Frequently Asked Questions
Does the RAK3172-SiP support the Indian IN865 frequency band?
Yes. The RAK3172-SiP supports the IN865 (865-867 MHz) band, making it fully compliant for LoRaWAN deployments across India.
What is the difference between RAK3172 and RAK3172-SiP?
The RAK3172 is a module with a standard LGA package, while the RAK3172-SiP is a System-in-Package that integrates additional passives and the crystal oscillator internally, resulting in a smaller footprint and simplified PCB design.
Can I program the STM32WLE5 directly on this module?
Yes. You can develop custom firmware using STM32CubeIDE or use RAKwireless's RUI3 (RAK Unified Interface) API for faster development with built-in LoRaWAN stack support.
What antenna do I need?
You need an external 868/915 MHz antenna connected via your PCB design. Chip antennas, PCB trace antennas, or U.FL-connected external antennas are all viable options depending on your enclosure and range requirements.
How long can it run on battery?
With deep sleep current consumption in the low microamp range, the RAK3172-SiP can run for years on a single coin cell or small lithium battery in typical Class A LoRaWAN sensor applications with periodic transmissions.
Is this module suitable for production-scale deployment?
Absolutely. The RAK3172-SiP is designed for mass production with its compact SiP form factor, reflow-solderable package, and industrial temperature rating. Contact The Tech Depot for volume pricing and availability in India.
