CHAPTER 6 CONNECTORS AND PINOUT
6. Introduction to the chapter
In this chapter are presented the connectors that can be found on the board all together with their
pinout and notes about them. Jumpers functions are described. Notes and info on specific
peripherals are presented. Notes regarding the interfaces are given.

6.1 JTAG/SWD debug
The board can be debugged from the 20-pin JTAG connector either by a JTAG or a SWD
compatible debugger. Below is the table of the JTAG. This interface can be used with the Olimex's
OpenOCD debuggers.

6.2 SD/MMC slot
The microSD card slot is a standard 8pin connector.
We have tested a number of microSD cards on the STM32-H407 boards and all of them worked
fine regardless manufacturer or capacity. However, keep in mind that some of the lower quality
microSD cards might draw too much current from the slot which might cause power-state problems.
If you suspect the microSD card is causing problems please try using another one of better quality
for better results.
