NRF24L01- PA LNA Wireless Module 2.4GHz Enhanced Power Transceiver Wireless Transceiver Module 1.9-3.6V for Arduino/Raspberry Pi

Low Operating Voltage: 1.9–3.6V High Data Rate: 2Mbps (configurable to 1Mbps or 2Mbps via software), significantly reducing wireless transmission collisions due to ultra-short air transmission time. Multi-Channel: 125 frequency channels, supporting multi-point communication and frequency hopping. Compact Size: Built-in 2.4GHz antenna, ultra-small dimensions: 15×29mm (including antenna). Dimensions: 17.8mm x 12mm Weight: 1.5g The NRF24L01 is a single-chip transceiver operating in the globally available 2.4–2.5G H z ISM band. The wireless transceiver includes: Frequency generator Enhanced ShockBurst™ mode controller Power amplifier Crystal oscillator Modulator Demodulator Output power, channel selection, and protocol settings are configurable via the SPI interface. Ultra-low power consumption: Transmit mode (6dBm): 9.0 m A Receive mode: 12.3m A Even lower current in power-down and standby modes. Key Features: Low operating voltage: 1.9–3.6V High-speed data rate: 2Mbps (configurable to 1Mbps or 2Mbps), minimizing wireless collisions. 125 frequency channels, enabling multi-point and frequency-hopping communication. Ultra-compact design: Built-in 2.4 G H z antenna, dimensions 15×29mm (including antenna).

Low power consumption: Fast air transmission and startup time in acknowledgment mode drastically reduce current draw. Low application cost: Integrated RF protocol handling (e.g automatic retransmission of lost packets, auto-acknowledgment). SPI interface compatible with MCU hardware SPI or G PIO bit-banging. Internal FIFO supports high/low-speed microprocessors, enabling cost-effective M C U designs. Easy development: Fully integrated link layer simplifies development. Automatic retransmission of lost packets (retry time/count configurable via software). Auto-acknowledgment upon valid data reception (no additional programming required). Carrier sensing (fixed-frequency detection). Built-in hardware CRC and point-to-multipoint address control. Packet error counter and carrier detect for frequency hopping. Six configurable receive channels with selective activation. Standard 2.54mm-pitch pin headers for embedded applications.
