Is it possible to replace the WIFI module?

yes, just run M997 S1 after the new module is soldered in place and the duet will write the firmware to the new wifi module

kotuo

Thanks for the reply.
If I run M997 S1, will the firmware be written automatically?

(if not clear you need to use a wifi module with the same physical pinout or make an adapter, but pretty much all esp8266 modules will work with the firmware)

yes, provided the wifiserver.bin file is on the sd card in the /sys folder. which it normally is when installing/updating the firmware from the .zip file from a major release.

Thanks for the reply.
I will create an adapter and transfer it to ESPesp8266.

you can convert you duet wifi to a duet ethernet that way

kotuo

I've never used it, but I think it can be used.
But I would like to use it for one of the experimental machines in Iot development.
I think an Ethernet connection is the last resort.
But I didn't know there was a module for Ethernet connectivity.
Thank you very much.

Only an indirect info for you maybe of interest for all options:

You could also take one of the duet3-family boards to connect a raspi/raspberry-pi to it directly so that you have all options...

The new duet3mini should be released Q1/2021 as far as I undertstood here https://forum.duet3d.com/topic/17409/duet-3-mini-5-initial-announcement/70?_=1605710723339

Sorry to only be able to help indirectly, but maybe of some use for you

kotuo

@LB Thanks for the reply.
I did not know that there is an option to use Duet3.
I consider it one of the solutions.

As of firmware 3.2 you can also use Raspberry Pi with existing Duet 2 Wifi, replacing the Wifi with SPI connection to Raspberry Pi, but it it only available as beta version still.

@bearer Thanks for the reply.
I'll take the time to read it

Welcome to the forum!

You can replace the ESP-12S by ESP-12F. The ESP-12F has some extra pins at the back of the module but they do not need to be connected to anything.

The WiFi version of the forthcoming Duet 3 Mini uses the WROOM-02U module. I have not found a TELEC certification document for this module, but the version with internal antenna (WROOM-02D) is TELEC-certified.

@dc42 Thank you for your reply.
This is my first post, so I didn't expect to get many replies and responses from the admins.
I'm glad to get so many responses.
Are there any past threads on how to switch the wifi module on the ESP-12f?
I would like to know if there are any.　
But I'm confused.
1, reload the wifi module
2, Duet 2 Ethernet SBC
3, wait and buy a duet 3 mini
Three fascinating answers are running through my head.
Oh my God!（＾ω＾）

By the way, you're not the first to request this.

Are there any past threads on how to switch the wifi module on the ESP-12f?

@Phaedrux Thank you for your reply

Another option if you don't want to void the warranty by replacing components or cannot solder well enough for a replacement: use a small wifi router like the GL.inet AR150. I did this successfully with the old duet 0.6 board and the duet 3 mini beta board which came with ethernet (my workbench still does not have ethernet). These routers can be configured as bridges where the router only connects to the wifi to pass through the connected devices.

The only Duet2 sold in Japan is the Duet 2Wif (clone).

Just out of curiosity, can't you buy an Ethernet Duet directly from the UK?

As an aside, we've signed a significant trade deal between the two countries. If I were part of the Duet team, I'd be looking seriously at this opportunity.

kotuo

@oliof Sorry for the delay in replying.
Thank you for your reply.
Thank you for telling me the safest and easiest way.
I'm also new to Duet, so I thought this was the best way.

oliof

@kuoto your way certainly is an option for those with the tools and ability!

kotuo

@deckingman Sorry for the delay in replying.
Thank you for your reply.
I'm also new to Duet, so I'd like to have a real one, if possible.
But I think the only problem is the cost of importing it and how many days it will take for delivery.
