The MISL Architecture Design, Development, and Deployment Pathway is a partnership with NASA's Controls and Data Handling Branch located at Johnson Space Center in Houston, TX. The architecture provides space-qualified, rack-and-stack layers that allow embedded systems developers to quickly create the hardware platform that meets the specific requirements of the project.
The objective of the MISL Stack is to create small microcontroller applications that work in a system that is modular, scalable and reconfigurable. The ability to quickly prototype designs that are rich in features is a key goal in the creation of the MISL Stack.
It was decided that the best way to take advantage of MISL's modular, scalable, and re-configurable architecture was to make it Open Source. On this site, there are numerous board designs that have been released to the public for anyone to use. By releasing this to the open source community, we hope to see new innovative designs and software created that can be utilized in future NASA projects.
NASA developed the MISL system to provide a quick, inexpensive solution for our "80 percentile" customer in the small, low criticality microcontroller area. A goal was to maximize its use in harsh environment while minimizing costs. All of NASA's designs utilize industrial temperature range parts (-40 C to +85C). The mechanical design can withstand most launch acceleration and vibration environments with nominal protections. Several of the modules have been tested for both low earth orbit and deep space radiation environments and are acceptable to use in low criticality applications. With nominal thermal and mechanical designs, the MISL system can provide solutions in moderately harsh space environments.
The areas not serviced by this system include: extremely small, extremely low power, very high processing power and extreme environments. For those areas, we provide custom designs which tend to be very expensive and long lead.
NASA has several MISL applications that have been certified for space flight. These applications are both internal and external to the crew habitable environments.
The MISL Bus Architecture was designed by NASA, and is kept consistent throughout all board designs. the MISL standard focuses on two connectors, the Power and Data Bus connector. By clicking on the following images, you can see how each of the connectors break out, and also what boards are currently utilizing what pins.
The following table provides specific information about the MISL boards and some of the projects that this architecture has been used to support. If you would like a overview of each board, please click this MISL Overview Link.

For the past few years, the partnership with NASA has allowed various capstone projects to utilize the MISL Stack to create prototype systems for real world problems. This unique experience is referred to as ESET 419 and ESET 420, or Capstone. The following teams have or are currently utilizing the MISL Stack to complete their Capstone course.
is an Aggie owned and operated engineering consulting firm based out of College Station, Texas. We are pleased to be working with Texas Space, Technology, Applications, & Research (T STAR) who is sponsoring a CubeSat communications project. DVDT will design, develop, and deliver a prototype system that is capable of communicating between a TSat, CubeSat class vehicle designed by T STAR, and a base station. This development will be incorporated into the existing MISL Stack system through the generation of a new MISL layer to aid in the development of a turnkey TSat architecture. DVDT is excited to be working with Professor Mike Willey as our senior advisor throughout the project.
is a tech start-up based out of College Station Texas whose focus is expanding the functionality of the Modular Integrated Stackable Layers(MISL) system and finding interesting ways to implement this modular technology in new applications. Our current project is the development of a cellular data layer of the MISL stack system that we are integrating as the primary method of control of a LEGO Mindstorm platform.
Eagle Embedded Engineering
(EEE) is an Aggie owned and operated engineering consulting firm based out of College Station, Texas. EEE is currently working with NASA and MISL Labs, our sponsor, to design an Ethernet communications layer for the MISL Stack. This layer will function as a 100Mbps layer two network switch for communications between 4 devices.
