HC-11 433MHz wireless RF Serial UART Module CC1101
HC-11 433MHz Wireless RF Serial UART Module CC1101
1. RF Chipset: CC1101
2. Operating Frequency: 433 MHz
3. Communication Interface: UART
4. Communication Distance: Up to 1000m (Open Area)
5. Data Rate: Up to 500 kbps
6. Operating Voltage: 3.3V
The HC-11 is a 433MHz wireless RF serial UART module built around the CC1101 RF chipset, letting a microcontroller send and receive wireless data over a simple UART connection without handling RF protocol details directly.
It uses FSK/GFSK modulation at 433MHz, communicating with a host over UART at up to 500kbps, and connects to an external antenna via IPEX or SMA interface. Operating at 3.3V, it can transmit at up to +10dBm, reaching communication distances of up to 1000m in open-area conditions.
Rated for operation across -40°C to +85°C, this module suits wireless communication links, remote control systems, telemetry, and general IoT data transmission where line-of-sight range matters.
