Hi all,
i’m about to try a RAK-14000 e-ink, https://aliexpress.com/item/1005003431595237.html
Just to be sure, does that work together with RAK4631 on RAK19007?
Is it the best choice or are there larger and/or cheaper modules available?
And how is that connected to the RAK19007? Is there a cable included? I see no one from the description…
It is the only supported eink model, it does not work with a GPS and has small ribbon cables to connect the display and three button pad to the 40 pin module. There is not really any cases available.
Currently the 1.3" oled is the most popular screen.
Anyone of the other added e-Ink displays can be selected when building from source, simple just change the e-ink display by uncommenting select e -ink display model in the code, refer to screenshot
Connect up using a RAK13002 IO board , RAK1400 board, DESPI-C02 or Waveshare e -ink Hat or to the e-Ink itself if it has its own driver board
Refer this PR for links to.purchase the other e-Ink displays
I have justed tested 2 new diplays also
2.9 and 5.83 inch

Excellent, just excellent! That’s what i wanted to try in the end, a real display of a decent size.
So it just needs a I2C link.
Maybe you can show us some links where to order the displays you took? Just for some orientation…
From the video i also got my question answered how the separate e-ink board is connected to the RAK19007.
These e-Ink displays use SPI and needs 5/6 gpio pins in total and 3.3/5v and GND
That why i was able to use a Ethernet connection
The purchase links are included in the pull request i posted above
Good display supplies Waveshare and other companies with displays
The others i used are from MHET-Live and WeActStudio
The 2.9 is quite a nice size in my opinion

I do now own a RAK14000. It is connected to the RAK19007 now. Cables should be connected correctly, just like shown at https://aliexpress.com/item/1005003431595237.html
The display does not show anything. Do i need to change some parameters? I already played around a bit, but…
Your advice could be helpful.
Uuuh, what a shame. I should have run the _eink firmware. Problem solved. Works nicely…
Can you advise on the fw version you used to get RAk1400 working please.
I have tried latest stable -einkfw uf2 file and RAK runs fine but if I plug in screen will not boot
I am having the same issue as @h0gboy. Running 2.2.22 on RAK19007 with RAK4631 and e-ink RAK14000.
Can Have module for e-ink and buttons plugged in. But as soon as I plug in the screen, it fails to boot / can’t see COM.
@mark.birss thank you for sharing this!
You wouldn’t happen to have another RAK14000 board that has the additional screen-print near “ID1” (bottom right corner) like in this image:
I’m also on the forum for RAK trying to figure this out. And that is the only physical difference I can see. And there are others on both forums claiming the same issue.
No, i only got the one long ago, as i have been using the RAK13002 io board with DESPI-C02 or other e-ink driver boards with few other e-ink displays 1.02-5.65 inch
Sorry, if my question doesn’t fit this thread, but I also want to connect the RAK14000 to my RAK19007 with RAK4631 (for the Meshenger project from tropho23/QuantumShadow3D/TonyG), but how can I connect the RAK14000, if I need the I/O slot for the I/O board (buzzer, vibramotor, LED)? There doesn’t seem to be a possibility to connect the RAK14000 through SDA/SCL/GND/VCC, or am I mistaken? Or does a “loop through” cable exist (kinda like SCSI, yes, I’m old ;-), which I can fit in between the WisBlock and I/O board? My son, with whom I’m building this project, told me, that he had read about someone, who had fit the RAK14000 in the Meshenger, but can’t find the link anymore…
