LR 5 Click is a compact add-on board that contains a long-range transceiver. This board features the 32001409, RF technology-based SRD transceiver, which operates at a frequency of 915MHz from Mipot. Thanks to the spread spectrum modulation feature, as well as the low power consumption, it is capable of achieving long-range communication, immune to interferences. It features a complete long-range stack onboard; it implements physical, network, and MAC layers, allowing for easy operation via the UART interface. This Click board™ offers an easy and reliable solution for developing highly integrated long-range IoT networks, security systems, alarm networks, and similar applications that require simple and reliable networking solutions.

LR 5 Click is supported by a mikroSDK compliant library, which includes functions that simplify software development.

NOTE: The 32001409 module is certified for American region.

LR 5 Click as its foundation uses the 32001409, a low-power long-range RF technology-based transceiver module from Mipot. It offers a long-range spread spectrum communication with high interference immunity. The network is implemented as a star topology, where endpoints work in duty cycle mode, significantly reducing the overall power consumption. This Click board™ features an embedded LoRaWAN Class A and Class C compliant stack offering an easy and reliable solution for developing low-power, highly integrated IoT networks, security systems, alarm networks, and similar applications that require simple and reliable networking solutions.

This Click board™ can be configured to work as either END or Controller NODE, by using simple AT commands. While working as the Controller NODE, the Click board™ can use a set of controller-specific commands, such as the pairing command. This command will add the end node which requested pairing, to the controller network table. While working as the END NODE, LR 5 Click can issue peripheral specific commands/requests, such as the pairing request command, which will allow that end node to be paired with the controller.

LR 5 Click communicates with MCU using the UART interface with commonly used UART RX and TX pins at data rates up to 115200bps for the data transfer. In addition to these features, the 32001409 also uses several GPIO pins connected to the mikroBUS™ socket. The WK pin routed on the CS pin of the mikroBUS™ represents the Wake-up function used for waking up the device, while the RST pin on the mikroBUS™ socket can perform Hardware Reset function by putting this pin in a logic low state. This Click board™ also has an indicator routed on the INT pin of the mikroBUS ™ socket, which will provide the user with feedback after a successfully received package and verified checksum.

LR 5 Click features the SMA antenna connector with an impedance of 50Ω, so it can be equipped with the appropriate antenna.

This Click board™ can operate with both 3.3V and 5V logic voltage levels selected via the VCC SEL jumper. A proper logic voltage level conversion is performed by the TXB0106 voltage level shifter, while the LDO ensures that recommended values power the module. This allows for both 3.3V and 5V capable MCUs to use the UART communication lines properly. However, the Click board™ comes equipped with a library containing easy-to-use functions and an example code that can be used, as a reference, for further development.
