In this article you can find some additional information to the SODIMM pins of the Colibri modules.
Please note that this list is not complete and discusses just a few pins
| Signal | Name | Recommendation |
|---|---|---|
| 3.3V, GND | Digital Supply | Make sure all 3.3V and GND pins are connected and you use decouple capacities. |
| VCC_BATT | Supply for internal RTC | Make sure this pin is powered even if you don't use the internal RTC |
| VSS_AUDIO, AVDD_AUDIO | Analog Supply | Make sure you supply this even if you don't use any of the analog functions. If you use analog function, we recommend to use an additional regulator to get a clean analog supply. |
| nCSx | Chip Selects | Pull this pins high if you use the external memory bus |
