Here we have some right-angle headers with 40x3 pins. They are break away and will take a bit of effort to break this beast where you need it to break. That being said, if you need a big header like this, it's easy enough to break it where you need. The pins are spaced at 0.1" and there are 3 rows of 40 pins. These work well in the UAV boards listed below. https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2010-08-17 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2015-07-31 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2015-09-01 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2015-12-30 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-01-14 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-11-25 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-11-28 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-11-29 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-12-09 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-12-13 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2016-12-26 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2017-01-10 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2017-08-04 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2017-08-12 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2017-11-24 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2017-11-28 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2018-05-05 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2018-11-21 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2018-11-27 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2019-03-01 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2019-03-19 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2022-10-24 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2025-01-19 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2025-04-11 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2025-04-14 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2026-08-08 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2026-08-10 https://elecena.pl/product/1156004/right-angle-header-male-pth-0-1in-3x40-pin 2026-08-18
