Support for reMarkable 2

[briankaemingk]

Any idea what it would take to support rm2? I have one, and I'd be happy to help with the development and testing, but I might need some tips to get started. Thanks!

Update: it looks like one can use an external keyboard by hooking up to the pogo pin connectors, thanks to user ddvk I'll try to get the right connector, give this a try, and report back.

Just checking in to see if you tried it. I followed the link to the Reddit thread which had some information, but not a link to the actual pogo accessory they used. (I'm not very familiar with pogo connectors, there seem to be multiple types and if you happen to have a link to an online store where I can buy one and try it myself that would be great). Thanks!

[briankaemingk]

Sure, happy to help. I haven't tried it, but so far, I bought the following:

• Micro USB breakout
• Here's what I bought for Pogo pins
• another version also available here with longer shipping to the US

In the next couple of days, once I get everything ready, I'll try it and report back...

Thanks for the prompt response! This seems like hardware work is involved here, i.e., you get the Micro USB breakout, and the Pogo pins, connect them somehow and then attach the assembly to the rM2 somehow. I could be wrong, never tried anything like this before. I was thinking there would be some kind of existing hardware dongle that would go from the USB to Pogo (although that still leaves the issue of how to attach that securely to the device).

[briankaemingk]

Yeah, I'm new to all this stuff too. It looks like I can attach these parts together without soldering. I don't have my hands on them yet, but I tried to buy parts where the pins from the pogo adapter slide into the micro usb breakout. Then you can attach it all to a Micro USB OTG adapter like this one and hook it all up to a regular old USB keyboard.

I'm just trying to recreate the setup using the pics from the comments in this reddit post provided by this fine github user.

If you find an easier alternative, please let me know. Otherwise, I'll report back as well. Thanks!

[rjainms]

OK, makes sense, looking forward to what you find!

[briankaemingk]

Alright, so I got the parts, and they seem to fit fine, but I can't keep the connection with my hands, so I guess I'll have to solder the micro usb breakout to the pogo pin adapter. Never done that before, but I can pick up an iron for pretty cheap, so I'll give it a try and report back...

[rjainms]

Cool, thanks! And have you thought about how the assembly will stick to the device? Are the pins magnetized?

No they aren't magnetized.. Not sure, maybe some clips or rubber bands...

After years of looking on I just joined this game. Are y'all working with the pogo pins because you've found the usb-c port can't connect to a keyboard, or because you have other intentions?

[briankaemingk]

Correct. No source I've found has figured out how to get usb OTG connections work through the USB C port. More details here: https://remarkablewiki.com/tech/rm2_otg_pogo.

Brian, for attaching the assembly to the device: it seems the edge near the pogo dots on the device is magnetized. On Sat, Dec 26, 2020 at 12:51 PM briankaemingk <notifications@github.com> wrote:

Hi!

I'm also interested in hack this a little bit. As an electronic engineer I strongly recommend to solder everything, I've seen students spending hours debugging I2C communications because they only put through-hole connects attached and not soldered.

I've been looking for assembled versions of a pogo-to-usb adapter and neither found one. I'm now researching a for keyboards that had similar connectors. These seem pretty much the same kind of connector: https://www.google.com/search?q=chuwi+ubook+keyboard+pogo&tbm=isch&ved=2ahUKEwj87Nrj8YXuAhUFNxoKHePNCGgQ2-cCegQIABAA&oq=chuwi+ubook+keyboard+pogo&gs_lcp=CgNpbWcQA1DoJ1iCKmDGK2gAcAB4AIABUIgBlgGSAQEymAEAoAEBqgELZ3dzLXdpei1pbWfAAQE&sclient=img&ei=hO70X_yaBIXuaOObo8AG&bih=512&biw=1366&safe=active

I will be posting also updates if I can purchase some material.

[briankaemingk]

Sounds good! Please keep us updated. I'll post pictures as well when I get my materials and try it.

@isman7 do you happen to know which end the VBUS connection is on that keyboard? For the rM2, the VBUS connection is closest to the USB-C port. Would be somewhat unfortunate if one could connect the tablet, but it faced the wrong direction.
