A daisy chainable battery monitor
This is a battery monitor meant to monitor lead acid batteries. If the battery voltage goes below a configurable set point, set by the potentiometer, the LED will turn on, and the optocoupler will pull the output line on the TRS connectors low.
To use the signal, supply 5v and gnd on the tip and sleeve of a 3.5mm mini-jack cable, and solder the jumper on one of the PCBs. Then just chain them together. If the battery voltage goes low on any of the batteries, the signal line will go low.

Questions
How big is the Chainable bat mon PCB?
It measures 38 × 30 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Chainable bat mon use?
20 parts, built around the LM393 and SFH617A-1. 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 Chainable bat mon KiCad files?
From the Duckle29/chainable-bat-mon repository on GitHub, at the commit this page was made from: the board is chainable-batmon.kicad_pcb. PCBKit opens the board in the browser, with nothing to install.
Can I use the Chainable bat mon design in my own project?
Its repository publishes it under the MIT licence: you may reuse it on that licence's terms (keep the author's notice, and for a copyleft licence share your changes alike).
