Yes, just like the other modules but smaller. They all have three hardware serial ports that you can choose between.

And if you know, does this TTGO support also cryptographic hardware during wifi connection like thos espressif ones?

Ah but wait!! jkingdon , I just read right now about this ttgo.... it looks like to be the relative module using the ESP32-PICO-D4 so I could use that just like as a module , right?

Hi again jkindgon !!

I understand, so that means I'd should go for ESP32-WROVER-IE and its relative ESP32-DevKitC V4 so that would be dual core and looking at peripheral schematics there are those pins TXD0 and RXD0 that can be connected to a UART port of my device.... right?

Thanks again ...

Hello jkingdon

thank you for your reply!! ... :-)
I went looking on espressif's products about modules and I found that ESP32-PICO-D4 you suggested is a SoC instead a module which should be easier to manage than a SoC since it can just be connected to the UART of the device.... right?
In this ...

Hello everyone!!! :-)

I am going to play with WiFi connections with a device and I was thinking to use an ESP32..... in a sample article I read they were using ESP-01 module by AI-Thinker with those pins for firmware upgrade... Could you suggest me which one of those ESP32 series , which are newer ...
