Version 3 has arrived! It looks just like version 2 on the outside, but it has a few big changes. These changes has made it more robust and made the display much more reliable.

The new version now uses a Esp32-S3 DevKit from Expressif. This DevKit has all of the I/O pins I needed without the I2C port expansion chips. The CPU board uses fewer SMD components overall as well. I replaces the SMD resistors and transistors for driving the digits with through hole components.

The changes to the code includes 

• Migrated to version 5.4 IDF build tool.
• Made the menus even more object oriented
• Expanded the JSON messaging
• Added rudimentary Home-Assistant support
• Integrated support for the Govee H5100 bluetooth temperature sensors.

The display board has not changed at all.
