AI-Thinker NF-01-S 2.4GHz Wireless Transceiver Module
The AI-Thinker NF-01-S is a compact 2.4GHz wireless transceiver module based on the Si24r1 chip, offering SPI interface control and data rates up to 2Mbps for low-power IoT sensor networks and remote control applications.
Features
- Ultra-compact DIP-8 package with integrated 2.4GHz PCB antenna for simplified PCB integration.
- High-speed SPI interface (up to 10MHz) enables rapid data exchange with host microcontrollers like STM32 or ESP32.
- Low power consumption with 15mA receive current and a deep shutdown mode drawing only 1.0µA.
- Robust RF performance with +7dBm max transmit power and -96dBm sensitivity at 250kbps for reliable short-range links.
- Supports multi-point and frequency-hopping communication across 126 channels to avoid interference.

The AI-Thinker NF-01-S module integrates a Si24r1 RF transceiver into a miniature DIP-8 footprint, providing a pure hardware solution for 2.4GHz ISM band communication. It operates on a wide 1.9V to 3.6V supply, typically 3.3V, making it compatible with most 3.3V microcontroller systems without requiring a level shifter.
Its architecture includes an integrated high PSRR LDO for stable operation and a smart ARQ baseband protocol engine for automatic packet handling, reducing firmware overhead. The module supports GFSK/FSK modulation and three selectable data rates (2Mbps, 1Mbps, 250kbps), allowing developers to balance between throughput and range. With a built-in PCB antenna offering approximately 2dBi gain, it is designed for cost-effective, high-volume IoT deployments like active RFID tags, wireless sensor nodes, and human-interface devices.
