Temperature sensor

2
One I C interface temperature sensor STLM75 (–55°C to +125°C) connected to I
STM32F103Z is available on the board.
2.13

Analog input

Three BNC connectors CN2,CN3 and CN5 are connected to PC3, PC2 and PC1 of the
STM32F103Z as external analog input. The 50 ohm terminal resistor can be enabled by
closing the solder bridge JP23, JP24 and JP25 for each BNC connector. A low pass filter
can be implemented for each BNC connector CN5, CN3 and CN2 by replacing R5 and C22,
R4 and C13, R3 and C9 with the right resistor and capacitor values, depending on the
requirements of your application.
2.14

IrDA

IrDA communication is supported by the IrDA transceiver U13 connected to USART3 of
STM32F103Z. The IrDA transceiver can be enabled or disabled by setting JP21.

USB

STM3210E-EVAL evaluation board support USB2.0 compliant full speed communication via
a USB type B connector (CN14). The evaluation board can be powered by this USB
connection at 5V DC with 500mA current limitation. USB disconnection simulation can be
implemented by disconnecting 1.5K pull-up register from USB+ line. The USB disconnection
simulation feature is enabled by setting JP14.

IrDA related jumpers
JP21 is used to shutdown the IrDA transceiver.
IrDA is enabled when JP21 is fitted while IrDA is disabled when JP21 is not
fitted. Default setting: fitted
IrDA_RX is enabled when JP22 is closed. The IO pin PC11 is used as the data
line 3 of the MicroSD card when JP22 is open. Default setting: not fitted
USB related jumpers
The USB 1.5K pull-up register is always connected to USB+
line when JP14 is set as shown.
The USB 1.5K pull-up register can be disconnected by software
from USB+ line when JP14 is set as shown. In this case, the
USB connect/disconnect feature is managed by standard IO
port PB14 (default setting).
