A few weeks ago, we covered the 2x5 0.05" pitch SWD sockets https://blog.adafruit.com/2023/08/14/the-great-search-2x5-0-05-jtag-swd-connector-and-cable-thegreatsearch-digikey-adafruit-digikey-adafruit/ that we have on many of our dev boards. Those connectors are standard issues for programming Arm Cortex chips with SWD or other devices with JTAG.

However, sometimes you don't need or want the bulk of a chonky IDC connector - and only some customers will need to field reprogram or debug. But just having pogo pads is more accessible to connect to if you have the specific jig.

We'll cover two solutions for 'press fit' programming: Tag Connect standard https://www.tag-connect.com/ and another exciting option we spotted on Twitter, now called X, from arturo182 and abhinav_937 https://twitter.com/arturo182/status/1701760589419208995 , is using a SKEDD REDFIT cable. https://www.digikey.com/short/t1hhf3qj
