They support multi-voltage fixed outputs (3.3V, 5V, 9V, 12V) via jumper selection and feature overtemperature protection that automatically reduces output current to prevent damage during demanding flight conditions.\u003c\/p\u003e\n\u003ch4\u003eQ: How do I set the output voltage on these DC-DC converter modules?\u003c\/h4\u003e\n\u003cp\u003eA: The factory default output is fixed at 5V. You can change the output by configuring the onboard voltage jumpers to select 3.3V, 5V, 9V, or 12V fixed outputs. Alternatively, you can use the adjustable voltage mode to set a custom voltage within the specified range. Specific jumper combinations also allow intermediate voltages (e.g., shorting the 3.3V and 5V jumpers simultaneously on the step-up module gives ~7.2V output).\u003c\/p\u003e\n\u003ch4\u003eQ: Is there reverse polarity protection?\u003c\/h4\u003e\n\u003cp\u003eA: No — neither module includes reverse polarity protection.
