The RAK3172-8-SM-NI is a low-power LoRaWAN transceiver module based on the STM32WLE5CC chip, designed for long-range wireless data applications. It operates within the 864MHz to 868MHz frequency range and supports a supply voltage of 2V to 3.6V. The module features an SMD package measuring 15.5x15mm with an IPEX interface. It complies with LoRaWAN 1.0.3 Class A, B, and C specifications. Key electrical parameters include a current consumption of 5.22mA in receive mode and 87mA in transmit mode, with an operating temperature range of -40°C to +85°C.
Verify that the specific suffix '-8-SM-NI' corresponds to the required regional frequency band (EU868/IN865/RU864). Confirm compatibility with the host microcontroller's voltage levels and SPI/I2C interfaces. Ensure the design accommodates the SMD footprint and IPEX antenna connector requirements as specified in the official datasheet.
Select this module when a compact, low-power solution for EU or Asian regulatory bands is required. It is suitable for designs needing integrated LoRaWAN stack support without external TCXO. Compare against variants like RAK3172-9-SM-NI if North American frequencies are needed instead.
This component belongs to the WisDuo RAK3172 family of LoRa modules. It utilizes the STM32WLE5CC MCU, offering a balance of processing power and energy efficiency. The module is part of Mikroe's Click board ecosystem, specifically the LR 14 Click, facilitating rapid prototyping for cellular and LPWAN development tools.
RAK3172-9-SM-NI serves as a substitute for regions requiring 915MHz/920MHz/923MHz frequencies. Other RAK3172 variants may differ in antenna type or included components like TCXOs; verify exact pinout and RF performance before substitution.
