solderless connectors for castellated edge

Question

I am looking to see if there are solderless connectors that can be used for castellated edge half holes such as the ones on this board https://www.newark.com/nordic-semiconductor/nrf52840-dongle/bluetooth-module-v5-2mbps/dp/65AC6168?ost=nrf52840+dongle&ddkey=https%3Aen-US%2FElement14_US%2Fsearch

thank you for your help

The pogo pin idea is good. You might also be able to use an IC test clip (made by Pomona or 3M) - you may need a 24 pin version to get the width you need: 3M IC test clip 3M IC test clip

There was a recent project on hackaday that might give you some inspiration: https://hackaday.com/2019/12/07/simple-pogo-programmer-for-esp8266-modules/

I was simply wondering if there was a way to temporarily connect the above dongles to breadboard without soldering anything. I was hoping some solution like a clip that could be spring loaded keeping pressure while holding multiple leads in place. Searched a bit. Did not find anything. Thought i would ask the experts. Noticed now that the link i posted might not have worked. Trying another one - https://www.newark.com/nordic-semiconductor/nrf52840-dongle/bluetooth-module-v5-2mbps/dp/65AC6168?st=nrf52840 If there are no readily available solutions, maybe a 3d printed case which would hold pins at the right place (just thinking out loud) Thanks for your reply

I haven't tried it but it should be possible to make something with pogo pins and a 3D printed jig to guide and hold things in place. If the castellations are on 0.1" centers then a prototype pcb could be used to hold the pogo pins in place. Pogo pins: Product Link Product Link
