I'm searching for a 4-pin connector like the one that is displayed below to connect to a device through UART. We have received a couple of connectors from the manufacturer, but we have way more units than connection wires.

The pins ar about 1 mm apart.

Any help would be appreciated.

Thank you

Edit: The distance between pin 1 and 4 looks just a little less than 4 mm when measured with a simple ruler. I'll try to do some more precise measuring later today.

    \$\begingroup\$ In case you didn't think of it: measure the distance between pin 1 and pin 4 and divide by 3... \$\endgroup\$ – Huisman Jul 29 at 11:58
  • \$\begingroup\$ if those pins are 1mm apart, your thumb is tiny. \$\endgroup\$ – Jasen Jul 29 at 12:45

    \$\begingroup\$ That is 1.27mm pitch (0.05"). I would look at Molex wire to board connectors with that pitch. \$\endgroup\$ – Peter Smith Jul 29 at 13:37
