Description
nRF24L01+RF2401C PA LNA 2.4GHz Wireless RF Transceiver Module Long Distance Transparent Transmission Anti-interference
Product Description
2.4GHz 100mW, high speed (the highest air rate can reach 2Mbps), high stability, industrial-grade wireless transceiver integrated digital transmission module. The module adopts NORDIC original nRF24L01 P radio frequency chip and RFX2401C power amplifier chip, built-in LNA, receiving sensitivity increased by 10dBm, working in 2.4GHz~2.5GHz ISM frequency band, with metal shield, strong anti-interference performance! This module has sufficient transmit power , The spectral characteristics are very good, the harmonics are very small, the channel crosstalk is small, and the volume is small. All Murata original B files are a model of industrial standards.
Interface type: SPI RF chip: nRF24L01+ Center frequency: 2.4~2.525GHz (2.4GHz) Maximum power: 100mW Communication distance: 2000 meters

Installation Instructions
Pin description
1: GND, ground wire, connected to the power reference ground 2: VCC, power supply, range 1.8-3.6V, recommended 3.3V, recommended external ceramic filter capacitor 3: CE, input, module control pin, please refer to nRF24L01P Datasheet 4: CSN, input, module chip select pin, used to start a SPI communication 5: SCK, input, module SPI bus clock 6: MOSI, input, module SPI data input pin 7: MISO, output, module SPI data output pin|pin 8: IRQ, output, module interrupt signal output, active low
Notes: 1. CE can be connected to the high level for a long time, but the module must first be set to POWER DOWN mode when writing the register. It is recommended to connect CE to the IO port of the MCU. 2. IRQ can be disconnected, and the interrupt status can be obtained by SPI query. But it is recommended to use the external interrupt of the microcontroller. 3. Pay attention to good grounding, large-area paving, and small power supply ripple. Filter capacitors should be added and placed as close as possible to the VCC and GND pins of the module.
