MK-LM-01H LoRaWAN Module Zvikuru

Tsananguro pfupi:

Module yeMK-LM-01H imodule yeLoRa yakagadzirwa naSuzhou MoreLink yakavakirwa pa STM32WLE5CCU6 chip yeSTMicroelectronics. Inotsigira LoRaWAN 1.0.4 standard yeEU868/US915/AU915/AS923/IN865/KR920/RU864 frequency bands, pamwe neCLASS-A/CLASS-C node types uye ABP/OTAA network access methods. Pamusoro pezvo, module iyi ine mamodheru akawanda ane simba shoma uye inoshandisa UART yakajairwa ye external communication interfaces. Vashandisi vanogona kuigadzirisa zviri nyore kuburikidza neAT commands kuti vawane ma network eLoRaWAN akajairwa, zvichiita kuti ive sarudzo yakanaka kune ma IoT applications aripo iye zvino.

一. Pfupiso

1.1 Mbiri

1.2Zvinhu

1.Maxima inotumira simba kusvika ku20.8dBm, ichitsigira kugadzirisa software uye kugadzirisa ADR.
2. Dhizaini yegomba rezvidhindo kuti zvive nyore kusungirira.
3. Mapini ese echip anoburitswa ne led, zvichiita kuti zvive nyore kugadzira chimwe chinhu.
4. Hukuru hwemagetsi hwakafara, hunotsigira simba remagetsi re1.8V kusvika 3.6V.
