{"product_id":"rak3172","title":"RAK3172 LoRa module — STM32WLE5CC, 868\/915MHz, UART\/SPI\/I2C, AT commands, ultra-low power, SMD","description":"\u003cp\u003eThe RAK3172 is a compact, ultra-low-power LoRa\/LoRaWAN module from RAKwireless, built around the STMicroelectronics STM32WLE5CC SoC — a single-chip solution integrating an Arm Cortex-M4 processor with a sub-GHz radio transceiver. It supports LoRaWAN Class A, B, and C operation and is controlled via a simple AT command interface over UART, making it straightforward to integrate into any microcontroller-based IoT design without requiring deep RF expertise.\u003c\/p\u003e\u003cp\u003eOperating in the 863–928MHz frequency range, the RAK3172 covers the EU868, US915, AU915, AS923, IN865, and KR920 LoRaWAN bands, making it suitable for global IoT deployments. Its ultra-low sleep current (approximately 1.69μA) makes it ideal for battery-powered sensor nodes requiring years of operation on a single cell.\u003c\/p\u003e\u003cp\u003e\u003cstrong\u003eKey Specifications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003ePart number: RAK3172\u003c\/li\u003e\n\u003cli\u003eCore: STM32WLE5CC (Arm Cortex-M4 + sub-GHz radio SoC)\u003c\/li\u003e\n\u003cli\u003eFrequency range: 863–928MHz (EU868, US915, AU915, AS923, IN865, KR920)\u003c\/li\u003e\n\u003cli\u003eModulation: LoRa, (G)FSK\u003c\/li\u003e\n\u003cli\u003eLoRaWAN class: A, B, C\u003c\/li\u003e\n\u003cli\u003eTX power: up to +22dBm\u003c\/li\u003e\n\u003cli\u003eReceiver sensitivity: −148dBm (SF12, 125kHz BW)\u003c\/li\u003e\n\u003cli\u003eInterface: UART (AT commands), SPI, I2C, GPIO\u003c\/li\u003e\n\u003cli\u003eSleep current: ~1.69μA\u003c\/li\u003e\n\u003cli\u003eSupply voltage: 2.0–3.6V\u003c\/li\u003e\n\u003cli\u003ePackage: SMD stamp-hole module\u003c\/li\u003e\n\u003cli\u003eDimensions: 15 × 15.5 × 3.5mm\u003c\/li\u003e\n\u003cli\u003eCertifications: CE, FCC, ISEDC, RCM, KC\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eKey Features:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003e\n\u003cstrong\u003eSTM32WLE5CC SoC\u003c\/strong\u003e — integrated Cortex-M4 + LoRa radio; no external MCU required for standalone operation\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eAT command interface\u003c\/strong\u003e — simple UART control from any host MCU; no LoRa stack expertise needed\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eLoRaWAN Class A\/B\/C\u003c\/strong\u003e — full LoRaWAN stack support for network-connected IoT applications\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003eUltra-low sleep current (~1.69μA)\u003c\/strong\u003e — years of battery life for remote sensor nodes\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e+22dBm TX power\u003c\/strong\u003e — long-range communication up to several kilometres in open environments\u003c\/li\u003e\n\u003cli\u003e\n\u003cstrong\u003e−148dBm sensitivity\u003c\/strong\u003e — excellent link budget for deep indoor and underground deployments\u003c\/li\u003e\n\u003cli\u003eGlobal frequency support — single module covers EU, US, AU, AS, IN, KR LoRaWAN bands\u003c\/li\u003e\n\u003cli\u003eSMD stamp-hole footprint — easy PCB integration with reflow soldering\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eApplications:\u003c\/strong\u003e\u003c\/p\u003e\u003cul\u003e\n\u003cli\u003eLoRaWAN IoT sensor nodes (temperature, humidity, GPS, soil moisture)\u003c\/li\u003e\n\u003cli\u003eSmart agriculture and precision farming\u003c\/li\u003e\n\u003cli\u003eIndustrial asset tracking and monitoring\u003c\/li\u003e\n\u003cli\u003eSmart metering (water, gas, electricity)\u003c\/li\u003e\n\u003cli\u003eBuilding automation and smart city infrastructure\u003c\/li\u003e\n\u003cli\u003eLong-range wireless data logging\u003c\/li\u003e\n\u003c\/ul\u003e\u003cp\u003e\u003cstrong\u003eNote:\u003c\/strong\u003e The RAK3172 operates at 2.0–3.6V — a 3.3V regulated supply is recommended.
