About the CACKLE-Passive-Endcap PCB
CACKLE-Passive-Endcap is an open source PCB design by techy-robot, published on GitHub under the CC-BY-NC-4.0 license. It is a 2-layer board measuring 45 × 5 mm, with 10 components from 4 distinct parts.
By type, the board carries 9 connectors and 1 resistor.
From the project
The only purpose of this is to provide a nice end to the chain. It has rounded corners like the PSU at the beginning, and it also has a 120ohm termination resistor for the RS485 bus. You can skip using an end cap if you hand solder a termination resistor and tape up the driver ed

You can skip using an end cap if you hand solder a termination resistor and tape up the driver edge connectors to prevent shorts.
