Overview
The Monarch Adapter Click Board™ is used to connect compatible Monarch Go LTE-M modems from Sequans to your development board or prototype device. This Click adapter provides a connection to the cloud server with AT commands. The Monarch Go LTE-M modem component with embedded antenna is perfectly suited for a broad range of IoT applications, including telemetry, vending machines, agriculture sensor applications, asset and transportation trackers, hardware tools, and home security monitoring applications.
The Monarch Adapter Click Board™ is supported by a mikroSDK compliant library, which includes functions that simplify software development. This Click Board™ comes as a fully tested product, ready to be used on a system equipped with the mikroBUS™ socket.
Monarch GO and Monarch GO-GPS are certified for use on the Verizon network (LTE band 13) with roadmap for global band support. Monarch module is not delivered as part of the Click board package. For more information about module features please read Monarch GO module specification.
How Does The Monarch Adapter Click Board™ Work?
The Monarch Adapter Click Board™ is intended to help customers to successfully integrate and test their application based on Monarch Go. This Click adapter communication with your device through a serial UART interface and can exchange data with a cloud server using Verizon LTE network. The UART and GPIO pins of Monarch Go LTE-M modem is connected to one side of the level shifter, while the other side (Shifted) is connected to the respective mikroBUS™ UART and GPIO pins. However, the Monarch Go LTE-M modem series module is designed as the traditional DCE device (Data Communication Equipment) offering the full UART pin count, including the hardware flow control pins (CTS, RTS). These pins are routed to the mikroBUS™ CS (RTS) and the INT pin (CTS) and can be used in the MCU software if the hardware flow control is needed.
Digital sections of the Monarch Go LTE-M modem are internally supplied by 1.8V, so it is necessary to condition the communication bus lines which connect the host MCU with the module. The Monarch Adapter Click provide internal 1.8V via BH18PB1WHFV-TR LDO regulator from Rohm Semiconductor, output from its internal LDO regulator, providing a needed reference voltage for one side of the TXB0106, a 6bit bidirectional level shifting and voltage translator with automatic direction sensing, from Texas Instruments. The reference voltage for the other side of the level shifter is taken from the onboard SMD jumper, labelled as I/O Level This jumper is used to select between 3.3V and 5V from the mikroBUS™, depending on the used MCU type and its logic voltage level requirements.

Software Support
We provide a library for the Monarch Adapter Click Board™ on our LibStock page, as well as a demo application (example), developed using MikroElektronika compilers. The demo can run on all the main MikroElektronika development boards.
Library Description
The library contains basic functions for working with the Monarch Adapter Click Board™.
Key Functions
void monarch_send_command( uint8_t *cmd_buf, uint8_t len )- Send command function
Example Description
The application is composed of three sections :
- System Initialization - Initializes UART modules and all required GPIO modules
- Application Initialization - Initializes driver inti and send basic commands.
- Application Task - Sends ATI1 command every 5000 ms.
void application_task ( )
{
monarch_send_command( &MONARCH_CMD_ATI1[ 0 ], 4 );
Delay_ms( 5000 );
}
The full application code, and ready to use projects can be found on our LibStock page.
Other mikroE Libraries used in the example:
- UART library
- Conversions Library
Additional Notes and Information
Depending on the development board you are using, you may need USB UART click, USB UART 2 click or RS232 click to connect to your PC, for development systems with no UART to USB interface available on the board. The terminal available in all MikroElektronika compilers, or any other terminal application of your choice, can be used to read the message.
MIKROSDK
The Monarch Adapter Click Board™ is supported with mikroSDK - MikroElektronika Software Development Kit. To ensure proper operation of mikroSDK compliant Click board™ demo applications, mikroSDK should be downloaded from the LibStock and installed for the compiler you are using.
