EEPROM

To fit the fast mode requirements, a 1 Mbit EEPROM, M24M01-HR, is directly connected to
the I2C2 bus of STM32F303VET6 by setting JP5 and JP6 jumpers, as shown in
Jumper
The EEPROM is in Write protection mode when JP8 is closed.
JP8
Default setting: Not fitted
JP5, JP6 See

CAN

The STM32303E-EVAL evaluation board supports one channel of a CAN2.0A/B compliant
bus communication based on the 3.3V CAN transceiver. The high-speed mode, standby
mode and slope control mode are available and can be selected by setting JP4.
Jumper
The CAN transceiver is working in standby mode when JP4
is set as shown to the right:
The CAN transceiver is working in high-speed mode when
JP4
JP4 is set as shown to the right: (default setting)
The CAN transceiver is working in slope control mode
when JP4 is open.
The CAN terminal resistor is enabled when JP3 is fitted.
JP3
Default setting: Not fitted
CAN will work properly when VDD > 3 V.

IR LED and IR receiver

The IR receiver, TSOP34836, is connected to PA9 of STM32F303VET6 and the IR LED is
driven by PB9 through transistors T4 and T5 on the board. The IR receiver depends on
JP18 jumper setting, as shown in
The IR LED may be driven by PB9 directly when SB19 is closed and R281 is removed.

High brightness LED

An amber high brightness LED and its power control circuits are on the STM32303E-EVAL
board. The brightness can be adjusted by the PWM signal from STM32F303VET6 through
PE13. The current on the LED can be monitored by the STM32F303 thanks to the voltage
measured on PD14, which corresponds to current through R261 (10 ohm).
