Connections and IOs
System Clock
The on-board 8 MHz crystal is used to produce a 72 MHz system clock with PLL.
Zephyr Console
UART2 is used as Zephyr’s console. Default settings are 115200 8N1.
On-Board LEDs
The board has one on-board green LED that is connected to PC12, which is active low.
There is also a red power LED neither connected nor controlled by the MCU.
USB
USB is not enabled by default.
PC4 can be configured as a GPIO input to detect power on the USB port. It is possible to disconnect it by desoldering the appropriate pad in the PCB.
PC11 can be used to disconnect the pull-up resistor on the USB-DP line by setting it high.

Programming and Debugging
This board does not include any embedded debug tool interface, instead you will have to use an external probe connected to the available 20-pin JTAG connector to program and debug the board. Both JTAG and SWD are supported.
By default when using west debug ST-Link will be used with OpenOCD’s
SWD transport, but it is also possible to use JTAG with the Olimex ARM-USB-OCD-H
probe, for instance. For the latter, you should replace the file openocd.cfg
by openocd_olimex_jtag.cfg, located in the board’s support directory.
The blackmagicprobe can also be used to program the device.
Flashing
Here is an example for the Button application.
# From the root of the zephyr repository
west build -b olimex_stm32_h103 samples/basic/button
west flash
Debugging
You can debug an application in the usual way. Here is an example for the Hello World application.
# From the root of the zephyr repository
west build -b olimex_stm32_h103 samples/hello_world
west debug
