MicroSD Port
The Zynq-7000 SoC SODIMM Carrier Board supports SDIO interface through SD0 interface of Zynq-7000 SoC PS. This
SD0 signals from SODIMM Edge connector is connected to Micro SD connector (J11) to support Micro SD storage.
The main power to Micro SD connector is 3.3V. This Micro SD connector (J11) is physically located at the bottom of
the board as shown below.
