ESP32

[ManS-H]

Which brand ESP32 can I best use as a replacement for ESP-8266 There are several brands and type numbers. Which one do the developers of ESPEasy recommend?

Depends on whether you need some specific form factor.
If you need to replace those tiny ESP-01 boards, LilyGo does have a "form factor compatible" T-01C3 which is using an ESP32-C3

N.B. I use "ESP32-classic" to refer to the good old ESP32, thus no -C, -S or other variant.
Not sure if "classic" is used anywhere else, so no need to look for "classic" on sites like Ali Express

If you have the option, I would suggest to go for boards with 16M of flash.
The ESP32-S3 is by far the most capable as it has lots of IO and is quite fast.


The ESP32-C3 can be had in a very tiny form factor and still has all its usable pins made available.

The ESP32-C2 is used in some of-the-shelve units, so that's why I added support for it.
But I wouldn't use it for anything else as it is a limited chip in lots of ways.

The ESP32-C6 does have WiFi-6 support, but other than that it isn't (yet) much different from the -C3.
It might be useful later when we add "threads", or Zigbee support. But I'm not convinced it is really usable with both Zigbee and WiFi at the same time.

ESP32-S2 is a bit of a strange "inbetween" chip.
It does work fine, it may feel more 'snappy' compared to the other ESP32-variants (except -S3) and it does have more GPIO pins compared to other boards (except the -S3 which has more pins)
But it feels like it is a bit odd in several interfaces.
Also there are some purple boards sold with the S2 which are really a hit-or-miss regarding WiFi stability.
IMHO, ESP32-S2 is not worth it anymore now we have the -S3.


And last-but-not-least... the "ESP32-classic" is still a viable option.
Just make sure to go for 16M flash as it allows to install the "max" builds which contain all plugins and controllers.

Thanks for the explanation TD-er.
Where in this line-up can ESP32-Cam and ESP32 DEVKITV1 (NodeMCU-ESP32 )be placed?

[TD-er]

Both use ESP32-classic.
And probably also 4MB flash size.


I think these are now the better choice: ESP32-S3 16M flash/8MB PSRAM ("original")
