Here is a list of examples on how to wire components, power supplies, connectors, sensors, etc to the CM-SAMA5D3x to create your own Linux embedded board. Click on the image of the device you want to add.

If you want to get more details, you can see the schematic file of the base board.

• Power supply

  CM-SAMA5D34 needs a single line 3.3 volt DC power supply which can be provided in any combination on the following pins: Signal Name Type Pin # Description VDD33V_IN Power J3-Pin59, J3-P60 Main power supply. Typical voltage 3.3V. GND Power J2-Pin1, Pin33, Pin59 J3-Pin2, Pin25 Common ground.

• Reset schematic

  NRST is the Board reset Pin, low voltage can enable the Reset. Signal Name Type Pin # Description NRST I J1-Pin18 Low voltage can enable the Reset

• RTC Backup battery

  Applying 3 Volt DC on J3-Pin2(GND) and J3-Pin58 (VBAT +3VDC) it is possible to mantaint the RTC (Real Time Clock) active when the power supply if off. This will mantain the system clock up to 6 months with no power using a small CR2032 Lithium battery. A bigger battery can be used to extend the time duration. Signal Name Type Pin # Description VSBAT Power J3-Pin58 RTC Power In GND Power J3-Pin2 Common ground.
