A low-cost sub-1 GHz RF transceiver module based on the Texas Instruments CC1101 IC, designed for low-power wireless communication. Pre-configured for 433 MHz operation, it is well suited for ISM and Short Range Device (SRD) applications with a transmission range of 300–500 metres depending on environment and baud rate.
The CC1101 supports multiple modulation schemes and data rates up to 500 kbps, with built-in CRC error detection, hardware address filtering, and separate 64-byte TX/RX FIFOs. The module uses a standard 2.0 mm DIP pitch interface for easy integration into embedded projects.
Key Features
- CC1101 Transceiver IC – TI sub-1 GHz RF transceiver with proven reliability
- 433 MHz Operation – Pre-configured for the 433 MHz ISM band; programmable for 300–348, 387–464, and 779–928 MHz bands
- Multiple Modulation Modes – Supports 2-FSK, GFSK, and MSK modulation
- Up to 500 kbps Data Rate – Software-configurable baud rate, power, and frequency
- Programmable Output Power – Up to +10 dBm maximum output
- High Sensitivity – Better than −110 dBm at 1.2 kbps (0.1% packet error rate)
- Low Current Consumption – 15.6 mA in receive mode (2.4 kbps, 433 MHz)

Jargon buster
Plain-language definitions for the technical terms used above.
- baud
- Baud is the signalling rate of a serial connection, often used as the speed setting for UART communication. Matching the baud rate matters because both connected devices must use the same setting for readable data.
- FIFO
- FIFO stands for "first in, first out", a way of handling stored items so the oldest one is read out first, like a queue. In electronics a FIFO is usually a small buffer that temporarily holds data, such as sensor samples or serial bytes, so a processor can collect it in batches instead of reading continuously.
- IoT
- Short for Internet of Things, meaning physical devices that connect to networks or the internet to send data or be controlled remotely. It matters if you want projects such as connected sensors, remote controls or classroom data-logging activities.
- RF
- RF means radio frequency, referring to signals used for wireless communication and other high-frequency electronics. A low-noise, stable power supply is important for RF circuits because power noise can affect signal quality and measurements.
- RX
- RX means receive, usually showing data being received by the board. An RX indicator LED can help with troubleshooting USB or serial communication.
- SPI
- A fast serial communication bus often used for displays, memory cards, and sensors. It matters because SPI devices need specific pins for clock and data, plus a separate chip-select line for each device.
- TX
- TX means transmit, usually showing data being sent from the board. A TX indicator LED can help you see when the board is communicating or uploading code.
