I have the following connectors on a USB dongle (the ones on the left of DEBUG):

enter image description here

They are tiny (I put the dongle on an Arduino to show the differences with the typical ones I know)

Are they standard? And if so - is there a specific name for them which I could use to search a connector? (I clumsily tried to solder some cables instead but this is out of my soldering league)

    \$\begingroup\$ It looks like a pretty standard 0.05" pitch pin header. I use them daily. These may help ... \$\endgroup\$

  • \$\begingroup\$ There are also 2mm pitch and 1mm pitch pin headers. \$\endgroup\$

    \$\begingroup\$ What is your goal here? If you read the manual for the TI CC-Debugger programmer that is intended to plug in there, you'll see listed in the package contents "1 x 10-pin flat cable with 2x5 1.27 mm connector". If you are designing your own product consider putting the few signals actually required on something compatible with a spring pin fixture and not just manual cable connection. \$\endgroup\$

  • \$\begingroup\$ They look like normal "header pins" or "dupont pins" to me. They are pretty standard across electronics like the Arduino, Pi, etc. You can buy male/female ones and cables too - at a low cost. Just search header/dupont cables on eBay or wherever. \$\endgroup\$

  • \$\begingroup\$ @ChrisStratton: I just need to reflash the dongle via an Arduino (koenkk.github.io/zigbee2mqtt/information/…) and the physical connection is on the way. \$\endgroup\$

Those are the 1.27mm pinheaders, often used for ARM Cortex SWD debug connectors. However, this is a TI CC2531F256 wireless SoC.

Samtec has one with small shroud under sku: FTSH-105-01-L-DV-K.

(Other vendors also sell parts similar to this, but not with a 3D part tool as Samtec website)

    \$\begingroup\$ Sort of. It does indeed look like a similar connector. But this is not SWD as the MCU pictured has an 8051 core not an ARM core. So one might be able to buy a "straight through" cable adapter from the small pitch to a larger one intended for ARM and use that, but something with ARM-specific wiring would probably not work. \$\endgroup\$
