Hardware layout and configuration
RF E2PROM
An RF E2PROM module ANT7-M24LR-A is mounted on connector CN2 and connected to
I2C1 bus of STM32F072VBT6, this bus shares the same I2C1 bus with the temperature
sensor U1 and DDC on HDMI_Source connector CN5.
2.17
HDMI CEC
Two HDMI connectors CN3 and CN5 are available on STM32072B-EVAL board.
•
•
The connector CN3 is HDMI sink connector with the following:
–
DDC connected to I2C2 of STM32F072VBT6
–
HPD controlled by IO PD15 through transistor T1
–
CEC connected to PB8 through transistor T2.
The connector CN5 is HDMI source connector with the following:
–
DDC connected to I2C1 of STM32F072VBT6 and shared with the temperature
sensor and RF E2PROM
–
HPD controlled by IO PE0
–
CEC connected to PB8 through the transistor T2
–
HDMI 5 V powered by power switch U3
The signals TDMS D+[0..2], TDMS_CLK+, TDMS D-[0..2], TDMS_CLK- on these two HDMI
connectors are connected together.
The CEC injector mode can be enabled by some PCB reworks for debugging purpose only:
•
Remove resistors R29, R31, R33, R42, R44, R48 and R51.
•
Close solder bridges SB7, SB8, SB9 and SB10.
Note:
the I/O PD15 must be set in open-drain output mode by firmware when working as an HPD
signal control on the HDMI sink connector CN3.
2.18
IR LED and IR receiver
The IR receiver TSOP34836 is connected to PC6 of STM32F072VBT6 and a current
around 100 mA on IR LED is driven by PB9 through the transistors T3 and T4 on the board.
Note:
the IR LED may be driven by PB9 directly with 20 mA current when SB24 is closed and
R138 is removed.
2.19
Motor control
STM32072B-EVAL evaluation board supports both asynchronous and synchronous threephase brushless motor control via a 34-pins connector CN1 that provides all the required
control and feedback signals to and from the motor power-driving board. The available
signals on this connector include emergency stop, motor speed, three phase motor
currents, bus voltage, heat sink temperature coming from the motor driving board and six
channels of PWM control signal going to the motor driving circuit.

when SB1 is closed.
Default setting: open
SB2
The special motor current sampling operation is enabled when SB2 is closed (PC8
connected to PF3). The IO pins PC8 and PF3 are disconnected and can be used by
the daughter board when SB2 is open.
Default setting: open
SB3
The pin14 of motor connector CN1 is connected to PC3 as MC_BusVoltage2 when
SB3 is closed. In such case R10 should be removed.
Default setting: open

when SB4 is closed.
Default setting: open
SB5
The pin17 of motor connector CN1 is connected to PA3 as MC_CurrentB2 when
SB5 is closed.
Default setting: open
Note:
the solder bridges SB4 and SB5 must not be closed at the same time. Also, SB1 and R10
must not be fitted at the same time.

A bidirectional voltage translator (U13) is implemented on SPI_MOSI signal between the
MCU and LCD in order to support the 3-wire serial interface required by several TFT-LCD
controllers. The direction of the voltage translator is controlled by IO PB2 (the IO PE15 is
working as MOSI when PB2 is high or as MISO when PB2 is LOW).

Daughter board extension connector CN7 and CN8
Two 52-pin male headers CN7 and CN8 can be used to connect with the daughter board or
with the standard wrapping board to STM32072B-EVAL evaluation board. All GPI/Os are
available on the connector. The space between these two connectors and position of power,
GND and RESET pin are defined as a standard, allowing the development of common
daughter boards for several evaluation boards. The standard width between CN7 pin1 and
CN8 pin1 is 2700mils (68.58mm). The standard was implemented on the majority of
evaluation boards.
