MK-LM-01H LoRaWAN Module Specifikationer

Kufotokozera Kwachidule:

Module ya MK-LM-01H ndi module ya LoRa yopangidwa ndi Suzhou MoreLink kutengera chip ya STM32WLE5CCU6 ya STMicroelectronics. Imathandizira muyezo wa LoRaWAN 1.0.4 wa ma frequency band a EU868/US915/AU915/AS923/IN865/KR920/RU864, komanso mitundu ya ma node a CLASS-A/CLASS-C ndi njira zopezera ma netiweki a ABP/OTAA. Kuphatikiza apo, moduleyi ili ndi mitundu ingapo yamagetsi otsika ndipo imagwiritsa ntchito UART yokhazikika yolumikizirana yakunja. Ogwiritsa ntchito amatha kuyisintha mosavuta kudzera mu malamulo a AT kuti apeze ma netiweki a LoRaWAN okhazikika, zomwe zimapangitsa kuti ikhale chisankho chabwino kwambiri pakugwiritsa ntchito ma IoT omwe alipo pano.

1.1 Mbiri

1.2 Zinthu Zofunika

1.Maxima imatumiza mphamvu mpaka 20.8dBm, kuthandizira kusintha kwa mapulogalamu ndi kusintha kwa ADR.
2. Kapangidwe ka dzenje la sitampu kuti likhale losavuta kusungunula.
3. Ma chip pini onse amatulutsidwa, zomwe zimathandiza kuti chitukuko chachiwiri chikhale chosavuta.
4. Mphamvu yopezera magetsi ambiri, yothandizira mphamvu ya magetsi ya 1.8V mpaka 3.6V.

Zindikirani

Miyeso yomwe ili pamwambapa ndi miyeso ya zikalata za kapangidwe kake. Kuti mulole zolakwika za PCB, miyeso yodziwika bwino ya kutalika ndi m'lifupi ndi 14 * 20mm. Chonde siyani malo okwanira pa PCB. Njira yotetezera chivundikirocho ndi yopangidwa mwachindunji ndi SMT (Surface Mount Technology). Pokhudzidwa ndi kutalika kwa solder, makulidwe ake enieni ndi kuyambira 2.7mm mpaka 2.8mm.
