I. Lero tiend "Shelf mar buge mag elektronik"
"Shelf mar buge mag elektronik" ok en gino ma iketoe gik moko to en gino maduong' ma somo kata gino ma nigi rieko mar somo. Gima duong’ ma ochung’ne en loso kaka itiyo gi buge kod somo ma ne itiyogo e ute somo kata shelf mag buge machon e yor dijital.
II. Gik madongo kod tije mag shelf mag buge mag elektronik
1. Gigo ma itiyogo kod tijegi
E Ink Maduong’: Ochakore gi inch 7.8 nyaka inch 13.3 kata madongo moloyo (madongo ahinya moloyo gik ma ng’ato nyalo somo ma nigi inch 6–7), omiyo ng’ato bedo gi thuolo mar somo ma chal gi buge kata gaset ma nenore. Thothgi tiyo kod teknoloji mar E Ink mondo giyud mor e wang’gi kendo gitiyo gi teko maber.
Prosesa maduong’: Otiyo gi ARM Cortex A kata Cortex M (AP) kata MCU, ochung’ ne tije mag sistem, loso gik moko, rito fainde, kod tudruok e mbui.
Paro: Oting’o RAM (mar tije mag seche adier) kod Flash/ROM (mar kano mwandu).
Tudruok maonge waya: Wi-Fi en gima owinjore; model ma malo nyalo medo 4G/5G kata bulututh.
Betri: Nitie nyalo maduong’- mar konyo seche mag somo mabor.
Yore mag Keto: Siko mar skrin ma mulo, ka moko nigi baton mag loko pej -.
Gik ma itiyogo: USB{0}}C (mar chajo kod oro weche), kendo nyalo bedo ni nitie kar keto kad mar MicroSD.
Gik ma itiyogo e winjo: Spika kod maikrofon (e model moko moyier) ma itiyogo mar winjo buge mag winjo kata keto dwol.
2. Program mag kompiuta kod Tije Madongo
E-Somo Bug: Ochung' ne fomat madongo (EPUB, PDF, MOBI, TXT, kod mamoko) ma nigi chenro ma inyalo loso kaka idwaro (font, chenro, ondike, loko).
Tiyo gi Laibri: Oloso gik madongo kaka laibri ma nenore, ma miyo inyalo ketogi e kidienje mopogore opogore, manyo, ipogo, kendo keto ranyisi mag buge.
Kaka Inyalo Yudo Gik Moting’o: Otudore kokalo kuom Wi Fi gi duka mag buge ma ni e mbui (ma oger kata ma nigi ng’at machielo, kaka JD Somo, WeChat Somo, Kindle) mondo iyud gik moko kendo iyud kaka somo dhi nyime.
Oboke kod Oboke: Oyiene kawo oboke-, keto ler, kod oboke kokalo kuom stylas kata kibod.
Tiyo gi Oboke: Oketo pach kuom somo PDF, ndiko weche, kod loso kendo; moko konyo neno barupe mag Ofis (maber ne tich/somo).
Gik ma Omedore mag Program: Sistem ma oyawore (kaka Android) miyo jogo ma tiyo gi programno keto program mag somo kata ma konyo.
