
