1. Overview MMJ05-1B-015 module is a "pole" series LoRa RF terminal module developed by Star. This module integrates LoRa's core radio frequency chip LLCC68 and its peripheral circuit, adopts serial interface to interact with user equipment for data and instruction, and can conveniently provide users with fast LoRa wireless terminal communication and other services. MMJ05-1B-015 module size is 20mm*8.9mm*2.

platform to the module. 2.2.4 Module status indicator Module status indicator pin is the 13 busy pin. If the user sends serial port data to the module, check the level status of the BUSY pin. The user can send serial port data to the module only when the BUSY pin is high level (idle state). After the module receives user data, BUSY pins will be lower, indicating that the module will carry out data communication.
The typical definition of antenna bandwidth is the frequency range where the reflected wave attenuation is less than -10dB or VSWR is less than 2, that is, the frequency range where the reflected power of the antenna is less than 10%. 4. Product material object Module size: 20mm*8.9mm*2.
FCC Caution. §15.19 Label requirements. This device complies with part 15 of the FCC Rules. Operation is subject to the following two conditions: (1) This device may not cause harmful interference, and (2) this device must accept any interference received, including interference that may cause undesired operation. §15.21 Information to user. Any Changes or modifications not expressly approved by the party responsible for compliance could void the user's authority to operate the equipment. §15.
KDB996369 D03 Requirements 2.2 List of applicable FCC rules List the FCC rules that are applicable to the modular transmitter. These are the rules that specifically establish the bands of operation, the power, spurious emissions, and operating fundamental frequencies. DO NOT list compliance to unintentional-radiator rules (Part 15 Subpart B) since that is not a condition of a module grant that is extended to a host manufacturer. See also Section 2.
as a specific host also approved with the module. Explanation: this module is a Single approval module 2.5 Trace antenna designs For a modular transmitter with trace antenna designs, see the guidance in Question 11 of KDB Publication 996369 D02 FAQ – Modules for Micro-Strip Antennas and traces. The integration information shall include for the TCB review the integration instructions for the following aspects: layout of trace design, parts list (BOM), antenna, connectors, and isolation requirements.
2.7 Antennas A list of antennas included in the application for certification must be provided in the instructions. For modular transmitters approved as limited modules, all applicable professional installer instructions must be included as part of the information to the host product manufacturer. The antenna list shall also identify the antenna types (monopole, PIFA, dipole, etc. (note that for example an ―omnidirectional antenna‖ is not considered to be a specific ―antenna type‖)).
2.10 Additional testing, Part 15 Subpart B disclaimer The grantee should include a statement that the modular transmitter is only FCC authorized for the specific rule parts (i.e., FCC transmitter rules) listed on the grant, and that the host product manufacturer is responsible for compliance to any other FCC rules that apply to the host not covered by the modular transmitter grant of certification.
