5.10 MicroSD
card
The 2-Gbyte (or more) microSD card connected to SDMMC port of STM32F479NIH6 is
available on the board. MicroSD card detection is managed by MFX GPIO15.
5.11 RF-EEPROM
RF-EEPROM daughterboard ANT7-M24LR-A is mounted on CN2 to STM32F479NIH6 via
I2C1 bus.
The RF-EEPROM can be accessed by the microcontroller via the I2C1 bus or by
radio frequency (RF) using a 13.56 MHz reader (for example, CR95HF).
