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

The story

We got determined to build a big brother to development boards. Arduino allowed hobbyists to develop code easily. It created a community, and we decided to give our share. Many different boards were born, but rarely a board was designed that was well-protected for more real experiments and projects. We especially liked a board with automotive applications (We are not promising any standards! The board is still provided as is). And so... Stronghold was born! It is the strongest development board made! By employing an Atmega2560 microcontroller, Stronghold can be easily used like any Arduino board, and can be programmed by Arduino IDE. Thus, Stronghold is Arduino-enabled.

The three options
The three options

Easy to use

We will provide you with a quick start-up guide that will have you running basics in a matter of minutes. You will have information necessary to run every section of the board. You will simply make the power and USB connections, install necessary software, and start working.

One of our goals, however, is to ensure that Stronghold can be used for production as well. Once the basics are covered, you can explore the capabilities of Stronghold one by one, and connect the dots together!

The microcontroller can be programmed using USB or ISP. You can even include additional LUA code that resides in a maximum 20MB flash and runs through AT commands.

The Specs

  • Atmega2560 microcontroller
  • Powered by external source through protection
  • Build-in USB. Can detect USB connection in firmware.
  • Programmable through USB or ISP
  • SIM5320 (GSM/2G/3G/GPS) programmable through USB
  • SMA active GPS and GSM antenna connections
  • On-board 260kHz 3A 5V, 260kHz 3A 4.05V, 100mA 3.3V regulators
  • 3-5 high-current 47A-rated MOSFET outputs. MCU to MOSFET gates are isolated by PS2501L. MOSFET outputs are protected by flyback diode and TVS. Unassembled RC can be used as snubber. Designed and tested to work with concurrent 500mA outputs (Heatsink locations are provided but are unassembled).
  • separate Omron G5LA-14 DC5 safety relay, PTC, 5kw TVS, and trapezoid filter for outputs
  • Protected inputs/outputs for a Wiegand keypad
  • LM62 analog internal temperature • LSM303DLHC accelerometer/magnetometer/internal temperature
  • TVS/GDT/Surge protected RS485 based on fault-protected MAX13442E (Code-compatible with MAX485)
  • Ability to perform fault-protected pulse sensing (K-Line) through MAX13442E • 3-5 TVS/high-rate/range protected analog inputs.
  • Access to 20MB of flash memory through AT commands or LUA programming in GSM module • Voltage reference of 2.5V
  • Additional 1.6A-rated MOSFETS for supply control for accessories.
  • Auto fuse holder, thermal cutoff, PTC, input schottky, 5kw input TVS, input trapezoid filter
  • Programmable through Arduino IDE. Yet, NOT Arduino pin compatible.
  • Possible additional 256kB EEPROM (Not assembled)

Summary of capabilities

  • GSM/GPRS/3G/GPS
  • RS485 or K-Line
  • Protected analog inputs
  • MOSFET-based outputs with safety relay
  • Protection and support for Wiegand keypad (Keypad not included)
  • Over 50 parts dedicated to protection.
  • Would use as low as 10mA when properly set to work in standby mode.
  • A flash for LUA programming with maximum size of 20MB

Where we are now?

  • Design: DONE!
  • 1st prototyping: DONE!
  • 2nd Prototyping: DONE! • 3rd prototyping: DONE!
  • Testing hardware: Limited, will have to continue!
  • Testing Arduino software compatibility: DONE!
  • Testing functionality of each and every component on board: DONE!
  • Fund first production run: It's this campaign!

The community

The open-source world has a wonderful community, and we want to contribute to that. We will provide you with software/firmware for free as much as we possibly can handle, and we will listen to any feedback we receive from backers. Once campaign is funded, we will create a forum and a website to organize all matters relating to Stronghold software development and to provide related resources.

Even though the board is not Arduino pin compatible (Arduino shields cannot be used directly), the system is Arduino enabled, and can be programmed through Arduino IDE. We hope that our contribution to the Arduino community becomes valuable as well.

Additional information will be added to FAQ's once available.

Additional notes

  • Note that server support, service, or access are not part of this campaign.
  • We will provide you with example codes and documentation as much as we can. However, it should be noted that only the hardware defined above is part of this campaign.
  • Accessories not provided by us may not work with Stronghold for many different reasons such as incompatible TTL levels, wrong supply levels, different digital protocols, etc.
  • The enclosure may be subject to change.

Your feedback/Customization

Throughout the project, we like to hear from you. We like to also know if you have specific needs we can cover.

STRETCH GOAL MET: CA $50k - All backers will be provided with detailed example firmware codes.

 

STRETCH GOAL MET: CA $100k - In addition, all backers will be provided with access to a demo server that allows communication with their Stronghold system. Backers will be provided with a phone number that can be used to establish SMS communication with the demo server.

STRETCH GOAL MET: CA $150k - In addition, all backers will be provided with working example PHP/firmware codes that can be used to establish a community-based server/client system.

  STRETCH GOAL MET: CA $200k - In addition, all backers will be provided with working code on firmware that allows establishment of a server/client system, and they will have access to a final server that allows communication with their Stronghold system.

Shipping clarification

The difference in shipment costs arises from distance, weight, and customs requirements in different countries. The enclosed system is specially very heavy and huge!

Note that we are located in Canada, and export to your country could be subject to customs, duty, and taxes. We will send the product to you by proper documentation, and backers may need to cover customs expenses.

Stuff you can do

Access to easy-to-use and powerful systems means that you can build all sort of cool things:

Here is our patented ( just kidding!) Beer-Controlled Ball Valve System!

Industry risks

We are providing a well-protected development platform to our backers. We have done our research, and we have included in our design protection features that we believe will ensure a wonderful experience for our backers. Circuit protection is actually hard, and is never enough. We cannot guarantee everything. We have done limited testing, but we do not possess the equipment to include full-blown expensive standardized testing. One of our goals is to attract enough funds so that we can claim standards for our backers!

One other critical section of the system is its cellular section. The cellular world is complex and it is constantly evolving. We've done our research and we believe that we have made the right choices, however there are factors we cannot control. That said, we are trying to build a network within the industry to be able to support our backers in the future for applications regarding remote logistics monitoring. This is not part of this campaign, but it is what we want to do for our backers.

Risks and challenges

We have established a supply chain and we are confident that we will be able deliver on our rewards. However, you never know what may cause delays with manufacturing when there is shortage of component, there is national holidays, etc. While we may not be able to promise 100% accuracy on delivery dates, we like to promise complete transparency. We believe that we'll be able to keep our backers informed and up-to-date on our progress.

Note that we are located in Canada, and export to your country could be subject to customs, duty, and taxes. We will send the product to you by proper documentation, and backers may need to cover customs expenses and country-specific taxes.
