STM32 4 Channel Audio Board - fully assembled

What is it?

This is a small (2" x 2.5") board with an STM32F105RBT6 MCU, a pair of CS4344 audio DACs and a variety of I/O resources to support development of embedded audio synthesis applications.

Software Development

The STM32 family of parts are supported by a variety of commercial IDEs, all of which are available in low-cost or limited free versions from the ST website.

I prefer to use open-source tools, so I've set up a development environment based on the GNU C compiler for ARM, available for free from Mentor/Codesourcery. For downloading to the target I use an STM32F4 Discovery board with stlink V2. To ease development I also use the STM32 Standard Peripheral Library to as a starting point for my code and then optimize out the heavyweight functions as required. Links to all of these are here:

Getting One

Interested? Contact me at the email below and I'll give you a link where you can buy bare boards directly from the PCB fab. Cost for boards is about $8/ea, but with setup and shipping expect to pay a bit more. Parts will run another $10 or so depending on where you get them and which version of the processor you want.
