Overview

Core205R is an STM32 MCU core board designed for STM32F205RBT6, supports further expansion. It is ideal for starting application development with STM32F family.

• Minimal ready-to-run system, integrates clock circuit, USB control circuit, USB connector, etc.
• All the I/O ports are accessible on the pin headers
• JTAG/SWD programming/debugging interface
• 2.54mm header pitch, allowed to be plugged-in your application board

     • 1 x USB 2.0 HS/FS device/host/OTG controller with dedicated DMA, on-chip full-speed PHY
     • 1 x USB HS ULPI (external PHY required)
   • AD & DA converters: 3 x AD (12-bit, 1μs, shares 16 channels); 2 x DA (12-bit)
   • Debugging/Programming: supports JTAG/SWD (serial wire debug) interfaces, supports IAP
2. AMS1117-3.3: 3.3V voltage regulator
3. MIC2075-2: onboard USB power management device
4. Power supply switch, powered from 5Vin or USB connection
5. Boot mode selection, for configuring BOOT0 pin
6. Power indicator
7. VBUS LED
8. Reset button
9. 25M crystal
10. 32.768K crystal, for internal RTC with calibration
11. JTAG/SWD interface: for debugging/programming
12. USB connector, used for establishing USB communication between PC and the STM32 development board
13. MCU pins expander, VCC, GND and all the I/O pins are accessible on expansion connectors for further expansion
14. 5Vin pinheader, 5V power supply is required when using USB HOST/OTG
15. USB jumper
    • short the jumper when using USB
    • open the jumper to disconnect from related I/O port
16. VBAT selection jumper
    • short the jumper to use system power supply
    • open the jumper to connect the VBAT to external power, such as battery

Note:
Mother board or programmer/debugger in the photo is NOT included in the price.
Core205R provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
