content: I noticed that SIP modules usually use these kind of connector to connect with the other boards.Does anyone know the name of this connector? And where to get them (digikey, aliexpress, etc...).Thanks in advance.

content: It looks like a simple 100 mil pitch. Will fit a solderless breadboard and female pinheader sockets. Tons of connectors with that pitch. But measure it to make sure.

content: It always bothers me that they sell these things without the leadframe. You have to go herehttps://www.ebay.ca/itm/Lead-Frame-with-Single-In-Line-SIL-Contact-2-54mm-Pitch-AMP-TE-CONNECTIVITY/362950079506?hash=item548182b412:g:Q5EAAOSwnSBedKWE

content: Quote from: Benta on July 15, 2020, 06:19:25 pmThanks for the explaination. Too bad the only place I can find them with the leadframe is ebay, and the price is... well, not comparable to digikey. I guess I'll have to improvise (unless somebody happens to find something cheaper)

content: Check the official TE channels (distributors etc.). Normally you'd buy a complete reel of these things, but we've no idea how many you need.BTW: here's the product list for selecting pitch, plating, board thickness etc.:https://www.te.com/usa-en/plp/leadframes/Y30nn.html
