Note:
1
Some 0 ohm resistors have to be removed or soldered to enable motor control application
except the solder bridges configurations mentioned above:
– R34, R58 & R51 to be removed
– R66, R204 & R205 to be soldered
2
MicroSD card must be removed from CN6 for motor control application.
2.10 Smartcard
STMicroelectronics smartcard interface chip ST8024 is used on STM3240G-EVAL board for
asynchronous 3V and 5V smartcards. It performs all supply protection and control functions
based on the connections with STM32F407IGH6 listed in
