Overview
Current sensor filter is an open-source printed circuit board by Synthron, from the Synthron/ModLab repository on GitHub. It is a 4-layer board of 160 × 100 mm with 95 parts on 67 nets, routed with 434 tracks and 266 vias.
It is built around the LM2904 and BSS138. Its parts include 37 capacitors, 29 resistors, 10 connectors, 7 ICs and 4 inductors. It belongs with the sensors and measurement boards and the STM32 boards of this library.

A modular station for your electronic workbench
The ModLab is designed to be housed in a 19" Rack with 3U.
It is the improved version of the (failed) Arduino Workstation I built a long time ago.
But now It will be bigger, better and way too complicated.

Questions
How big is the Current sensor filter PCB?
It measures 160 × 100 mm and has 4 copper layers, 4.69 mm thick.
What parts does the Current sensor filter use?
95 parts, built around the LM2904 and BSS138. 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 Current sensor filter KiCad files?
From the Synthron/ModLab repository on GitHub, at the commit this page was made from: the board is Hardware/V3/current_sensor_filter/current_sensor_filter.kicad_pcb and its schematic Hardware/V3/Bustermination/Bustermination.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Current sensor filter design in my own project?
Its repository states no licence, so its author keeps all rights: ask Synthron before reusing the design.
