With the 2 LDO's, one is always on to power the ESP32 in deepsleep and the 2nd shuts off in deepsleep to save power. 1 stemma connector is connected to 1 LDO that's always on and the other is attached to the 2nd LDO to shuts off in deepsleep. This allows you to attach adafruit/sparkfun sensor boards and not have them pull power in deepsleep if its not needed to be on 24/7.

Additionally there are 2 versions of an i2c extender board which allows attaching adafruit or some sparkfun sensor boards for a sleek compact data logging package. 1 extender holds 1 adafruit sensor, the XL holds 2 adafruit sensors.

Well thought out design for data logging applications

Great design and fast shipping. Will definitely buy again. Haven't had any direct communication with the seller because there was no need. But based on the quality of design and fast shipping, I wouldn't expect any less.

Excellent product with even better support

I previously purchased the Bee S3 for a low energy product and was pleasantly surprised at the customer service. The support was quick and had me up and running answering my all my questions. When time came to upgrade to a more capable board I went back and ordered this ESP32 with a Data Logger for my project. The product was shipped promptly and the boards are quite sweet!

I totally recommend grabbing a Bee series controller for your next project, especially if your project has low power needs!
