Product Description
STM32 STM32F405RGT6 MCU core board, full IO expander, JTAG/SWD debug interface

Overview
Core405R is an STM32 MCU core board designed for STM32F405RGT6, 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

- Reset button
- 8M crystal
- 32.768K crystal, for internal RTC with calibration
- JTAG/SWD interface: for debugging/programming
- USB connector, used for establishing USB communication between PC and the STM32 development board
- MCU pins expander, VCC, GND and all the I/O pins are accessible on expansion connectors for further expansion
- 5Vin pinheader, 5V power supply is required when using USB HOST/OTG
-
USB jumper
- short the jumper when using USB
- open the jumper to disconnect from related I/O port
-
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.
Core405R provides JTAG/SWD debugging interface, yet does NOT integrate any debugging function, a debugger is required.
