Hkrang ni: USB-C (charge galaw na matu hte data htawt sit na matu), MicroSD card bang na shara mung mai byin ai.

Nsen hte seng ai lam ni: Nsen laika buk hpe madat na matu (sh) nsen bang na matu, speaker hte microphone (lata da ai model ni hta).

2. Software & Madung Magam Bungli ni

E-Laika Buk Hti Ai Lam: Laika buk hti ai lam (EPUB, PDF, MOBI, TXT, etc.) hpe madi shadaw ya nna, laksan masat da ai lam ni (font, layout, notes, ga gale ai lam) hpe madi shadaw ya ai.

Laika Dum Hkringmang Dap: Hkum hkrang laika dum zawn, mahkawng da ai laika buk kaba ni hpe hpawng de ya nna, garan ginhka ai, tam ai, garan ginhka ai, bookmark galaw ai lam ni hpe galaw ya lu ai.

Content Access: Wi-Fi hku nna online laika buk dut ai shara ni (JD Read, WeChat Read, Kindle zawn re ai ni hpe gawgap da ai) de matut mahkai nna, laika hti ai lam hpe download galaw na matu hte sync galaw na matu galaw ai.

Notes & Annotations: Stylus (sh) keyboard hku nna note- hpe la na, n-gun jaw na, hte laika man ni hpe ka na matu ahkang jaw ai.

Document hpe hparan ai lam: PDF hpe hti ai, laika ka ai, reflow galaw ai lam ni hpe madung tawn ai; nkau mi gaw Office document ni hpe yu na matu madi shadaw ya ai (bungli/hkaja na matu kaja dik ai).

App Extension ni: Hpaw da ai system ni (ga shadawn, Android) hta lang ai ni hpe masum ngu na -hti hti ai (sh) akyu rawng ai app ni hpe install galaw shangun ai.

III. Electronic laika buk shingdu hta nga ai Crystal Oscillator ni: Htingnu ni, Hkrang ni, hte Laksan Lam ni

Electronic laika buk tawn da ai shara ni gaw, grai sawng ai n-gun rawng ai ladat ni hku nna, module amyu myu a matu laklai ai aten ladaw npawt nhpang ni ra nga ai. Lahta e, shingra tara hku nna crystal oscillator a hkrang masa ni hpe garan kachyan da ai:

IV. Ndai Crystal Oscillator ni hpa majaw ra kadawn ai kun?

Tengman ai aten jaw ai "Myit masin n-gun"
Processor, matut mahkai module, interface zawn re ai digital arung arai ni gaw bungli galaw ai lam ni hpe hkan sa na matu ngang grin ai ahkying masat kumla ni hpe kam hpa nga ai. Shanhte n nga yang, system ni gaw n kaja ai (sh) n tara ai hku bungli galaw na re.

Zuphpawng Module-Laksan ra kadawn ai lam ni

Processor a bungli galaw ai lam: -frequency tsaw ai, ngang grin ai main clock (PLL law htam ai hku nna) gaw CPU hpe hkrak hkra galaw ya lu ai.

Wireless Quality: Wi-htuk manu ai lam, nsen n law ai (ga shadawn, 26/40MHz) ni gaw Wi-Fi/BT transceiver ni a matu ahkyak ai rai nna, matut mahkai lam a ngang grin ai lam, data rate, signal quality ni hpe hkrak hkra hkra machyi shangun ai.

Aten hpe hkan sa ai: 32.768kHz RTC crystal gaw yup ai aten hta pyi, ultra-n-gun n law ai aten hpe hkrak hkra hkan sa ai.

Magam Bungli Hkringmang Dap: Touch sampling, display hpe bai gram lajang ai, nsen hpe bai madat ai shaloi, bungli ni hpe hkrak hkra galaw na matu, ap nawng da ai ahkying aten ni ra ai.

Kaji kajaw galaw ai hpe madi shadaw ai
Ntsa kaw tawn da ai (SMD) nlung ni (3225, 2520, 2016, 1612) gaw, n-gun n law ai PCB ni hte hkrak nna, dai ni na aten na electronics ni a shara n law ai hpe hkap la lu ai.

N-gun rawng ai hte kam hpa mai ai lam hpe hkam la ai
Crystals ni gaw nbung laru galai shai ai lam hte n-gun rawng ai lam ni hpe hkam sharang ra ai, n-gun ja ai frequency-n-gun rawng ai lam hte aten galu-hkam sharang lu ra ai.

Power lang ai hpe hkang ai
Low-power RTC crystals ni gaw standby aten hpe galu shangun ai, kaga crystals ni a matu power hpe atsawm sha hkang lu ai gaw n-gun yawng lang ai hpe shayawm ya ai.

Manu jahpu hte bungli galaw ai lam hpe rap ra hkra galaw ai
Hpaga galaw ai ni gaw, package size, accuracy, brand ni hta shai hkat ai lam ni hpe myit yu nna, manu kaja dik ai hpaji masa ni hpe hkan sa ai crystal ni hpe lata ma ai.

V. Ngut nna tsun ai

Electronic laika buk tawn da ai shara ni hta amyu myu, -hpaji rawng ai kristal oscillator ni ra nga ai. Shanhte a system design hte module langai hte langai a laksan ra kadawn ai lam ni hpe chye na na matu (package, frequency, load capacitance, bungli galaw ai lam hpe masat masa galaw ai lam) gaw ahkyak dik rai nga ai. Processor kaw nna wireless module hte RTC ni du hkra, ndai aten masat masa galaw ai arung arai ni gaw, jak a bungli galaw ai lam, ngang grin ai lam, lang ai ni a mahkrum madup ni hpe hkrak sha shadut ya ai majaw, electronic laika buk shingdu shingra tara hta n mai garan kachyan ai lam ni byin wa ai.
