DreamLNK DL-RTC1101B-433M

This module is based on the TI-Chipcon CC1101 wireless transceiver IC, offering a compact, long-range, high-performance wireless transceiver solution. The chip operates primarily on dedicated national frequency bands including 315MHz, 433MHz, 868MHz, and 915MHz. It achieves a sensitivity of -114dBm, a maximum data rate of 500Kbps, and an output power adjustable from -30dBm to +10dBm via register configuration. The module integrates all RF-related functions, enabling users to develop stable and highly reliable wireless products without in-depth knowledge of RF circuit design, thereby shortening product development cycles. Two interface modes are available to support both SMT applications and through-hole soldering — horizontal or vertical — via standard 2.0mm pin headers. Its compact form factor suits portable products, and when paired with a low-power MCU, it meets the requirements of low-power systems effectively.
