→Power Distribution
=== External Power Sources ===
There are two main sources to supply power to the CW308:
* DC-input power jack (2.1mm barrel jack, center positive, 5.0V)
* ChipWhisperer 20-pin connector (5.0V and 3.3V).
Note you can use the DC-input power jack alongside the ChipWhisperer power supply. The CW308 can switch the DC-power on/off, allowing the ChipWhisperer to still control the target power.
=== On-Board LDOs ===
There are five LDOs on-board the CW308. While they are mostly rated for 800mA, the board does not have sufficient thermal dissipation to operate at these conditions.
Four of the LDOs have fixed voltage settings: 1.2V, 1.8V, 2.5V, and 3.3V. The fifth LDO is adjustable, and is especially useful if you need to either (a) overcome the voltage drop of a shunt, or (b) feed a power supply into a device to turn off an internal regulator.
