User's Manual
Introduction:
(1) Use 2.4 GHz global open ISM band free license
(2) The highest working rate 2Mbps, efficient GFSK modulation, anti-interference ability,
especially for industrial control occasions
(3) The built-in hardware CRC error detection and point to multipoint communication control.
(4) Low power 1.9 - 3.6V, standby mode state is 22uA; power down mode is 900nA
(5) Built in 2.4Ghz antenna, compact size
(6) The module can set up the address only when receiving the address of the machine to output
data (provide interrupt instructions), can directly take a variety of microcontroller, software
programming is very convenient
(7) Built in specialized regulator circuit, using various power supply including DC/DC switch power
supply have good communication effect
(8) Standard DIP spacing interface, easy for embedded applications
(9) Automatic packet handling, Auto packet transaction handling, With the optional built-in
package response mechanism, greatly reducing the packet loss rate.
(10) With the SC51 series microcontroller P0 port, the need to add 10K on the pull resistor, and
the rest of the port connection do not need.
(11) Other series MCU. If it is 5V, please refer to the series microcontroller IO export output
current size, if exceed 10mA and need to the series resistance divider, otherwise easy to burn
module! If is a 3.3V can direct and rf2401 module IO port line connection. Such as AVR series
microcontroller if it is 5V, the general series of resistance 2K.
Typical interface circuit:
interface Introduction:
(1) the range of the VCC pin is between 1.9V~3.6V and cannot be outside of the range,
Over 3.6V will burn the module. Recommended voltage around 3.3V.
(2) except for power VCC and ground, the rest of the foot can be directly and ordinary 5V
microcontroller IO port directly connected without level conversion. Of course, about 3V
microcontroller more applicable.
(3) the hardware above no SPI microcontroller can also control this module, with ordinary
microcontroller IO mouth simulation SPI no real serial port intervention, just ordinary single-chip
IO port can, of course, with the serial port can also.
