      如題,我看 cool-pi 版子 pmic IC spec 有 support 到 3.8V-24V 想說如果我今天有三顆 18650 並連起來(3.3v-4.2V) 然後從 typeC usb 灌電進去,整個系統會不會有什麼問題?另外,如果改用串連起來(約 12V )灌電進去會有問題嗎?

        @tonyone0902 最低输入电压5V,所以并联是不行的,串联12V从TYPEC输入没有问题。

          @george 謝謝,請教一下,板上除了typeC供電孔外,有其他焊點或者是pin腳可以直接灌12V電進去嗎?

              @jack_admin @george 請教一下,cool pi 是否有電量偵測的功能?

                @tonyone0902 如下图所示,板子的BOTTOM面有测试点,可以焊接外部电源。

                机器本身不具备电量侦测功能,可以外加库仑计通过I2C接口。
