Core 4 Discoveryboard STM32F407VGT6

this is one essential part for my triggermatrix5
i need a core pcb which is aviable in Europe, and uses the stm32F407VGT6 chip, which has 1MB ram…



i think there is a error - PB2 is not connected to the CORE MODULE FIXME

Building and BOM

parts off it is pick and place the other part is handsolder


the LCSC Parts are done with the Pick and place - so no need to order…

The Mouser parts that have to be soldered by hand - you have to order them on your own…:

copy following list into this


Order from Reichelt:
2x 2x25Pin Female 2,54mm Heades
1x 1x20Pin Male 2,54mm Header
1x 2x10Pin Male 2,54mm Header
5x 2x5Pin FeMale 2,54mm Header
4x 2x4Pin Female 2,54mm Header


1. If the Discoveryboard is a virgin-one then upload the bootloader via stm-utility
2. Upload the Bootloader
3. Disconnect and Reconnect the USB-Cable to your PC, then type “help” into the MIOS-Terminal, this should print out the actual Board-Configuration, if this happens then: 4. Type following commands:

set lcd_type 0x84
set lcd_num_x 26
set lcd_num_y 1
set lcd_width 128
set lcd_height 64

at least this has to be done when using this core for Triggermatrix5

To Do

It works! next variant will be, without Discoveryboard and the STM32F407vgt6 directly soldered to the board…
