Power Supply
The MCBSTM32F200 Board can be powered through two different connectors:
- USBFS or USBHS: The board is supplied automatically with 5 V when connected to a PC through a USB A to Micro B cable. The STM32 microcontroller can use the USB interface as a USB device.
- PWR: Power may also be supplied by an 8-12 VDC external power supply which must be capable of providing up to 500mA of current. IC2 reduces and regulates this to 5.0VDC.
The voltage regulators IC3 and IC4 generate 3.3 Volts DC to supply all components on the board. When jumper J1 is in the BAT position, the CR1220 lithium battery supplies power to the CPU to maintain the real-time clock.
The PWR connection uses a standard 5.5mm barrel plug with a 2.5mm inner diameter. The center conductor provides positive voltage.
