                    ① – Type:
                    Dev-Board – Can be used directly;
                    Module – Only core function, need to cooperate with external PCB or circuit.
                    ② – Lithium: All lithium battery socket for Heltec boards is SH1.25-2;
                    ③ – Vext: 3.3V(500mA) output, for external devices (e.g. sensors) power supply, in deep sleep mode, Vext can be shut down via software;
                    ④ – Low Power: Products’ low power design, of Whole Circuit, the measured data are the current of the system during deep sleep.
