Hello! Could you please suggest which RTC (Real-Time Clock) I should use with the ESP32? Which are widely used, Chea,p, and can be easily programmed with MicroPython or have readily available libraries? I'm planning to design a PCB for this, so I'm not looking for an RTC module.

Hello Everyone!
Which HMI LCD have you used, or which one would you recommend that is compatible with the ESP32? I want to create a GUI for it.
Some options I know are
1)Nextion 3.5" HMI LCD
2)TJC 3.5" HMI
3)LVGL
Note: I have only 3 spare pins, so I need LCD support via I2C or UART communication. I ...
