MK-LM-01H LoRaWAN Module Ibisobanuro birambuye

Ibisobanuro bigufi:

Moduli ya MK-LM-01H ni module ya LoRa yakozwe na Suzhou MoreLink ishingiye kuri chip ya STM32WLE5CCU6 ya STMicroelectronics. Ishyigikira LoRaWAN 1.0.4 isanzwe kuri EU868/US915/AU915/AS923/IN865/KR920/RU864 frequency bands, hamwe n'ubwoko bwa node za CLASS-A/CLASS-C hamwe n'uburyo bwo kugera kuri network ya ABP/OTAA. Byongeye kandi, module ifite uburyo bwinshi bwo gukoresha ingufu nke kandi ikoresha UART isanzwe ku miyoboro y'itumanaho ryo hanze. Abakoresha bashobora kuyishyiraho byoroshye binyuze mu mabwiriza ya AT kugira ngo bagere kuri network zisanzwe za LoRaWAN, bigatuma iba amahitamo meza kuri porogaramu za IoT zigezweho.

一. Incamake

1.1 Umwirondoro

1.2 Ibiranga

1.Maxima yohereza ingufu kugeza kuri 20.8dBm, ishyigikira ivugurura rya porogaramu na ivugurura rya ADR.
2. Igishushanyo mbonera cy'umwobo wo gupfunyika kugira ngo byoroshye gupfunyika.
3. Udupira twose tw’icyuma dushyirwa hanze, byoroshya iterambere rya kabiri.

三. Ibipimo bya Mekanike n'Ibisobanuro bya Pin

3.1 Igishushanyo cy'ingano y'umurongo

Icyitonderwa

Ibipimo byavuzwe haruguru ni ibipimo by'inyandiko ku gishushanyo mbonera cy'inyubako. Kugira ngo habeho amakosa yo gucana PCB, uburebure n'ubugari byagaragajwe ni mm 14 * 20. Siga umwanya uhagije kuri PCB. Uburyo bwo gukingira ni ubucucike bwa SMT (Surface Mount Technology) buhujwe. Bitewe n'uburebure bwa solder, ubunini bwayo nyabwo buri hagati ya mm 2.7 na mm 2.8.
