Prototype Board for STM32

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.

    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.
