INTRODUCTION:

STM32-P103 board is development board which allow exploring the complete features of
the new ARM Cortex M3 STM32F103RBT6 microcontrollers produced by ST
Microelectronics Inc.
The board have SD/MMC card connector and allow USB Mass storage device demo to be
evaluated. The RS232 driver and connector allow USB to Virtual COM port demo to be
evaluated. The CAN port and driver allow CAN applications to be developed. The UXT
connector allow access to all other UEXT modules produced by OLIMEX like MOD-MP3,
MOD-NRF24LR, MOD-NOKIA6610 etc to be connected easily. In the prototype area
customer can solder his own custom circuits and to interface them to USB, CAN, RS232 etc.

ELECTROSTATIC WARNING:

The STM32-P103 board is shipped in protective anti-static packaging. The board must not
be subject to high electrostatic potentials. General practice for working with static sensitive
devices should be applied when working with this board.

BOARD USE REQUIREMENTS:

Cables: 1.8 meter USB A-B cable to connect to USB host.
Hardware: ARM-JTAG, ARM-USB-OCD, ARM-USB-TINY or other ARM JTAG

compatible tool

Software: ARM C compiler and debugger software, the possible options are:

- free open source platform: GNU C compiler + OpenOCD and Eclipse
(support all low cost Olimex JTAG debuggers)

- commercial solution EW-ARM from IAR Systems AB, require
expensive J-LINK debugger

- CrossWorks from Rowley (supports all Olimex low cost JTAG
debuggers).
