                    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.


                    The turnkey Turtle board solution can be used immediately. Support standard LoRaWAN protocol and RadioShuttle protocol. The included RadioShuttle radio protocol software enables node-to-node communication without additional routers and servers. The Turtle LoRa board by HelTec Automation can run 10 years on AAA batteries (standard or rechargeable NiMH) using the “RadioShuttle” LoRa wireless low-energy protocol software.
                    About RadioShuttle protocol:
                    RadioShuttle Protocol is a node-to-node LoRa wireless communication protocol software. Compare with LoRaWAN(TM), which is capable of efficiently sending messages in a fast and secure way, any node can work as a gateway. We also provide the MQTT server and IOS / Android APP examples source code.
