Description: Replacement: None. We are no longer selling this development board, but check out our ARM development category for some other options. This page is for reference only.

The ARM Cortex-M3 processor is the latest generation of ARM processors for embedded systems. It has been developed to provide a low-cost platform that meets the needs of MCU implementation, with a reduced pin count and low-power consumption, while delivering outstanding computational performance and an advanced system response to interrupts. The ARM Cortex-M3 32-bit RISC processor features exceptional code-efficiency, delivering the high-performance expected from an ARM core in the memory size usually associated with 8- and 16-bit devices.

The STM32F103 performance line has an embedded ARM core and is therefore compatible with all ARM tools and software. It combines the high performance ARM Cortex-M3 CPU with an extensive range of peripheral functions and enhanced I/O capabilities. STM32-P103 is good start-up board for learning the new ST Cortex-M3 based microcontrollers STM32F103RBT6. This board has RS232, USB and CAN connections. The prototype area with all microcontrollers port pins broken out allows easy implementation of add-ons.

Customer Comments

  • Is their an enclosure for this board? Anywhere…

  • It appears the the USBLC6 is missing (for my board at least). Is this necessary for protecting the Host (my computer)?

  • Uh… Why do you have an ASCII-Art picture of this board? You can’t see any detail in it…

    • We have ASCII for all product images on the website. It’s not for details, more just for amusement. :)

  • I just got my Olimex board and it is a beauty! I put it in a custom enclosure from protocase and am ready to start building! First up, data capture/ oscilliscope.
