STM32 Nucleo boards

STMicroelectronics (STMicro) announced their new line of STM32 mbed-enabled development boards, the STM32 Nucleo! They look like they are planning a full line covering the STM32 Microcontrollers. 

The new STM32 Nucleo boards are mbed-enabled, and support Arduino connectivity while also providing ST Morpho extension headers that allow access to all of the microcontroller’s on-chip peripherals. As an mbed-enabled board, developers can make use of the mbed open source software platform, online tools and collaboration infrastructure at mbed.org. The board’s Arduino headers accept shields from the extensive Arduino ecosystem, allowing developers to add specialized functionality quickly and easily.

The first four STM32 Nucleo boards, supporting the STM32 F1, L1, F4, and F0 Value lines. cost looks to be about $10.32.

Robotics 101 Part Two

OK it been a few weeks but Sparkfun has come out with a few more of video series on robotics. So here are next three. 

Part four Transfer of Motion from SparkFun Electronics, Inc. Robotics 101 Series is they discuss the advantages and disadvantages to using gears, pulleys, and chains in your robotics projects.




Part five Precision Motion from SparkFun Electronics, Inc. Robotics 101 Series they discusses the differences between precision and accuracy, when you might prefer one over the other, and how different motors offer different solutions in your project.

Part six Mechanical Structure from SparkFun Electronics, Inc. Robotics 101 Series they describes a few of the more popular materials for building your robot, goes over the pros and cons of each, and offers solutions for some off the shelf alternatives.
