PROTOTYPE AREA CONNECTOR DESCRIPTION:
STM32-P103 can take power from two sources:
-
-
The board power consumption is: about 50 mA with all peripherials and
MCU running at full speed, there are different power saving modes which
may put STM32F103RBT6 in power sleep mode and in these modes the
consumption of the MCU is only few micro ampers.
STM32-P103 reset circuit is made with RC group R8 - 10K and C28 -
100nF.
Although on the schematic is made provision for external reset IC such is
not necessary as STM32 have build-in brown out detector. Manual reset is
possible by the RESET button.
Quartz crystal 8Mhz is connected to STM32F103RBT6. Internal PLL circuit
can multiply this frequency up to 72Mhz.
32.768 KHz quartz crystal is connected to STM32F103RBT6 for it’s internal
Real Time Clock.
Please have look at board layout picture, all signals are on the silkscreen.
USB connector where 5V power supply is applied by USB host
PWR jack where +6-9VDC or 5-9V AC may be applied, as there is bridge
rectifier the polarity doesn’t matter
