Nano LR Click Board™

Product Code: MIKROE-4514

How Does The Nano LR Click Board™ Nano LR Click Board™ Work? The Nano LR Click Board™, as its foundation uses the EMB-LR1276S, a sub-1GHz wireless module that supports the LoRaWAN long-range wireless protocol based on the SAMR34 SiP from Embit. It offers a long-range spread spectrum communication with high interference immunity. Nano LR Click is ideal for use in various applications, such as IoT, home and building automation, wireless alarm and security systems, automated meter reading, industrial monitoring and control, and more. ​ The EMB-LR1276S can be configured as an embedded microsystem or a simple data modem for low power applications in the 868MHz and 915MHz radio bands. It is equipped with up to 256 KB of Flash and up to 40 KB of SRAM and it supports long-range and FSK modulation. The Nano LR Click Board™ communicates with MCU using the UART interface with commonly used UART RX and TX pins with the hardware flow control pins UART CTS, RTS, RI (Clear to Send, Ready to Send, and Ring Indicator).

Besides these pins, Nano LR Click has also GP1 and STAT pins, which are routed to the PWM and AN pins of the mikroBUS™ socket, respectively. STAT pin is also wired to a separate LED indicator labelled as STAT to enable quick and easy module status indication. The Nano LR Click Board™ features the U.FL antenna connector with an impedance of 50Ω, so it can be equipped with the appropriate antenna that MikroE has in its offer. The Nano LR Click Board™ is designed to work with 3.3V only. When using it with MCUs that use 5V levels for their communication, a proper level translation circuit should be used. SPECIFICATIONS Type LoRa Applications Can be used for developing highly integrated long-range IoT networks, security systems, alarm networks, and similar applications that require simple and reliable networking solutions On-board modules EMB-LR1276S - a sub-1GHz wireless module that supports the LoRaWAN long-range wireless protocol from Embit Radio Region Worldwide Key Features Low power consumption, 868MHz and 915MHz radio bands, 256 KB of Flash, up to 40 KB of SRAM, long-range and FSK modulation, and more.
