SPI Display Array (Six 0.96" LCD Displays)

I am thinking of buying one of these SPI Display Arrays:
https://www.tindie.com/products/savagee ... lay-array/
It's basically six 0.96" 160x80 ST7735 displays on one board, with common SPI bus and LED backlight connections.
Each display has a separate CS pin so you can choose the desired display to load.
Questions:
1. Would the built-in ST7735 support work with this board?
2. Can the six CS lines be controlled manually on separate ESP-32 pins?
3. Does anyone see any problems that I'm overlooking?
Thanks,
Eric

Yes, it should be possible to use it simply dedicating a separate CS signal for each display and enabling "manually" one at the time.

That's what I thought; thanks for the confirmation.
A beginner question, please - the help file mentions that there are different types of ST7735 OLEDs and to try the different types in the configuration UI. Is that in the flashing software tool or built into Annex32 itself?
One last question (for now at least) - do you have a recommendation for a reliable ESP-32 board? Since I won't need the built-in OLED on the board I'm currently using, I'd like to find one that's smaller and less expensive, if possible.
Thanks again for all your help.
Regards,
Eric

For the ESP32, the ST7735 is configurable inside the config page
You can simply find this information in the help

About the modules, I think the easiest to use are the WEMOS D1-mini or the classic Devkit
