I would probably immediately buy, extra battery TOH, slide-out-keyboard TOH and wireless charger TOH at least

Going by Jollaās original poll for TOH, I suspect that a Keyboard TOH was what people were most interested in. (But itās so difficult to get right, I donāt think Jolla have any interest in trying to do one again.)

wireless charging would be nice, USB-C ports are sometimes not so durable.
An e-ink screen to read ebooks would also interests me.
Iād put good money on a slide-out keyboard, but unfortunately:
16:29:17 <rainemak> #info <Jolla> Currently, our plans do not include keyboards #sailfishos-meeting log (July 2, 2026)
Iād be happy with a multifunctional one that could feature programmable physical keys, notifier LEDs, jack 3.5mm, charger port, SD card (that I can use and remove without removing the SIM).
I would use the charging port of TOH so I can easily buy another TOH easily replace it the USB gets broken, without sending my phone anywhere.

I would LOVE a good DAC TOH with an 3.5mm audio jack. I just miss my aufio jack so much

Ooooh thats a great idea! It would have to go somewhere tho. Would you mind a bump? Where would you want that bump - centered, on a side, bottom, top?
I guess it should interfere as little as possible with holding the phone so its gonna be some work to choose a spot.

What about on the side opposite the camera bump? Then the phone will be laying more flat on the table.

If you buy a magnet-Adapter for your USB-C you have no Problem either.
My main fear is damage due to repeatedly plugging/unplugging the charger, also damage while a USB-C adapter is plugged (e.g. USB-C/jack adapter, while I hold the phone). This isnāt solved by the magnetic cover. Still a good idea, I might buy one.

Donāt go for a no-name brand ā go for this one.
Donāt use the swivelling one; it has a round mounting plate ā this will interfere with the case bumper (if fitted)
Iāve got it on my JP2 too ā it works a treat.
Iāve had it installed on my XA2+ for ages as well.
Alright I had not understood the concept. I see now it solves the issue with daily charging. However, it prevents me from using a DAC/3.5mm adapter.
Yes, unfortunately thatās true. Iāve also got a working DAC/3.5 mm adapter (for the JP2) lying around here.
I havenāt managed to sort out that problem yet either. If the magnetic adapter were fully wired, youād still need a DAC with exactly that same connector ā but unfortunately thatās just wishful thinking.
The magnetic adapter company could provide a female adapter for the DAC.

a big problem is that the I2C doesnt provide the bandwidth you need for proper audio. Idk if I3C is supported yet but that would make it at least doable, but thats kernel work.
if there is no I3C it is simply impossible i think to add an audio jack right now so sadly I am blocked. But I will add it to the list of things that are targeted for development with the TOH DevKit over at TOH DevKit: getting started with The Other Half development, a DIY breadboard dev cover . This way if I canāt make it someone else probably can 
What I could do is make a TOH with which you connect via bluetooth for data but that seems - suboptimalā¦

Without I3C, it still can be done by a TOH with a low-profile USB plug that permanently stays into the main USB-C socket. Then the TOH subdivides the USB-C into different functions, like a docking station.
true and absolutely plausible. But thats not exactly a TOH as I understand it cause in some way uses / occupies the port. It would be way more optimal if it could just use the interfacing pins intended for exactly such TOHs imo.
But as I said - youāre not wrong. That will work just as well as if you went Phone > Bluetooth in Cover > Jack in Cover. This would then leave the usb free but introduce the bluetooth finagling.
So either way suboptimal unless we have I3C but I would love to see someone build what you are describing. There are way to little TOHs out there imo

I think the amount of I2C phones is going down though. I already got my dust-selfi-camera-replaced phone and I think they might have also switched that subboard to I3C. Id try if i know how 
Else you can always contact jolla to get one though if i recall correctly.
Id love a headphone jack. And placement i wouldnt care. As long as the phone lies flat it can also take up the whole back (and not cover the back camera to make the wobble go). That bothers me the most. Location is not important to me as long as it works and the audio is good.

I was wondering about this a while ago. If we did have an interrupt pin, we could do I2S using SDA/SCL + the int pin for interleaved data ā¦ audio over I2C wonāt work as you suggest.

My dust replacement is about to arrive next week. In the mail they announced that the unit will have the I3C board, my impression was that all new shipments will have the I3Cā¦
This Ć®, I would love it!
