2.1.4 SD Card Interface
The CC35xxE supports SD/MMC peripheral to write to SD memory cards. The LP-EM-CC35X1 features a
footprint for an SD card slot (J3) on the back of the board.
To use the SD slot, the 693071010811 SD Slot must be assembled on J3 footprint on the back (see Figure 2-8),
and some resistors need to have the configuration changed, (see Figure 2-9).
Figure 2-8. SD Card Slot
On the front side of the board, there are some resistors that need to be changed or added. See Figure 2-9.
• R34 footprint needs to have a 0 ohm resistor (0402) assembled.
• R29-R33, R67 need to be placed on the right 2 solder pads instead of the default left two pads.
