GTM32 Mini S WiFi Pinouts.

Post by Macflame » Tue Sep 17, 2019 7:10 pm

Does anyone know what the pinouts are for the wifi module connection on the GTM32 Mini S? I have looked on the schematics and it is not mentioned. I would like to attach a ESP82266 module to it.

Hello.

I think this topic has been raised before, but I don't remember the details.
If you don't find anything on the forum, it remains to read the MCU pinout, and test the connections with a multimeter.

But remember:
In order for new equipment to work with the printer, the firmware must support it. Otherwise, you will have a new decoration on the controller board. ;)
On the forum I help to use the rod, I don't give fish.

Thanks William. I had a look at this schematic before. It is for the Pro which has two rows of pins on the WiFi outlet. The Mini S has a single row. If it followed the same numbering convention it would be good.

Thanks kaktus. I did search for it and could not find a post either in hardware or the A30 forums.
As the firmware is now opensource it should be relatively simple to use the port. I should imagine all trace of anything related to this port has been erased since the release of Geetetech's WiFi module. lol

Eeeeee doooooon't. :D

One has nothing to do with the other.

Printer controllers are designed to be very versatile.
It happens that their functions are far ahead of the firmware.

It would take a long time to tell a story. :roll:

If I remember correctly, the Mini S controller has a small E180 printer.
Initially it was equipped with a wireless communication module.
However, due to some problems, the manufacturer decided to withdraw this equipment.
The low processing capacity in the company makes some things very time-consuming.
I understand that, but many users are upset about it. This is understandable to me. ;)

I started implanting ESP in my printer once. :D
GTM32 Pro vB.

Later I didn't have time to continue this project, and in addition I broke the PCB of the controller. :lol:

Now I have a new one. When I finish the modification I'm doing now, I'll go back to wireless communication in my controller.
This is a hardware solution. It also contains a trick, so it does not require any interference in the firmware. :roll:

Hi Macflame.
:mrgreen:

Thank you for the good word.
There is never too much of that. :D
