PCB-STM32-F4B1 Development baseboard for the STMicro Discovery-F4 module (STMicro part STM32F4DISCOVERY) PCB Rev 1.00 shown. PCB Rev 1.20 has on-board RS232 drivers. Part Number: PCB-STM32-F4B1 (unpopulated PCB with Discovery module sockets, no other parts) STM32-F4B1 (assembled board, not presently available) Features STM32-F4B1 is a breakout board for the STMicro Discovery F4 board (with STM32F407VGT6 microcontroller, 1024k program flash, 192k RAM, DSP, and floating point instructions). Bare PCB with two 2x25 DIL sockets provided for Discovery-F4 module headers. No other parts are provided. BOM and schematic are available for download. Ten GPIO port headers provide 8 data bits and 3V/5V power on each. Two ComBoard footprints provide USART interfaces. Two ASPICE board footprints provide I2C, and SPI expansion signals on 14-pin headers. SD card connector footprint provided. Mostly thru-hole construction allows for easy assembly. 4-layer, FR4 glass-epoxy PCB, 1oz/ft2 copper. Soldermask & silkscreen. Lead free and RoHS compatible. 6.30 x 6.30in (160 x 160mm).
