Using original NRF24L01 manufactured modules have been tested professional equipment!
(1) 2.4Ghz global open ISM band license-free use
(2) The maximum operating speed of 2Mbps; anti-jamming;; efficient GFSK modulation is particularly suitable for industrial control applications
(3) 125 channels, multi-point communication and frequency hopping to meet the communication needs
(4) built-in hardware CRC, FEC error detection and multipoint communication address control
(5) Low Voltage 1.9 ~ 3.6V work, low power consumption, low emission current of just under 7mA Power down mode state only 1uA
(6) PCB2.4Ghz antenna, small size about 24X24mm
(Not including the antenna)
(7) The module can be software set address, only received local address will output data (provide interrupt instructions), can be directly connected to a variety of MCU, software programming is very convenient
(8) 2.54mm standard DIP spacing interfaces for embedded applications
Note: This module needs 3.3V supply available, 3.3V regulator chip shop 5V-3.3V Buck
Second, the performance parameters
(1) Size: 34mm X 17mm X 1mm
(2) open to the maximum distance 80 m
