The Dallas .NET Micro User Group focuses on the .NET Micro Framework (NETMF) from Microsoft. The group meets on the 4th Wednesday of each month at Improving Enterprises and our meetings are free to attend. Please RSVP according to the monthly meeting announcement to assure plenty of food and drinks for everyone.


What is NETMF?

.NET Micro Framework (NETMF) is an open source platform that expands the power and versatility of .NET to the world of small embedded applications. Desktop programmers can harness their existing .NET knowledge base to bring complex embedded concepts to market on time (and under budget).  Embedded Developers can tap into the massive productivity gains that have been seen on the Desktop.

How small can a Gadgeteer mainboard be? A year ago, we created the FEZ Medusa with 4 sockets. To keep the cost low, at its core, it ran Arduino instead of NETMF, which automatically meant no Visual Studio and debugging capabilities. That was before the NETMF G30 SoC was available. Today we are announcing the FEZ Medusa II with the NETMF G30 SoC at its core. It also includes 6 sockets that are packed with options.

Unfortunately, the current Gadgeteer software core will not fit on the tiny G30 SoC. The FEZ Medusa II will have to be programmed with pure NETMF. This means, no Gadgeteer designer, no plug and play. However, any Gadgeteer driver for any module can modified to use NETMF directly, a simple step but it does require some experience. We even included a entry in the Pins class in the 2015 SDK to make this even easier to port the Gadgeteer driver to NETMF.

The good news is that we are working with Microsoft on the next version of .NET Gadgeteer. A leaner version that will not only fit all NETMF devices, but will also run on Windows 10 devices, such as the Raspberry PI 2. Until then, we recommend FEZ Medusa II to advanced users only.

While not currently available for sale yet, a few of the FEZ Medusas will be available to close customers and community members for evaluation.

Today, we are excited to announce the release of the FEZ Reaper! The FEZ Reaper is the latest .NET Gadgeteeer offering based on the G80 SoC. At 180mHz with 14 Gadgeteer sockets, the FEZ Reaper will have you resurrecting and completing all those projects that are still setting on the shelf!

With the recent release of the FEZ Panda III, the FEZ Lemur, the G30HDR and today, with the release of the FEZ Reaper, we will be putting all Cerb family products in legacy. What does this mean? This means that we have updated the non-commercial Cerb family of products with a newer, more powerful family of products based on the G80 System-on-Chip that comes with a commercial license at no additional cost to you! This means even the world famous FEZ Cerberus Tinker Kit has been updated with the newer and more powerful FEZ Reaper mainboard, making the new FEZ Reaper Tinker Kit. What more could you ask for? For those institutions who still require the FEZ Cerberus and it's cousins, we will continue selling these products until the end of the year or while supplies last.

For those who are new or haven't seen previous newsposts, we have been working very diligently over the last few years to simplify and organize our offerings to create the best user experience possible. To do this, we have decided to start phasing out or redesigning products that were considered to be a hybrid of NETMF and Gadgeteer. In our continued effort to simplify our offerings into Gagdeteer and "non" Gadgeteer product lines, we will also be putting the Cerbuino products into legacy and selling them until the end of the year or while supplies last.

Since we have been talking about new products, here is a recap of the new products announced in recent weeks:

Introduced in 2011, the FEZ Spider was and continues to be the first and most popular .NET Gadgeteer mainboard on the market. Today, we are excited to announce the new and improved FEZ Spider II! The FEZ Spider II was designed using the G120E SoM, the replacement for the EMX SoM. For more details on the G120E SoM click here.

Don't stop reading, we have more great news. The FEZ Spider Tinker Kit has also been upgraded using the FEZ Spider II. All the same great modules and awesome kit with a more powerful mainboard!

For institutions using the FEZ Spider or the FEZ Spider Tinker Kit don't worry, we will continue to offer both products until 12/31/2015. If you have any questions about continued availability please feel free to contact us directly.

Announced recently, the G30HDR, a very small trough-hole version of the surface-mount G30 System on Chip. This allows for an easy way to wire and build projects. It is also DIP format compatible. A socket can be used to plug the G30HDR onto boards instead of soldering. OF course, the male headers must be added first.

As for power, the base microcontroller, the STM32F401, is extremely low power. The G30HDR is designed with no regulator to give the user options when it comes to choosing the right power supply. Especially that STM32F401 can run on voltages lower than 3.3V. The datasheet from ST would cover full details on power consumption and operating voltages.

To power the G30HDR from the USB port, the VBUS signal is exposed on one of the pads. This is the voltage coming from the USB port. This can be used to feed the 3.3V power regulator that feeds the entire system, including the G30HDR itself. As another option, the G30HDR includes the footprint for a regulator that is intentionally left not populated. At 100 pcs or more, the G30HDR can be ordered with the regulator added. However, this regulator is not suited for lower power applications, hence not populated.

Finally, customers can even select to order the G30HDR with headers pre-installed as well.
