Boards in 2 GitHub repositories, designed in KiCad, that use the STC3115AIQT by STMicroelectronics (-40℃~+85℃ 2.7V~4.5V 2uA I2C Monitoring IC DFN-10(2x3) Battery Management ROHS). See how each wires it, with its parts, size, README and files; the STC3115AIQT’s symbol, footprint and pinout are on its own page.
