Vollgo VGdd79S868N0S1

The VGdd79SxxxNOS1 series wireless modules are designed around SEMTECH's LLCC68 high-performance wireless transceiver chip, offering a compact, low-power, long-range bidirectional wireless transceiver solution. The LLCC68 sub-GHz wireless transceiver is ideal for long-range wireless applications, with an active receive current consumption of only 4.2mA, specifically designed for battery-powered applications. The module features a built-in high-efficiency power amplifier capable of up to +22 dBm output, supporting LoRa modulation for LPWAN use cases and (G)FSK modulation for legacy use cases, with highly configurable parameters to meet the diverse requirements of industrial and consumer applications. The LoRa modulation is compatible with the technical specifications published by the LoRa Alliance. This wireless module is suitable for systems complying with radio regulations including ETSI EN 300 220, FCC CFR 47 Part 15, Chinese regulatory requirements, and Japan ARIB T-108. The wireless transceiver supports continuous frequency coverage from 150 MHz to 960 MHz, covering all major sub-GHz ISM bands worldwide. The module integrates all RF-related functions and components, enabling users to develop stable, highly reliable wireless solutions and IoT devices without in-depth knowledge of RF circuit design.
