Dear All,

I like to design PCB for Wireless Transmitter Module (ST-TX02-ASK - 433MHZ). It has 4 pins (GND, DATAIN, +VCC and ANTENNA). Should I use 4 individual connectors on PCB and spacing between pins based on Datasheet? Or is there any ready made pin diagram (as like PIC pin diagram) to place it on PCB?

Thanks.

For your Information, I am using ExpressPCB software for designing PCB. Any other best software available for designing PCB?

thanks

you ask about footprint of wireless module , first you must search for footprints libraries and compare the dimension of the one you found by the real dimension on the data sheet module (footprint) if it the same use it . if you not found , you must create footprint for your module. about software for PCB you can use orcad or Proteus. Proteus is easy to learn quickly
 
Depends on how you design. If your wireless transmitter is built together with other circuits, there's no connector for GND and Vcc of course. Be sure to control the impedance well with uniform ground below.
 

Thanks to both of you for your help. I didn't find wireless module foot print in library they provided. What should I do?
 

I don't really know what's the module you are using. For me, usually I don't really directly use the footprint provided by the manufacturer. I usually do a round of discussion with our assembly and fab side for the feasibility of the footprint provided by the manufacturer. Does it fit our design rules and constraints? Will it cause error to assembly? Some of the footprint provided by the manufacturers are too loose for low density board which is somewhat unnecessary.

In short, you just have to create each and every of your new footprint, at least verify it.
 
OK. Thanks for the help provided.

Hi speedEC,

Did you find a solution to this problem. I am trying to do the same thing. If you have made the footprint for expresspcb can you please share it with me
 

Sorry ganeshmirajkar for delayed reply. I could not able to use Internet during that period because of my system problem. Ok. I come to the point. I have gone thru' various PCB softwares like ExpressPCB, PCB123(Sunstone), Eagle, OrCAD and finally stopped at KiCAD PCB software. Currently I am using only KiCAD PCB for the reason of no restrictions on layers and size. No evaluation, no trial & no fee. It looks great for me. If you require any help pl PM me.

Ok. Thanks. Actually I went forward with making my own footprint for ASK tx and RX. Thanks.
