1.1 Power
supply
The STEVAL-IHM022V1 demonstration board is designed to be powered by a 5 V DC power
supply and to be protected from incorrect power plug-in events by a PolyZen U5. The
demonstration board can be configured to use any of following three power sources:
●
5 V DC power adapter connected to power jack CON12 (DC5V on the silk screen).
Alternatively, 5 V DC can be provided through 2-way screw connector CON13 (aux
DC5V on the silk screen) when using a generic DC power supply
●
5 V DC power with 500 mA limit from the type-B USB connector CON11 (USB B on the
silkscreen)
●
5 V DC power from daughterboard extension connectors CON1 and CON3
The power supply is configured by setting jumpers JP9, JP10, JP11 and JP12 as described
in
The D5 LED is lit when the demonstration board is powered correctly.
1.2 Boot
options
The STEVAL-IHM022V1 demonstration board can be booted from:
●
embedded user Flash
●
embedded SRAM for debugging
●
system memory with boot loader for ISP
The boot option is configured by setting switch BOOT0 and BOOT1 as described in
Table 1.

place a jumper on JP9 only (default setting).
For power supply from the daughterboard extension connectors
CON1 and
CON3, place a jumper on JP10 only.
For power supply from USB connector CON11, place a jumper on JP11 only.
For power supply from power supply jack CON12 to both the STEVAL-
IHM022V1 and the daughterboard connected on CON1 and CON3, place
jumpers on JP9 and JP10 as shown (the daughterboard must not have its own
power supply connected).
