Definite clarification of using external lipo power supply

I spent the evening soldering the pins to my EZSBC ESP32 dev board and I'm ready to start testing my board and TFT combo for a project I'm working on but I'm afraid to add power to it. Can I please get a definite yes or no on wether I can power it straight from a 3.7v lipo for external power? Is there any product available that can limit my battery down to appropriate voltage?

Here is a link to my dev module.

If the board has a 5v input and a LDO with a small threshold voltage then yes. But don't connect to 3.3v directly.
