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 - |
