STMicroelectronics STM32F4VGT6 Cortex M4 MCU, up to 168Mhz with floating point unit (FPU), 192 KB RAM, 1024KB Flash
on-board stlinkv2 with SWD header (capeable of programming itself or a external MCU)
ob-board power regulator for the MCU (3V or 5V Input) 3v input possible at vdd?
1 x user push button
4 x LED (orange, green, blue, red)
4 x UART (UART1, UART2, UART4, UART6)
1 x SPI
3 x I2c (I2C1, I2c2, I2c3)
1 x PPM input
4 x ADC input, which one is used for bat voltage
97 x 66 mm PCB
4 x status LED (USB OTG, stlink red, stlink green, USB power)
CS43L22 audio codec with 3,5mm jack
LIS302DL MEMS 3 axis accelerometer

The Discovery has a male 100 pin (2x25pin on each side) pinout in 2,54mm on both sides of the board.

JP1 current consumption of the MCU can be measured here
CN3 set: stlinkv2 is connected to onboard MCU, unset: stlinkv2 is connected to SWD header to program external MCU

FLASH_MODE=DFU is set as default
stm32f4-discovery can be programmed in two different ways:

with the MCU native (embedded in rom) DFU USB bootloader over the micro usb ab connector
- required hardware: usb to micro and usb to mini usb cable
- required software: dfu_util tool (present
- put MCU in DFU mode: connect mini and usb to pc, connect pin BOOT0 with 3V, press reset button(LED LD7 should light up now), disconnect BOOT0 to 3V

with onboard stlinkv2 over SWD
- required hardware: usb to mini usb cable
- required software: st_flash and st_util
