HOW DOES IT WORK?

LR 10 Click is based on the Wio-E5, a LoRa wireless module from Seeed Technology, renowned for its minimal power draw and compactness. This powerhouse module incorporates the STM32WLE5JC system-level package chip and the SX126X LoRa® chip for stellar performance alongside an Arm® Cortex® M4 MCU that ensures ultra-low power consumption. Designed primarily for IoT applications requiring minimal power and extended range—such as wireless sensor networks, remote meter reading, and other low-power, wide-area network scenarios - the Wio-E5 stands out as a versatile solution for many IoT needs.

As mentioned, the Wio-E5 module integrates the STM32WLE5JC. This chip excels in various IoT applications thanks to its support for multi-mode operations, including (G)FSK and LoRa®, with bandwidth options ranging from 62.5kHz to 500kHz in LoRa® mode. It is characterized by a maximum RF input power of +10dBm, ensuring robust signal strength. The device operates seamlessly across a broad frequency range of 868 to 928MHz, accommodating a wide spectrum of wireless communication needs. With an ability to deliver an output power of up to 22dBm, it ensures extensive coverage and reliable transmission across its operational frequency range. Furthermore, the board achieves a peak sensitivity of -137.5dBm, guaranteeing consistent and dependable communication capabilities, even under demanding environmental conditions.

This Click board offers a rich selection of available interfaces to communicate with the host MCU, such as UART, I2C, and SPI, catering to diverse application needs. It simplifies the design of LoRaWAN® nodes through embedded global LoRaWAN® protocol support and an AT command set achieved by UART and reset RST pin integration. Firmware upgrades are also possible via the UART interface in a Boot mode, triggered by the BOOT button, allowing for easy programming and software development leveraging the onboard MCU's capabilities through the SWD interface pins on the board's side.

LR 10 Click also features the SMA antenna connector with an impedance of 50Ω, compatible with various antennas available from MIKROE, like the Rubber Antenna 868MHz, to enhance its connectivity.

This Click board™ can be operated only with a 3.3V logic voltage level. The board must perform appropriate logic voltage level conversion before using MCUs with different logic levels. Also, it comes equipped with a library containing functions and an example code that can be used as a reference for further development.
