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 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 * VBUS LED * 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.
