TemperaturePCB/README.mdDIYBMS TEMPERATURE SENSOR BOARD
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.
Look inside the "export" folder for the relevant production files. Support this project by using JLCPCB referral link https://jlcpcb.com/RSZ when registering for the first time.
