Step 15Add The Voltage Regulators
The Propeller runs at 3.3V, but Propeller Platform also includes a 5V regulator to provide 5V to other modules.
VR1: the 5V regulator. It's an ON Semi (part # MC33269T-5.0G). Compared to the 3.3V regulator, it has a square tab that's a bit thinner. The black box doesn't have a little notch, either.
VR2: the 3.3V regulator. It's an ST (part # LD1117V33). It has a thicker tab with the tab corners trimmed off.
You can also use a bit of extra solder to connect the tab to the board. This will help the regulators sink more heat.
