Introduction

The VG2379SxxxNOS1 series wireless modules are designed around SEMTECH's high-performance SX1268 transceiver IC, offering a compact, low-power, long-range bidirectional wireless solution. The SX1268 sub-GHz transceiver is ideal for long-range wireless applications, featuring a 4.2mA active receive current optimized for battery-powered devices and an integrated high-efficiency power amplifier with up to +22 dBm output. The module supports both LoRa modulation for LPWAN scenarios and (G)FSK modulation for legacy applications, with highly configurable parameters to meet diverse requirements across industrial and consumer markets. The LoRa modulation is compatible with the technical specifications published by the LoRaWAN Alliance. Designed for use in systems compliant with radio regulations — including but not limited to Chinese regulatory requirements and ETSI EN 300 220 (434 MHz) — the module's continuous frequency coverage from 410 MHz to 810 MHz supports China's 490 MHz and 780 MHz band low-power short-range device applications. With all RF-related functions and components fully integrated, users can develop stable, reliable wireless solutions and IoT devices without in-depth knowledge of RF circuit design.
