Released in 2009, USBizi was the very first single chip NETMF solution. It was a great challenge due to the limited resources available on micros back then. With a lot of optimization, we got the complete NETMF with file system running nicely on USBizi. Unfortunately, there was not enough resources to add graphics and networking support.
Today, we offer the Cerb-family which is based on the STM32F4 micro, which is 100% open source, the hardware and the software. Customers can now create products using STM32F4 processors and use our software free of any fees or royalties. The software is provided under the Apache2 license, allowing for very flexible use, even for commercial applications. You only need to provide proper attributions.
Starting today, USBizi is a Legacy product. If you are using it in one of your designs, not to worry. We will continue to offer USBizi for months to come. We recommend the use of the G120, or even the G400 modules for future designs, which are a lot more powerful. For simpler applications, we recommend the use of our open source software on STM32F4. In the far future, if we decided not to sell or license USBizi anymore, we may release the binaries as open source.
FEZ Panda II is also legacy and available while supplies last, with possible future orders with minimum quantities. Of course, the FEZ Panda hardware is open source allowing anyone to use USBizi to rebuild more FEZ Panda II. We recommend FEZ Cerbuino instead of FEZ Panda II. FEZ Cerbuino comes in different flavors and, while keeping the arduino-form-factor, it supports .NET Gadgeteer. This allows FEZ Cerbuino to be easily used with the many available modules.
