These jumpers were priceless if you sneezed and lost one. https://elecena.pl/product/786632/jumper-2-pin 2009-01-10 https://elecena.pl/product/786632/jumper-2-pin 2016-11-25 https://elecena.pl/product/786632/jumper-2-pin 2016-11-28 https://elecena.pl/product/786632/jumper-2-pin 2016-11-29 https://elecena.pl/product/786632/jumper-2-pin 2016-12-09 https://elecena.pl/product/786632/jumper-2-pin 2016-12-13 https://elecena.pl/product/786632/jumper-2-pin 2017-11-24 https://elecena.pl/product/786632/jumper-2-pin 2017-11-28 https://elecena.pl/product/786632/jumper-2-pin 2018-05-05 https://elecena.pl/product/786632/jumper-2-pin 2018-11-21 https://elecena.pl/product/786632/jumper-2-pin 2018-11-27 https://elecena.pl/product/786632/jumper-2-pin 2022-02-22 https://elecena.pl/product/786632/jumper-2-pin 2025-04-14
