A prototype is a preliminary model of something. Projects that offer physical products need to show backers documentation of a working prototype. This gallery features photos, videos, and other visual documentation that will give backers a sense of what’s been accomplished so far and what’s left to do. Though the development process can vary for each project, these are the stages we typically see:
Proof of Concept
Explorations that test ideas and functionality.
Demonstrates the functionality of the final product, but looks different.
Looks like the final product, but is not functional.
Appearance and function match the final product, but is made with different manufacturing methods.
Appearance, function, and manufacturing methods match the final product.
Sparrow comes ready with 256-bit TLS encryption, over-the-air updates, and all the ready-made commands you would need to incorporate 2G IoT into your product, work space, or hacked project. All of our code and documentation will be open-source, available on GitHub.
A quick reminder that T-Mobile has made a committment to keep 2G-M2M services running until at least 2020!
What's in the Box? (hint: everything you need to get building!)
Solinius Sparrow 2G (see tech specs below)
SIM800L 2G GSM Breakout
Hologram Global M2M SIM
Data – $40 of cellular data included
Access to our open source firmware including: over the air (OTA) update capabilities, 256-bit encryption, hundreds of abstracted SIM800L commands
Why'd we build the Sparrow?
We were frustrated with all the 2G IoT dev boards out there. The other options are just:
Too expensive - or had recurring (non-data) charges
Built primarily for newbies
Require additional peripherals (like an Arduino or Beagleboard)
Tied to a bloated proprietary infrastructure or cloud network; hacking up tightly coupled code to make it work seamlessly for your specific deployment is time consuming and frustrating.
We wanted a cellular board that would easily scale. We couldn't find one, so we made one.
What makes the Sparrow fly?
Build – Seamlessly build on top of our open-source, abstracted SIM800 functions. No need to mess around with the shoddily translated docs, use ours.
Deploy – Where? Anywhere.
Connect – Connect over the 2G network to gather your sensor data or perform over-the-air updates.
Secure – TLS 1.2 encrypted, keeping your personal data safe from prying eyes.
The programming interface: ISP pogo pads (or 2x3 header).
Why a Sparrow?
Lightweight, global, quick, efficient. Need we say more?
Yeah, we got data. And so do you - each Sparrow ordered will come with $40 of data included. We’ve partnered with Hologram (of Kickstarter fame!), formerly Konekt, to bring global access to your fingertips. Each sparrow flies to your door step with a hologram SIM ready to go (but a reminder: any SIM with M2M/data connectivity will do with some easy APN setting changes).
With over 350 carriers in 160+ countries, where ever you intend to deploy, Solinius and Hologram are here for you. Why Hologram? Because we use them too! Using Sparrow’s technology, Solinius operates our own IoT products in the Democratic Republic of Congo and Uganda. We challenge you to find harsher environments. T-Mobile has made a commitment to keep 2G services in the US running through 2020, so don’t fret if you’re developing for the United States; Good ‘ole Johnny Legere’s got your back.
Use Hologram’s dashboard to activate, track, and manage your deployed IoT devices – a service Solinius uses and trusts on a daily basis.
With each Sparrow, we’ll throw in $40 (!!) of totally free data.
Pop your toaster roughly 27,000 times. Give or take.
Check your pool's water temp 10000 times in a month
Gather intermittent solar panel voltage and current data for over a year
...just to name a few.
After you’ve spent your first $40 on our dime, it still won’t break the bank. Hologram just rolled out new pricing. Click here to read their blog post on it. The greatest thing? For our smallest users, the first MB of data per month is completely free. Just like us, they're looking to scaled deployments, making it easier and more affordable to deploy hundreds of devices globally.
Solinius is a Public Benefit Corporation. Remember that Silicon Valley scene about “Making the World a Better Place”? Well we actually are.
The money garnered from Sparrow goes directly to Solinius’ Ugandan projects, where we’re building the most advanced deployed network of financed solar kits.
Rules we live by:
Provide clean, reliable electricity
Give back to the communities we operate in by providing jobs and sourcing local materials.
That's just one of the reasons why we’ve partnered with mid-western, Chicago based, Hologram.
Be local and make a global impact. Build on!

The team has completed development of the physical board and we are currently in the process of completing our library. Commands used for our in-house IoT operations have been completed and we are well on our way to abstracting the remainder of usable codes. We will not be abstracting the commands pertaining to speaker/call operations, but we would be happy to have contributors submit those following our open-source release!
Risks and challenges
The cellular industry is ever changing. 2G connectivity might lapse, or connectivity in a certain country might become unavailable for a myriad of reasons: political or economic. Make sure to check with your local provider on how long they will be supporting their 2G network. In the US, T-Mobile will operate the network until at least 2020.
The development team is confident in our ability to deliver a working product, with completely sorted code. However, bugs happen, and we'll be sure to update the open-source code, should we find a major bug. We are highly proficient in working with cellular IoT technologies and look to release exactly what you came for on the first go-around.
Solinius will not promise to offer any ongoing tech support for the product or warranty.
Our timelines are pretty conservative, but things happen. Whether one of our suppliers has an unannounced shutdown, or we have a shipping snafu, delays in shipment are possible.
As our video mentions, Sparrow was designed with the "hardcore" user in mind. Intermediate level programmers and experts will feel at home, however beginners might want to start elsewhere as they look to build their IoT knowledge base.
We are IDE agnostic. Backers should be comfortable using the command line.
