K3 or Kindle Keyboard 167 dpi (third generation) Oldest to later get azw3 support. Wifi or Wifi + 3G
DXG or B009 (a DX with better contrast, Mobi & PDF, abysmal, 150 dpi also 2nd gen too, thoough after K3) 3G only, no WiFi.
These early ones have 3.5mm jack, at least some have speakers, rudimentary MP3 and text to voice.


Various versions Gen 4 without keyboards. 1: K4 aka K4NT (no touch and 8 physical buttons and a 4-way button with another button in the middle. 2: Kindle Touch

A Gen 5 (with or without touch?). Similar to Gen 4 but faster

Basic all 167 dpi till 2022 when it got 300 dpi.
A Gen 6 Touch, 2012 now called Kindle Basic.
Gen 7 Basic. Full touch but no frontlight. First model called a Basic.
Gen 8: Basic. Still 167 dpi but Bluetooth for sight impaired (Voice view). 2016. also called KT3 or Basic 2
Gen 10 Basic: 167 dpi, First front light on Basic. 2019
Gen 11 Basic: First 300 dpi on Basic, front light, 2022. Similar to a 2015 PW3, but USB-C and better 16G storage.

Paperwhite adds a front light and all are touch.
Gen 5: 212 dpi. 2012 PW 1
Gen 6: 212 dpi. 2013 PW 2
Gen 7: 300 dpi. 2015 PW 3 (first decent Kindle & does KFX). Later PW3 for some countries had extra storage, e.g. Manga edition. Audio via USB adapter, no MP3, but Voice view via download.
Gen 10: PW4. Options for 32 GB Wi-Fi and 4G LTE. Flush screen less clear than PW3! Bluetooth for Voiceview. 2018.
Gen 11: PW5. 2021. USB-C

Voyage
Gen 7: Basically an expensive PW 3, said to have best screen. 2014, one month after PW3.

Oasis page buttons, front light, 7″ screen, 300 dpi
Gen 8: Oasis 1, (poor battery life without cover) 300 dpi. 2016

Gen 10: Oasis 3, 2019

Scribe 10.3″ approx, 300dpi, Wacom EMR digitiser and stylus, but annotation seems to need documents via Amazon, not sideloaded. No on-device conversion to text or direct drawing on sideloaded PDF?

Unlike Kobo, you can never down grade without a jailbreak.

Kindle naming is confusing with many nicknames. The Fire LCD tablet based on Android was confusingly a Kindle Fire from 2010 to 2014.

I may have made mistakes.
See https://wiki.mobileread.com/wiki/Kindle
and https://en.wikipedia.org/wiki/Amazon_Kindle
And https://www.androidauthority.com/whi...-have-1073996/

The definitive thing is usually the first four digits of the serial number (sometimes 1st six) (on the device settings and any matched Amazon account).

I don't know what a KT3 is?
There are many nicknames and Amazon has sometimes later changed what they called an earlier ereader!
Is a KT3 the 3rd model with touch?


mobi = old mobi /azw / kf7. No embedded fonts. Only HTML3, no CSS files.

There are multiple fixed layout formats and interactive.

azw3/kf8. Much of HTML 5, CSS, embedded fonts and similar to epub2. Supported if the Kindle has a "Publisher" Mode/Theme.

Dual Mobi is azw3 & mobi in the same file. DXG only sees the Mobi. K3 sees either (publisher mode) and later kindles might only see the azw3.

KFX. Incremental download, always encrypted. Different layout rules (Amazon calls it enhanced). Needed for Sticky Notes. At least PW3 and later support it.


Edit
The Android Authority link writes
Kindle Basic 2 (2016) = 8th gen = KT3
i.e. Third Touch model by their site.
