ESP32-PICO-D4 external flash, no antenna

Postby jwktje » Mon Jun 22, 2020 3:25 pm

Hello Espressif!

I'm working on a prototype that utilizes a WROOM module but I want to make it smaller using a PICO.
My setup is based on Arduino. It needs large Flash storage but it doesn't need Wifi.

So what I'm wondering is;

1. Can I exclude an antenna with the PICO and simply not use Wifi/Bluetooth without issue?
2. Would I connect External Flash (like shown at this link) and would that work with the Arduino Core? ; viewtopic.php?t=6054
3. Would that external Flash work with SPIFFS like is used here? ; https://randomnerdtutorials.com/install ... duino-ide/

Thanks in advance for reading my questions. I hope you can clarify
