Most Beagles include a USB cable, providing a convenient way to provide both power to your Beagle and connectivity to your computer. If you provide your own, ensure it is of good quality.
Alternatively, your Beagle may have a barrel jack. The voltage should be 5V except for BeagleBoard-X15 and BeagleBone Blue which use 12V.
Note that BeagleBoard-X15 must always be powered by a 12V adapter with a barrel jack.
If you are using your Beagle with an SD (microSD) card, make sure it is inserted ahead of providing power. Most Beagles include programmed onboard flash and therefore do not require an SD card to be inserted.
You’ll see the power (PWR or ON) LED-lit steadily. Within a minute or so, you should see the other LEDs blinking in their default configurations. Consult the Quick Start Guide (QSG) or System Reference Manual (SRM) for your board to locate these LEDs.
- USR0 is typically configured at boot to blink in a heartbeat pattern
- USR1 is typically configured at boot to light during SD (microSD) card accesses
- USR2 is typically configured at boot to light during CPU activity
- USR3 is typically configured at boot to light during eMMC accesses
- USR4/WIFI is typically configured at boot to light with WiFi (client) network association (BeagleBone Blue and BeagleBone AI only)
