HC-11 433MHz wireless RF serial UART Module CC1101

The HC-11 433MHz wireless RF serial UART module is a transceiver based on the CC1101 radio chip. It works like a wireless serial cable: data sent to its TX/RX pins comes out of a second HC-11 module, so two Arduino, ESP32 or other microcontroller boards can exchange data without wires and without a complex radio library.

HC-11 433MHz Specifications

• Radio chip: CC1101
• Frequency band: 433 MHz
• Interface: UART serial (TX, RX)
• Default baud rate: 9600 bps
• Mode: half-duplex transceiver, sends and receives
• Configuration: channel, baud rate and power set by AT commands and kept after power-off
• Range: up to about 100 m in open space, less indoors

HC-11 433MHz Applications

• Wireless serial links between two Arduino boards
• Remote sensor readings and weather stations
• Remote control of robots and small vehicles
• Replacing long serial cables in workshops and farms

What's in the Box

• 1 × HC-11 433 MHz wireless serial module

Tip: You need at least two modules for a link, set to the same channel and baud rate. Connect the module TX to the board RX and RX to TX, and share a common ground between them.
