STMicro Discovery-F4 Baseboard, 4-layer PCB and two 2x25 Sockets

STM32-F4B1 breakout board for the STMicro Discovery F4 board (STM32F407G-DISC1) with STM32F407VGT6 microcontroller
Ten GPIO port headers providing 8 data bits and 3V/5V power.
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.
Bare PCB with two 2x25 DIL sockets provided for Discovery-F4 headers.
All 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).

The STM32-F4B1 breakout board provides port connectors, USART, I2C, and SPI expansion headers to make it easy to prototype with the ST Micro Discovery F4 board.

The Discovery F4 module includes a STM32F407VGT6 microcontroller with 1024k program flash, 192k RAM, and a floating-point/DSP unit in a LQFP100 package. An on-board ST-LINK/V2 programmer allows code to be loaded and debugged via PC USB port. Accelerometer, microphone, and DAC peripherals are provided. Power comes from the Discovery board USB connector or a barrel connector.

Ten 2x8 headers are used for GPIO port expansion. Each header has 8 data bits, 3V power, 5V power, ground, and 5 uncommitted pins for customization.

Two ComBoard module footprints allow RS232 or RS485 serial interfaces to be added and quickly changed. Two ASPICE module footprints allow I2C, SPI or analog modules to be added. Other footprints include: One 4-pin USART connector. One 4-pin CAN bus connector. SD card with activity LED and power switch circuitry. RTC CR2032 battery holder.

PCB-STM32-F4B1 is an unpopulated board and only the 2x25 sockets for the Discovery module are included (no other parts provided). The BOM (bill of materials) and schematic diagram are available below to construct the board. Soldering is required and prior experience with electronic assembly is recommended. Thru-hole construction allows for easy assembly, maintenance, and modification. Optional JTAG interface and SD-card circuitry use SMT parts.
