POWER SUPPLY CIRCUIT:
OLIMEXINO-STM32
can be powered from:
–
external power supply (9-30) VDC.
–
+ 5V from USB
–
3.7 V Li-ion battery
–
JTAG/SWD programmer/debugger
The programmed board power consumption is about 50 mA with all peripherals enabled.
RESET CIRCUIT:
OLIMEXINO-STM32
reset circuit includes D6 (1N4148), R28 (10kΩ), R29 (330Ω), C31
(100nF), STM32F103RBT6 pin 7 (NRST) and RESET button.
CLOCK CIRCUIT:
Quartz crystal
Q1
8 MHz is connected to STM32F103RBT6 pin 5 (PD0/OSC_IN) and pin 6
(PD1/OSC_OUT).
Quartz crystal
Q2
32.768 kHz is connected to STM32F103RBT6 pin 3 (PC14/OSC32_IN)
and pin 4 (PC15/OSC32_OUT).
JUMPER DESCRIPTION:
Note that all jumpers on the board are SMD type. You will need to solder/unsoder/cut them in
order to reconfigure them.
LED1_E
This jumper, when is closed, enables LED1.
Default state is closed.
LED2_E
This jumper, when is closed, enables LED2.
Default state is closed.
D23_E
This jumper, when is closed, connects STM32F103RBT6 pin (PC15/OSC32_OUT) –
signal D23 to EXT pin 1, and when is opened, D23 is not connected to EXT.
Default state is opened.
R-T
This jumper, when is closed, connects TRST and RESET, and when is opened, TRST
and RESET are separated.
Default state is opened.
