Overview
Delay block is an open-source printed circuit board by restelli, from the restelli/pulse_delayers repository on GitHub. It is a 2-layer board of 55.4 × 81.8 mm with 51 parts on 39 nets, routed with 250 tracks and 15 vias.
It is built around the DS1023S-500+T&R, DS1100Z-500+ and DS1110S-500+, with the LTC6994CS6-2#TRMPBF among its other parts. Its parts include 34 resistors, 9 connectors, 4 capacitors and 4 ICs.

This is a PCB to test four delay chips. I put it together in a couple of hours for a dirty test, but if further refined it could become a handy lab tool. (Note that the SMA and power connectors are intentionally placed on the wrong side of the board)

Questions
How big is the Delay block PCB?
It measures 55.4 × 81.8 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Delay block use?
51 parts, built around the DS1023S-500+T&R, DS1100Z-500+, DS1110S-500+ and LTC6994CS6-2#TRMPBF. The full list of its parts is on this page, with links to each part's symbol and footprint where PCBKit's library has them.
Where can I download the Delay block KiCad files?
From the restelli/pulse_delayers repository on GitHub, at the commit this page was made from: the board is delay_block.kicad_pcb and its schematic delay_block.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Delay block design in my own project?
Its repository states no licence, so its author keeps all rights: ask restelli before reusing the design.
