What is the name of these connectors? (XBee Radio Module)
Asked before: What exact header is this? (and others)
So as mentioned in the linked post it is these:
https://www.digikey.com/en/products/detail/digi/76002056/3481914?s=N4IgTCBcDaIOwDYAMSxIKwJAXQL5A
It appears to be obsolete though. I get some strange hits via octopart on the partnumber 76002056. It directs to the devboard and not the socket. (sortof; is that price correct?)
It seems to me that these are something properitary to digi. I would reach out directly to them. I have no idea, but they might sell them directly to you. Worth a try anyway.
