Can it be used with an Arduino platform? What can be done with this module?
I'm not a very good connoisseur, but I would like to try to use this module somehow.
I found, I think, the closest board in appearance to the one I have. I followed this guy: https://www.youtube.com/watch?v=FbHiz3O6JYk&ab_channel=NematicsLab , but I can't program the board. It tells me that I either have an error on the COM port (although I can select it in the IDE) , or that the selected board is not connected. So I think I can't access this module.
I apologize if this post is inappropriate for this forum.
I see a MakerBase label and I'm guessing it's a Wi-Fi module for an Ultimaker 3D printer maybe. If so, they probably have some firmware uploaded. To reprogram it I guess you'll need some extra hardware.
Hi,
Your module looks like this:
This module uses an ESP8266-12S that can be programmed with the Arduino IDE as long as it uses a USB/TTL 3.3V interface .
It's a very good tutorial, except that I haven't seen any pictures with an ESP board (there are many ESP boards on the internet and I don't know much about them), there is a lot of good information there. I noticed that guy's module has an 'Enable' pin which is required, but my module has a "Not connected" pin. Maybe this thing really matters.
Hi,
researching more about this module of yours, I found a documentation of it with a schematic at:
" MKS-WIFI/hardware at master · makerbase-mks/MKS-WIFI · GitHub "
But the schematic does not show the resistors that exist in the module.
I believe that these resistors are connected as in my schematic on the side.
I could not identify where it goes connected R1.
And there is also a change in pin naming.
ESP GPIO00 is connected to module I01 and ESP GPIO04 is connected to module pin I02.
It is also unclear the value of VCC, if it is 5V or if it is 3.3V.
It looks like there is a regulator in the module. (red circle)
If this regulator is an LM1117 or similar and its input is connected to the VCC pin, then most likely the module power supply is 5V.
In the drawings I posted there is a schematic that I use in ESP with FTDI232.
To upload, you need to hold switch S2, press and release switch S1 and then release S2, then tell the IDE to upload.
Someone just suggested this circuit to me: https://github.com/makerbase-mks/MKS-WIFI/blob/master/hardware/MKS%20TFT%20WIFI%20V1.0_002/MKS%20TFT%20WIFI%20V1.0_002 % 20SCH.pdf
I used the 3V3 power supply of the FTDI as a precautionary measure, and I measured ~ 2V on the power pin of the microcontroller. Then I told myself to check the pins of this module and I found out that the pins Rx and Tx are reversed, or at least the marking on the board is reversed.
I uploaded a Blink sketch and it works fine. This board does not give me access to all the GPIO pins of the microcontroller, so I will look for how to use it with an Arduino.
