MicroSD - J21[edit | edit source]

J21 is a microSD memory card connector. It is connected to the BORA Xpress SOM through a bidirectional 1.8V/3.3V voltage-level translator mounted on the BORA Xpress EVB. Level shifter is required because MIO signals are 1.8V. The following table reports the pinout of the connector:

Pin# Pin name Function Notes
1 PS_SD0_DAT2 - -
2 PS_SD0_DAT3 - -
3 PS_SD0_CMD - -
4 3.3V - -
5 PS_SD0_CLK - -
6, 9, 10, 11, 12 DGND - -
7 PS_SD0_DAT0 - -
8 PS_SD0_DAT1 - -
3.3V - Pull up to 3.3V with 10K Ohm -
