LNQNSM01 Lynq Module User Manual, revision 6 Updated 6/26/2020
1. Features The LNQNSM01 LoRa module provides a turnkey solution for leveraging the Lynq Network Stack. It allows for the commissioning of networks using a simplified serial peripheral command interface. The FCC/IC certified design allows for rapid product development and fast time to market. The front-end design of this module allows for operation at the limits of transmit power, providing longer range communication than competitive LoRa modules.

7.2. LNQNSM01 Pin Diagram 8. Typical Connection 8.1. Serial Connection to Host Processor The LNQNSM01 has a UART serial peripheral interface dedicated to communication with the module via a host controller or processor. Default UART specifications are provided in the table below and complete command interface documentation can be found in the “LNQNSM01 Module Command Interface Reference Manual” (DOCUMENT NUMBER HERE).
8.1.1. Default UART Interface Settings Parameter Setting Baud Rate 115200 Data Bits 8 Parity Bit None Stop Bit 1 Flow Control None 8.2. Interrupt Pins Four mappable interrupt pins are available based on application specific requirements. The available modes are detailed in the following table. 8.2.1.
The nReset pin is an active-low input that resets the LNQNSM01 module MCU. It is recommended to connect a weak pull-up resistor to this pin. To prevent potential framing issues at power on, nReset should be asserted after the host controller has been powered on and initialized. 8.5. Time Synchronization Pin The time synchronization pin allows for a global clock to be used to synchronize the network rather than relying on relying on synchronization packets to maintain a network connection.
See current draw characteristics in section 6, Operating Characteristics, for information on expected power consumption. 8.7. SWD Pins SWD pins can be used for reprogramming the onboard microcontroller. It is highly recommended that all device firmware updates are issued using Lynq’s UART bootloader and official Lynq support software only. 8.8.
