Wireless module for NRF24L01:
â‘ MODULE FEATURES:
1>.I2C (TWI) communication protocolis used, which simplifies the NRF24L01 communication processgreatly,thus usersno need to understandthetedious communication processof NRF24L01,itimprovestheefficiency ofproject development Immenselyby this way.
2>. Each modulewill beasa slave ofI2C (TWI).(address 35)
3>. Module isin a small frame with length 73mm,width 22mm.
4>. Smooth bidirectional communicationand nodiscernablethe slave or master.
5>. Maximum transmissive distance can reach 70m(Justforreference)
6>. Wireless correspondingchipisreliable NRF24L01communication protocol,it will reduce data lost.
7>. I2C/TWI protocol simplifies the communication linesgreatly.
8>. Compatible with arduinoperfectly.
Robot control, remote control.,Information collectionandetc.
Note: The wireless communications mayresult inradiation, so it is not recommended for life protectionarea.
â‘˘. RELEVANT PARAMETERS:
Operating voltage: 5V.(No short-circuit protection,so you must be careful with polarity connection when you use.)
Holdtimeof module receiving data :more than 2S
Holdtimeof module transmitting data:more than 300s
Transfer rate:50Byte/S (theoretical value)
I2C/TWI Address:0x47 (decimal 35)
NRF24L01 Address:0x34, 0x43, 0x10, 0x10, 0x01 (from low to high)
Holdtimeof module transmitting data means when the module (TWI slave) receives data sent frommaster, it will transmit the date to another module, and thenit will wait to receive another responsed signal of that module,if there is no responsed signal after a while,the module will send the data again,repeated sending times multiply waiting time is the hold time.
Maximum operating speeds up to 2Mbps, GFSK modulation efficiency, Anti-interference ability, Particularly suitable for industrial control applications.
125 Channels, Multi-point communication and frequency hopping to meet the communication needs
Built-in hardware CRC error detection, Multipoint communication address control.
Low-power 1.9 ~ 3.6V, only 1uA on Power down mode
Built-in 2.4Ghz antenna
Available software to set the address, only received local Address when output data(Provide interrupt instruction), can be directly connected to a variety of microcontrollers, Software programming is very convenient.
Built-in voltage regulator
Standard DIP Pitch Interface for embedded applications
