ASR6601 Chip Based LoRaWan Module / LoRa Relay Module / LoRaWAN Node Module
The DL-A6601-B module is a wireless transceiver module based on the ASR6601 chipset solution. The ASR6601 integrates a low-power Cortex-M4 core (48 MHz) and LoRa modulation technology, offering higher integration than traditional SPI + MCU solutions, resulting in a more compact form factor.
It supports a maximum output power of 22 dBm, significantly improving link budget, communication quality, and range. It also features a temperature-compensated crystal oscillator (TCXO), which solves frequency deviation issues caused by prolonged transmission heat or extreme temperature variations. Even at room temperature, it achieves narrower bandwidth, higher sensitivity, and more stable communication.For the RF section, the module employs next-generation LoRa modulation, which outperforms traditional modulationmethods in power efficiency, sensitivity, and low-power performance. The chip achieves an industry-leading sensitivity of -148 dBm and demonstrates strong anti-interference and blockingresistance.Additionally, the module consumes only 3.5 µA in sleep mode and 7 mA during wireless reception (including MCU operation), making it ideal for long-range communication and battery-powered applications.
The RF circuitry has been professionally matched and optimized, ensuring high power performance while maintaining a compact size. Users only need to integrate the module onto their mainboard, attach an antenna, and no additional RF matching is required, significantly shortening development cycles.
Main Features:
✅ Single-chip ASR6601 (Cortex-M4 + LoRa) – Higher integration, compact size
✅ Up to +22 dBm output – Extended range & better link budget
✅ TCXO for stable frequency – Prevents drift in extreme temperatures
✅ Ultra-low power – 3.5 µA sleep, 7 mA RX (MCU active)
✅ -148 dBm sensitivity – Superior signal reception in noisy environments
✅ Pre-tuned RF design – No external matching needed, faster time-to-market
✅ Ideal for IoT, smart metering, asset tracking, and industrial sensors where long-range, low-power, and reliability are critical.
