Questions about the hardware #2

Open ahmedshah1494 opened 3 years ago

ahmedshah1494 commented 3 years ago

I have a couple of questions about the setup.

1-The usb jack attached to the pogo pins is a micro-usb jack, right?

2-Is the jack on the usb-C breakout a female? Do you then use a usb-C to usb-C to connect the breakout board to the usb-C port on the remarkable?

Thanks

ddvk commented 3 years ago
  1. yes, usb micro
  2. i use male, but there are people that have used a female one with a cable (i didnt have a usb 3.1 cabel) as long as the all the pins are connected

Thanks a lot for responding. Just to make sure I got this right, I need to get a male usb-C breakout with a B8 pin, plug it into the powered off device, and attach a 10K resistor between GND and B8, right?

ddvk commented 3 years ago

yes, then power up

there are links in the readme to aliexpress

Hi! I'm buying also the components to have access to recovery, OTG, etc (https://github.com/dps/remarkable-keywriter/issues/14). Just found these kind of pogo connectors with magnets: https://es.aliexpress.com/item/1005001587511989.html. For anyone interested.

In case this helps anyone that is impatient and doesn't want to wait for their AliExpress order to come in and you own or have access to a 3D printer. :smile:

Here is a support bracket to use breadboard patch cables as "pogo" workarounds. It's a bit touchy, but it will work in a pinch.

Hey, for anyone interested, as it has been discussed in https://github.com/dps/remarkable-keywriter/issues/14, pogo pins with magnets do not work directly on the remarkable 2, because magnets are not aligned. However, you can use a female connector for the magnets and the male connector for the actual connection. And with some soldering do the trick. Pics:

That's great! How reliable/easy to re-connect is it?

isman7 commented 3 years ago

The idea is to use the magnets, so it's magnetic, the problem is that we have only magnets in one side of the connector, so the Pogo pins have one degree of liberty that we don't want. But, connecting it in plain surface i.e. the folio, suffices to have a good connection.

What I'm thinking is to explore an integration with the USB-C connector all in one board or something, this would fix the free liberty degree.

I've made this gif to clarify the re-connection:

Hope it resolves some doubts!

That is awesome! So that is just two male pogo adapters?

ddvk commented 3 years ago

i made a holder in freecad, but havent ironed its kinks yet, i ll push the file

isman7 commented 3 years ago

Thanks! Well, as they are sailed in pairs, I've used the male adapter as the actual connector and the female adapter for the magnets. Possible improvements are:

I really didn't found any docs about the magnets so, some days ago I played with magnets they are composite magnets with reversed polarity +-+-, I did some review on Twitter (It's in Catalan, so you can google translate or enjoy the pictures!): https://twitter.com/ismansiete/status/1352681340777463810

there are links in the readme to aliexpress …

Hi, this link is probably bad. https://www.aliexpress.com/i/4000026719770.html Can I use this? Or another? https://www.aliexpress.com/item/4000221550930.html

this one is female, you'll need a cable that has a b8 connection
