CC1101 433MHz Wireless RF Transceiver Module Low Power Serial Communication Board With Spring Antenna For Arduino Smart Home Project

CC1101 433MHz Wireless RF Serial Communication Module

📌 Product Overview

The CC1101 low‑power wireless RF module adopts TI high‑performance CC1101 radio chip, an upgraded and pin‑compatible replacement version of CC1100 with better performance. It supports a maximum transmission rate of 500kbps with software‑configurable baud rate. The open‑air communication distance can reach 300~500 meters, and the receiving sensitivity is as low as ‑116dBm. Equipped with a nickel‑plated spring antenna, this module features high reliability and excellent cost‑performance. It is widely applied in short‑range wireless scenarios such as wireless meter reading, industrial remote control and low‑power handheld devices.

✨ Core Features

1. Operates on the license‑free 433MHz ISM frequency band
2. Supports 2‑FSK, GFSK and MSK modulation modes
3. Baud rate adjustable by software for different working conditions
4. High baud rate for fast data transmission; low baud rate for stronger anti‑interference and penetration with longer transmission range
5. Built‑in hardware CRC check and point‑to‑multipoint address control
6. Ultra‑low power consumption: RX current only 15.6mA @ 2.4Kbps, 433MHz
7. Programmable RF output power up to 10dBm
8. Wireless wake‑up function to activate MCU from sleep mode
9. Supports CCA carrier‑sensing automatic channel detection before transmission
10. Fast frequency synthesizer for flexible frequency hopping design
11. Software configurable module address for easy programming
12. Standard DIP pin header for convenient embedded connection
13. Independent 64‑byte RX / TX FIFO data buffer
