1.4 Delivery recommendations
Some verifications are needed before using the board for the first time to make sure that
nothing has been damaged during shipment and that no components are unplugged or lost.
When the board is extracted from its plastic bag, please check that no component remains
in the bag.
The main components to verify are:
1. The 8 MHz crystal (X1) which may have been removed from its socket by a shock.
2. The MicroSD card which may have been ejected from the connector CN14 (left side of
the board).
3. The dual interface EEPROM board (ANT7-M24LR-A) which may have been unplugged
from the connector CN2 (top right corner of the board).

The linear sensor is supported on the STM320518-EVAL evaluation board and connected to
four capacitive sensing channels (PB[11:14]) in group6 with an active shield connected to
two capacitive sensing channels (PC5 and PB0) in group3.
Note: The linear sensor is only fully functional when the STM320518-EVAL is powered on power
mode 1 (both VDD and VDDA are connected to a fixed 3.3 V). It is potentially necessary to
adjust the capacitor value of C14 and C15 and the firmware to adapt them to the voltage
range from 2 V to 3.6 V of VDD on power modes 2 and 3.
2.9 MicroSD card
The 2 GB (or more) MicroSD card connected to the SPI1 port of the STM32F051R8T6 is
available on the board. MicroSD card detection is managed by the standard IO port PB15.
2.10 Analog input
The two-pin header CN8 and 10 kohm potentiometer RV3 are connected to PC1 of the
STM32F051R8T6 as an analog input. A low-pass filter can be implemented by replacing
R60 and C36 with the correct resistor and capacitor values as required by the end-user
application.
2.11 LDR (light dependent resistor)
The VDDA is divided by the resistor bridge of the LDR VT9ON1 and 8.2 K resistor. It is
connected to PA1 (COM1_IN+/ADC IN1) as shown in Figure 4.

Note: The bi-directional voltage translator is implemented on the SPI MOSI signal between the
STM32F051R8T6 and the LCD to support the 3-wire serial interface of the
AM240320LGTNQW-01H LCD panel. The direction of this voltage translator is controlled by
IO PB2 (the IO PA7 acts as MOSI when PB2 is high or as MISO when PB2 is LOW).
2.14 RF E2PROM
An RF E2PROM module ANT7-M24LR-A is mounted on connector CN2 and is connected to
the I2C1 bus of the STM32F051R8T6. It shares the same I2C1 bus as the temperature
sensor U8 and DDC on the HDMI_Source connector CN4.
2.15 HDMI CEC
Two HDMI connectors CN3 and CN4 are available on the STM320518EVAL board.
● Connector CN3 is an HDMI sink connector with:
– DDC connected to I2C2 of the STM32F051R8T6
– HPD controlled by I/O PA11 through transistor T3
– CEC connected to PB10 through transistor T4
● Connector CN4 is an HDMI source connector with:
– DDC connected to I2C1 of the STM32F051R8T6 and shared with the temperature
sensor and RF E2PROM
– HPD controlled by I/O PA8
– CEC connected to PB10 through transistor T4
– 5V HDMI powered by power switch U5
Signals TDMS D+[0,1,2], TDMS_CLK+, TDMS D-[0,1,2] and TDMS_CLK are connected
together on these two HDMI connectors.
CEC injector mode can be enabled by reworking the PCB (for debugging purposes only):
● Remove resistors R63, R66, R23, R62, R68, R51 and R13.
● Close solder bridges SB4, SB5, SB6 and SB7.
Note: The I/O PA11 must be set in open-drain output mode by firmware for HPD signal control on
the HDMI sink connector CN3.

2.16 IR LED and IR receiver
The IR receiver TSOP34836 is connected to PB3 of the STM32F051R8T6 and a current
around 100 mA on the IR LED is driven by PB9 through transistors T1 and T2 on the board.
Note: The IR LED may be driven by PB9 directly with a 20 mA current when SB3 is closed and
R11 is removed.
2.17 Motor control
The STM320518-EVAL evaluation board supports both asynchronous and synchronous
three-phase brushless motor control via a 34-pin connector CN1. This connector provides
all required control and feedback signals to and from the motor power-driving board.
Available signals on this connector include emergency stop, motor speed, 3-phase motor
current, bus voltage, heatsink temperature coming from the motor driving board and six
channels of the PWM control signal going to the motor driving circuit.
Some PCB reworks are required for the motor control application to disconnect peripherals
that share IOs with the motor control connector. These IOs need to be connected to the
motor control connector.
● Remove resistors R89, R52, R19, R55, R32, R38, R42, R88, R83, R20, R36, R18 and
R50.
● Mount R25, R29, R30, R39, R4, R35, R37, R44, R22 and R41 with a 0 ohm resistor.
All resistors to be removed are marked in red while resistors to be soldered are marked in
green in Figure 5.
