This is the hardware for a TEMPERATURE SENSOR BOARD. This works with the all-in-one and v450 modules.
KiCAD 7
This design uses KiCAD version 7.0.5. Use the same or newer version for editing and viewing the files. You don't need to install KiCAD if you just wish to build one.
JLCPCB
This design will create a PCB and design files suitable for "almost" full construction at JLCPCB. Some manual soldering will still be required for the connectors and cabling.

Questions
How big is the ControllerCircuit PCB?
It measures 122.5 × 87.6 mm and has 2 copper layers, 1.6 mm thick.
What parts does the ControllerCircuit use?
113 parts, built around the SN65HVD1050D, LT219-1, AMS1117-3.3 and EL3H7(B)(TA)-G. 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 ControllerCircuit KiCad files?
From the stuartpittaway/diyBMSv4 repository on GitHub, at the commit this page was made from: the board is ControllerCircuit/ControllerCircuit.kicad_pcb and its schematic ControllerCircuit/ControllerCircuit.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the ControllerCircuit design in my own project?
Its repository states no licence, so its author keeps all rights: ask stuartpittaway before reusing the design.
