Waveshare Core405R Stm32F405Rgt6 Mcu Core Board



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

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

What’s On Board

STM32F405RGT6: the high performance STM32 MCU which features:

Core: Cortex-M4 32-bit RISC
Operating Frequency: 168MHz, 210 DMIPS/1.25 DMIPS/MHz
Operating Voltage: 1.8V-3.6V
Package: LQFP64
Memories: 1MB Flash, 192+4kB SRAM
MCU communication Interfaces:

3 x SPI, 4 x USART, 2 x UART, 2 x I2S, 3 x I2C, 1 x SDIO, 2 x CAN
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

AMS1117-3.3: 3.3V voltage regulator
MIC2075-2: onboard USB power management device
Power supply switch, powered from 5Vin or USB connection
Boot mode selection, for configuring BOOT0 pin
Power indicator
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

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.
