MK-LM-01H LoRaWAN Module Specificaton
Short Description:
The MK-LM-01H module is a LoRa module designed by Suzhou MoreLink based on STMicroelectronics’ STM32WLE5CCU6 chip. It supports the LoRaWAN 1.0.4 standard for EU868/US915/AU915/AS923/IN865/KR920/RU864 frequency bands, as well as CLASS-A/CLASS-C node types and ABP/OTAA network access methods. In addition, the module features multiple low-power modes and adopts a standard UART for external communication interfaces. Users can easily configure it via AT commands to access standard LoRaWAN networks, making it an excellent choice for current IoT applications.

三. Mechanical Dimensions and Pin Definitions
3.1Outline Dimension Drawing
Note
The above dimensions are the document dimensions for structural design. To allow for PCB cutting edge errors, the marked length and width dimensions are 14*20mm. Please leave sufficient space on the PCB. The shielding cover process is direct SMT (Surface Mount Technology) integrated molding. Affected by the solder height, its actual thickness ranges from 2.7mm to 2.8mm.

| Note 1: Pins PA6 and PA7 are used as module internal control RF switches, where PA6 = RF_TXEN and PA7 = RF_RXEN. When RF_TXEN=1 and RF_RXEN=0, it is the transmit channel; when RF_TXEN=0 and RF_RXEN=1, it is the receive channel.
Note 2: Pins PC14-OSC32_IN and PC15-OSC32_OUT have a 32.768KHz crystal oscillator connected internally in the module, which can be selected for use by users during secondary development. Note 3: Pins OSC_IN and OSC_OUT have a 32MHz crystal oscillator connected internally in the module, which can be selected for use by users during secondary development. |
