In previous designs, I’ve used socketed XBee modules. This has been nice in that when I need to change a radio’s configuration, I can pull it from the circuit and use the XCTU software with a Digi prototype/IO board to modify the radio. But I am moving to using SMT variants, particularly the XBee Pro SX, where I will not be able to simply pop the radio out of it’s socket to put it in a programmer.
I am looking for a reference of what pins are critical for the XCTU and XBIB boards such that I can do my design/layout in a way that I could connect the SMT radio module to a external programmer (controlled by XCTU) while it’s still in my circuit.
I humbly request that if anyone knows of such a reference, that I be directed towards it. And if there’s not such a reference already, an article to that effect would be very appreciated.
