While writing the articles about the ESP32 weather station, I came across a small problem that sounds quite simple at first, but turned out to be a bit more complicated than I thought. How do you take a screenshot of an LVGL screen running on an ESP32 microcontroller?

The ESP32 weather station is now over a year old. So it's high time for an update. I have therefore spent the last few weeks developing a completely improved version of the weather station. I would like to present the changes to you in this article.

The FireBeetle 2 ESP32-C6 board from DFROBOT is very affordable and integrates not only the ESP32-C6 but also a charge controller for charging a lithium-ion battery and monitoring battery voltage. In this article, I'll show you how to build a cost-effective sensor for the weather station using this board.

Makerfabs offers two new 7-inch displays with IPS panel and ESP32-S3 microcontroller. After my review, I realised that only one version actually has an IPS panel. The lower resolution display uses a TN panel and is similar to the Sunton 7-inch display.
