What is a prototype?

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.

Functional Prototype

Demonstrates the functionality of the final product, but looks different.

Appearance Prototype

Looks like the final product, but is not functional.

Design Prototype

Appearance and function match the final product, but is made with different manufacturing methods.

Production Prototype

Appearance, function, and manufacturing methods match the final product.

About

Our hassle-free, out-of-the-box solution lets you pipe data from any of your sensors through one or several LPWAN operators of your choice, then manage and visualize this data online.

 The vast majority of LPWAN solutions offer only hardware. We give you more, a complete ecosystem that integrates all the different technologies seamlessly: 

  • A ready to use development board in an IP66 enclosure so you can leave it outdoors, this is the PLD (Place and Leave Device)
  • A SaaS platform called HL2 Panorama: all the data your are sending over LPWAN is accessible in one place
  • Our solution can work with any LPWAN technology (Sigfox™ or LoRaWAN™) and any operator.
  • The device design is compatible with Arduino™: we deliver a full open library on a GitHub account, feel free to participate!
  • You can connect your own sensors (temperature, pressure...) through a dedicated connector; we provide examples
  • Everything is secured: we use encryption to protect your data
  • Long data packets are segmented to be sent through LPWAN networks
  • The PLD can be powered using a standard lithium battery which provides as long as 10 years of power

Each PLD is an LPWAN device that contains our own software on top of the standard Sigfox™ or LoRaWAN™ modem stack. In this way, we are able to add smart new features such as ciphering, packet segmentation, reassembly and operator management.   

On the other end, our SaaS platform implements operator specific protocols. Device data from any operator is centralized in one place, regardless of the operator used.

Our unique SaaS platform offers a reactive and modern user interface to manage the LPWAN devices, and a standard REST API to easily integrate the PLD devices into your own software environment.

What's inside the enclosure? Well, enough space for a board and a battery holder.

The board itself is composed of an Arduino™ compatible microcontroller linked to an LPWAN modem through a serial port. The following illustration shows the peripherals surrounding the processor:

  • Two expansion headers
  • A Molex connector specifically used to connect an I2C sensor
  • Test input/output connectors

A unique feature is that the sensor is powered through a dedicated power supply to keep the consumption low by switching off the VCC rail. The Molex connector also has a GPIO line that can work as an interrupt.

Developer shield

The PLD Developer kit contains a top board, called a shield, used for firmware development. You can connect any Arduino™ compatible programmer (provided with the Developer kit) and there is a tiny breadboard area used to solder any piece of test hardware such as your own sensors.

 

We have built an Arduino™ compatible library called PLDuino. This firmware will help you manage the peripherals and the LPWAN modem by offering you an easy way to send and retrieve messages.

Here is a simplified view of the firmware and hardware architecture.

We have strived to lower the consumption of the device as much as possible. Our advanced power management system is built using:  

  • A specific low power Atmel microcontroller variant
  • A modem-dedicated switchable regulated power supply
  • A sensor-dedicated switchable regulated power supply
  • An FRAM-dedicated switchable regulated power supply
Our SaaS platform allows for quick application development through an intuitive graphical user interface:  

  • connect and manage your devices  
  • create application dashboards with the provided visualization widgets
  • define shared or specific products (data models)

Need to manage multiple accounts, dashboards and teams with specific permissions? Our Organizations feature has got you covered.

You’re just a few clicks away from your live dashboard!

Seamless data integration

We’ve built a standard REST API that fits any workflow.  

It gives you access to an Elasticsearch™ analytics engine to search and analyze your data.  

Keep what you have, add what you need: you can choose the level of integration with your existing solution, or even start from scratch using our modules exclusively. 

Anyone can create a free-of-charge account. Each product bought through this campaign will come with a 1-year subscription to the operator of your choice.

After one year, you will need to purchase a new subscription at a competitive fee, tailored to your needs.

The LPWAN wireless system makes use of the unlicensed frequencies that are available worldwide. The most widely used frequencies / bands are:

  • 868 MHz for Europe
  • 915 MHz for North America (Not supported yet)
  • 433 MHz band for some Asian countries (Not supported yet) 

Beware! The device you will order with this campaign is only available in 868 MHz version.

 

With our solution, you can forget about the technologies involved in LPWAN networks because we have simplified the choice for you.

We are integrating all the network operators we can so you can decide, and change at a later time, which is your operator.  

When you order a PLD, you will be asked to choose between 4 network operators (Sigfox™, Loriot™, Orange™ and TTN™).

1 This may be limited by the base station capabilities  

2 Depends on the payload size. A calculation sheet is available

By launching this campaign we are hoping to fulfill three goals:  

1. First, the more feedback we get from people using our ecosystem, the faster we can improve it and offer features that are really needed by the users;

2. Then, we're hoping to build a community of makers, exchanging ideas and designs around our solution to help it grow; 

3. Finally, we need some money to develop new things. This part is explained deeper below.

(And we also need a new coffee machine for our developers).

The PLD hardware is nearly finished but we need some time to improve the firmware and offer more drivers and applications to the Arduino™ community. It will cost us some internal development time and some resources to manage the community contributions.

We also need to prepare for selling in a traditional way: we need proper packaging, an official barcode, and need to order specific cables for the PLD connectors.

Finally, the money will be injected towards the HL2 Panorama SaaS platform, in charge of managing the IoT devices and using the data. The community has an important role to play here, too, by helping us find the right direction: what needs to be developed first for you, the users.

We have elaborated several packs that contain everything for you to develop an application using the PLD and the sensor of your choice.

Developer Edition PLD

This kit contains the materials you can see on the image below plus:

  • A one (1) year subscription to the operator of your choice: Sigfox™, Orange™, Loriot™ or The Thing Network™ 
Everything is included so you can start to develop your IoT application at once.

Alkaline Core Edition PLD

This edition contains only the PLD enclosure without the developer accessories:  
  • The PLD enclosure (parts 1, 2, 3, 8, 9, 10)
  • The alkaline battery pack (parts 4 and 5)
  • A 1-year subscription to the operator of your choice

Lithium Core Edition PLD

The core edition can also be ordered with a Lithium battery (Saft LS33600) instead of the 4 AA battery pack. It will offer you 17Ah of energy!

    CAUTION! Misuse of a lithium battery may lead to hazardous results such as high temperature buildups and even explosions. Restrictions apply to the disposal of lithium batteries. You may prefer to use alkaline batteries during the development and testing phases of your applications. Please contact us if you have any question regarding the use of lithium batteries.

Ultimate Edition pack

 

This pack includes everything you need to create your own network. It includes:
  • A developer kit 
  • 4 alkaline PLD packs  
  • A Multitech™ gateway (MTCDT Conduit + board MTAC LoRa868), preconfigured
  • A 1-year subscription for all the devices and the gateway

We will start to order the PLD and boxes before the end of the campaign to be sure to have the equipment ready at the desired date (roughly during September). Some components may take longer to deliver.

Early birds will be luckier: we will ship our current stock as soon as the campaign ends.

 

We are committed to deliver quality products on time. To achieve this goal, part of the production will be subcontracted to reliable and experienced partners. We have also developed an automated process for production testing.

 

Pictured below is an early version of our PLD: the enclosure was bigger and the electronics were a sandwich of standard Arduino™ boards and shields.

This was the basis for testing the concept and starting the development of drivers and embedded code.

Risks and challenges

The PLD is the latest version of our concept, which has already been tested on the field, and is currently being evaluated by some customers. The product is Sigfox™ certified.

Building a highly available and intuitive SaaS platform is a big challenge. We trust our talented engineers, and your feedback, to help it grow.
We're hoping for a lot of customers and users to help us correct things and add new wonderful features you've always wanted to see.

We would be happy to be challenged by large amounts of orders! We have limited experience in the field of e-business, but we're charged up and ready to take this on!

As with any innovative project involving hardware and software, although we’ve paid a lot of attention to the quality of our products, there is always a risk of finding some defects or bugs. Our support team is committed to solving these issues as quickly as possible, and provide best effort support.

In other words, HL2 is “Big enough to make it, small enough to care about it” and we will be thrilled to share this success story with you.
