Plug and Play LoRa USB Kit for Evaluation
Description MEK-D8945AL is a LoRaWANTM evaluation kit based on Maxiit’s LoRa module DL7812/DL7612 and FT232 chipset. It integrated with the newest version LoRa protocol LoRaWAN 1.1 and LoRaWAN 1.0.2, support AT command control and secondary development on MCU. Support USB to Serial port, drive-free, adds LoRa connectivity to any windows, Linux or IOS operating systems. It lets IoT (Internet of Things) integrators, network testers, and hobbyists get connected to LoRa® networks faster, diagnose network issues more easily, and build new and exciting connected devices. Features USB – USB 2.0 port, Plug and Play Compliance to LoRaWAN™, Support lorawan1.0.2, 1.0.3 or 1.1 protocol, Class A/B/C Support AT command control and secondary development on MCU Use more stable SWD debug interface, SPI, GPIO interface reserved LoRa ConnectivityMaxiiot DL7612 – Support EU868MHz/US915MHz/AS923MHzMaxiiot DL7812 – Support EU433MHz/CN470MHzReceiver Sensitivity – down to -139 dBmTX Power-adjustable up to +18.6 dBmRange – Effective communication range 3~5 km 3x user LEDs（ Tx LED, Rx LED, Power LED） Dimensions – 64mm*23mm*12mm(with Pin Header) Support Windows, Linux, and IOS operating systems Interface Downloads MEK-D8945AL LoRa EVK User Manual LoRaWAN1.0.2 MAXIIOT DL7X1X-AT-CMD-LRWAN1.0.2-V1.7 LoRaWAN1.1 MAXIIOT DL7X1X-AT-CMD-LRWAN1.1-V2.0 Operation guide 1.
