1.2.2 Important Usage Notes

Note: The AM261x LaunchPad requires a 5V, 3A power supply to function. A 5V, 3A power supply is not included in the kit and must be ordered separately. The Belkin USB-C Wall Charger is known to work with the LaunchPad and supplied type-C cable. For more information on power requirements refer to Power Requirements. If there is an insufficient power input then the red LED (DS1) will glow. For more information on power status LEDs refer to Power Status LEDs.
Note: The AM261(U1) SoC on the LaunchPad can reach temperatures of around 54℃ during high power consumption use cases as per internal testing. This user guide statement is to alert users to this temperature condition.
AM261x
Note: External Power Supply or Power Accessory Requirements:
  • Nominal output voltage: 5VDC
  • Max output current: 3000mA
  • Power Delivery
Note: TI recommends using an external power supply or accessory which complies with applicable regional safety standards such as (by example) UL, CSA, VDE,CCC,PSE, etc.
