Description
The Ai-Thinker Si24R1 Wireless Module is a high-performance, cost-effective 2.4GHz RF transceiver designed for low-power wireless data communication. Fully pin-to-pin and register-compatible with the industry-standard Nordic nRF24L01+, the Si24R1 serves as a seamless “drop-in” replacement. It is engineered with an integrated Enhanced ShockBurst™ protocol engine, which offloads complex packet handling tasks from your microcontroller to the module itself, ensuring reliable communication with minimal software overhead.
Key Features
- Enhanced RF Performance: Delivers a maximum transmit power of +7dBm, providing a more stable link and longer range compared to standard 0dBm modules.
- Ultra-Low Power consumption: Features a deep Shutdown Mode (1μA) and a fast-waking Standby Mode (15μA), making it ideal for battery-operated IoT sensors.
- Wide Voltage Compatibility: While it operates on 1.9V–3.6V, its digital I/O pins are 5V tolerant (up to 5.25V), allowing direct connection to 5V microcontrollers like Arduino without external level shifters.
- Multi-Point Networking: Supports up to 6 data pipes (MultiCeiver™), allowing a single receiver to collect data from up to six transmitters simultaneously.
- Hardware ARQ Engine: Automatically handles packet assembly, CRC error detection, and automatic retransmission of lost data.
