INTRODUCTION
STM32-P103
board is development board which allows you to explore thee features of the ARM Cortex M3
STM32F103RBT6 microcontroller produced by ST Microelectronics Inc.
The board has SD/MMC card connector and allows USB Mass storage device demo to be evaluated. The
RS232 driver and connector allows USB to Virtual COM port demo to be evaluated. The CAN port and driver
allows CAN applications to be developed. The UEXT connector allows 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 the customer can solder his own custom circuits and interface them to USB, CAN, RS232
etc.
STM32-P103 is almost identical in hardware design to STM32-P405. The major difference is the
microcontroller used (STM32F103 vs STM32F405).
Another board with STM32F103 and a display is STM32-103STK. A smaller (and cheaper board) with
STM32F103 is the STM32-H103. Both boards mentioned also have a version with the newer microcontroller
STM32F405 used. The names are respectively STM32-405STK and STM32-H405.

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:
Hardware:
USB A-B cable (up to 1.8 meters) to connect to USB host.
Any ARM JTAG programmer or debugger with standard 2×10 pin JTAG connector. You can
use one of the Olimex ARM JTAG debuggers: ARM-JTAG, ARM-JTAG-EW, ARM-USB-
OCD, ARM-USB-OCD-H, ARM-USB-OCD-TINY, ARM-USB-OCD-H.
Note that Olimex OpenOCD debuggers lack SWD interface by default. There is the adapter
ARM-JTAG-SWD
that adds SWD to any of the programmers/debuggers mentioned
above.
Additionally you can use our
ARM-JTAG-COOCOX
debugger which has both JTAG and
SWD interfaces and works with CooCox IDE natively and with Keil uVision via plug-in.
Note the board can be programmed without a debugger using a serial cable with level shifter
and the software provided by ST (STM32 Flash Loader demonstrator).
Software:
ARM C compiler and debugger software, among the possible options are:
-
-
-
-
The free open source platform: GNU C compiler + OpenOCD and Eclipse (support all
low cost Olimex JTAG debuggers)
The free CooCox IDE – good choice for ARM Cortex microcontrollers
The commercial software IAR EW for ARM from IAR Systems AB
The commercial software CrossWorks from Rowley – supports all Olimex low cost JTAG
debuggers and features of number of examples for Olimex boards
