OLIMEXINO-STM32
POWER SUPPLY CIRCUIT:
OLIMEXINO-STM32
can take power supply from:
–
external power supply (9-30) VDC.
–
+ 5V from USB
–
3.7 V Li-ion battery
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.
