Digi restarts XBee Pro S2C production. Some differences need to be noted

Digi Of XBee PRO S2C Module due to the upstream supplier PA And other components are discontinued , It was once forced to stop production , Many users have to use ordinary S2C replace , Or steering XBee3 Enhanced models . however S2C Ordinary type signal is weak , And turn XBee3 You need to do some adaptation on the software , It doesn't seem very convenient . lately , Due to the tight supply chain ,XBee3 It was once difficult to grab spot resources in the market , Fortunately Digi hold XBee PRO S2C A new one PA, Re production , This gives XBee Users provide more options .

 

At present, there are three models that can be booked ：

new edition  S2C PRO model	Corresponding to the original model	Description
XBP24CZ7RIS-005	XBP24CZ7RIS-004	ZigBee, RF Pad, Surface Mount
XBP24CZ7UIS-005	XBP24CZ7UIS-004	ZigBee, U.FL, Surface Mount
XBP24CDMPIS-005	XBP24CDMPIS-004	DigiMesh, PCB Antenna, Surface Mount

It should be noted that , This is a change PA New version of the design XBee PRO S2C, There is a small difference between it and the original , It is mainly caused by circuit change , The original DIO9 Pins cannot be used . Because this pin is also a wake-up indication pin . So when doing replacement , Pay attention to whether it matches the original hardware circuit . namely , If the previous circuit used this DIO9 do GPIO Or wake-up instructions , You need to modify the circuit or modify the software to adapt .

The function of the sleep module to wake up the indicator pin can also be realized through CTS To achieve ,CTS And this wake-up indication pin is reversed , Function as . Generally in hardware design ,CTS Pins are often used , Therefore, if the original circuit has these two pin designs at the same time , Function substitution can be realized through software .

in addition , new edition XBee pro S2C Compared with the old one , I won't support it 802.15.4 agreement .

In the long run ,XBee3 replace S2C Is the trend , If the hardware circuit needs to be changed , Suggest using XBee3 replace S2C, In PetroChina A11 And other projects , Due to the interaction of different manufacturers , Some scenarios also need to be matched in software , To ensure that the original usage can be seamlessly migrated to new products .

* The estimation of range number is based on free air terrain and limited interference sources . The actual range will depend on the transmit power 、 Direction of transmitter and receiver 、 The height of the transmitting antenna 、 Height of receiving antenna 、 Weather conditions 、 The interference sources in the area and the terrain between the receiver and the transmitter （ Including indoor and outdoor structures , Like a wall 、 tree 、 building 、 Hills and mountains ） And change .
