PogoPin -pogoprobe holder

Some microcontrollers require non-permanent connections to program them, especially SMT-type models. The most common solution is using SMD test points for easy access with Pogo Pins, spring-loaded male contacts that ensure electrical continuity between the programmer and the PCB. Various protocols use 4-wire or 6-wire connections. For SPI programming an atTiny microcontroller, you need 2 power contacts and 4 signal contacts.

You can build your own Pogo Pin setup or purchase one like this (not affiliated): https://www.tindie.com/products/electronutlabs/pogoprog-model-b-pogo-pin-programmer-swd-2-pack/. The Pogo Probe has a 2.54mm pitch, making it easy to handle. I designed a 2x3 contact for the PCB, so I needed to place 2 Pogo Probes side-by-side and created this holder to keep the pogo pins aligned while programming the microcontroller.
