2.2 Hardware Setup

WARNING

Turning on the power supply lights the high-brightness LEDs on the board, starting with blue and cycling automatically through the color range.

Protective eyewear is recommended!

To set up the hardware:

  • Plug the DC connector of the AC adapter into J3 or connect a lab power supply set to 3.6 V to 6 V between J1 and J2.
  • Plug the mains connector of the AC adapter into the mains supply.
  • Turn on the mains supply.

CAUTION

Use of a poorly regulated AC adapter may generate overvoltage conditions exceeding the absolute maximum ratings of some of the components used. It is recommended that only well-regulated (5 V ± 0.5 V) adapters be used with this EVM.

CAUTION

AC adapters with long cables (approximately 1 m or longer) can exhibit significant stray capacitance that may interact with the EVM input capacitance and cause ringing when hot plugged. To avoid such potentially damaging overvoltage conditions, first plug the adapter DC plug into J3, then connect the AC adapter to the mains.
