The IrDA transceiver (TFDU6300) is not populated on STM3240G-EVAL evaluation board from version C08. The version of the board is written on sticker on the bottom side of the board (ex: MB786-C08).
Hardware layout and configuration Motor control The STM3240G-EVAL evaluation board enables a three-phase brushless motor control via a 34- pin connector (CN5), which provides all required control and feedback signals to and from the motor power-driving board. Available signals on this connector include emergency...
Hardware layout and configuration UM1461 2.10 Smartcard STMicroelectronics smartcard interface chip ST8024 is used on the STM3240G-EVAL board for asynchronous 3V and 5V smartcards. It performs all supply protection and control functions based on the connections with the STM32F407IGH6 listed in Table Table 9.
