Frequently Asked Questions

Do I need to solder headers before using the board?

Yes. The ESPresso Lite V2.0 is supplied with loose header pins that you must solder if you plan to mount it on a breadboard or enclosure. This gives you stable connections for programming and prototyping.

Which USB-to-Serial adapter should I use?

We recommend the UC00A adapter, as it matches the board’s 3.3 V logic. You can also use any USB-to-Serial adapter that supports 3.3 V TX/RX levels for programming and debugging.

How do I integrate with the espert.io cloud service?

After uploading your sketch with Wi-Fi credentials, open the Serial Monitor to retrieve the device’s unique ID. Register this ID at espert.io, then use the mobile or web app to configure data feeds, control pins, and monitor real-time statistics.
