README
README.mdLi-Po_Monitor
Custom Voltage and Current LiPo monitor PCB with SPI-CAN Circuit, LCD Display and piezo buzzer. Current is measured via through-hole Hall-Effect sensor with an analog output while voltage is measured in each Li-Po cell using an extended ADC IC. This was designed to monitor the Li-Po Batteries used on the Sooner Rover Team and facilitate simple integration into the CAN-Bus.

Questions
How big is the Battery monitor PCB?
It measures 63.5 × 113 mm and has 2 copper layers, 1.6 mm thick.
What parts does the Battery monitor use?
46 parts, built around the MCP3208-BI/P, MAX3051EKA and BZV55B3V3. 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 Battery monitor KiCad files?
From the JackCornette/Li-Po_Monitor repository on GitHub, at the commit this page was made from: the board is battery_monitor.kicad_pcb and its schematic battery_monitor.kicad_sch. PCBKit opens the board in the browser, with nothing to install.
Can I use the Battery monitor design in my own project?
Its repository states no licence, so its author keeps all rights: ask JackCornette before reusing the design.
