README
README.mdCANShunt
An 8-channel current sense board with lever actuated WAGO terminals designed for DIN rail mount and measuring load currents on a 12V system.
What for?
In my camper, I distribute power to a number of different loads -- heater, fridge, lights, etc. I'd like to measure the consumption of each individually.
Features
- INA183 current sense amps with a 20A measurement range
- WAGO screwless terminals which can accomodate AWG 12-24 size wiring
- USB-C for DFU firmware load
- CAN bus for communication (CANOpen)
- LED per channel for indicating current
- Mode button for enabling/disabling flashy LEDs
DIN Rail Mounting
The board is designed to support being mounted on a DIN rail via either the CIME system or via Pheonix Contact 1201578 adapters.
Generating output
Needs InteractiveHtmlBom python package: pip install InteractiveHtmlBom
./generate_outputs.sh <rev> to generate output files.
Errata
Rev 2
- Doesn't exist yet
Rev 1
- VIN protection diodes are backwards.
- Sense resistors have wrong footprint. I used 1206; should be 2512. They can be installed OK anyway.
CAN_Dis on wrong MCU pin. Cut trace / jumpers required to fix.

Questions
How big is the CANShunt PCB?
It measures 110 × 72 mm and has 4 copper layers, 1.6 mm thick.
What parts does the CANShunt use?
124 parts, built around the SN65HVD230D, USBLC6-2SC6, SMAJ24A and CUS10S30,H3F. 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 CANShunt KiCad files?
From the mcbridejc/CANShunt-pcb repository on GitHub, at the commit this page was made from: the board is CANShunt.kicad_pcb and its schematic CANShunt.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the CANShunt design in my own project?
Its repository states no licence, so its author keeps all rights: ask mcbridejc before reusing the design.
