Product Details
HC-11 CC1101 433MHz Wireless Transceiver RF Serial UART Module (SKU: 319335)
The HC-11 CC1101 Module is a robust and power-efficient wireless data transmission solution operating in the common 433 MHz ISM (Industrial, Scientific, and Medical) band. It is built around the CC1101 RF Transceiver chip, which is renowned for its high sensitivity and stability, enabling reliable, long-range communication for IoT and data acquisition applications.
The module is designed for ease of integration, featuring a Serial Pass-through Mode that simplifies the replacement of wired UART/TTL connections with a wireless link. The operating voltage is flexible, ranging from 3V to 6V DC, making it compatible with both 3.3V and 5V microcontrollers. Power management is a key feature, with the module drawing as little as 3.5 mA in active mode and minimizing draw to just 80μA in sleep mode. With a configurable Transmit Power up to 10 dBm and high Receiving Sensitivity (down to −112 dBm), this module is capable of achieving significant communication distances in open environments, while supporting adjustable serial baud rates from 1.2 Kbps to 115.2 Kbps.
