Heltec IOT LORA Turtle Board 915MHZ STM32 LoRa L432 SX1276 lora Development Board LoRaWAN and RadioShuttle

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. Turtle Board is a highly integrated, fully functional board (part of the ``Heltec LoRa`` series) with the following features: CE Certificate; Microprocessor: STM32L432KC (32-bit ultra-low power MCU) with LoRa node chip SX1276; Micro USB interface with complete protection measures such as voltage regulation, ESD protection, and short circuit protection; Onboard AAA x 2 battery holder, USB / battery power automatically switch; Reserve IPEX and SMA antenna interfaces for LoRa use; Programming and debugging interface can be combined with our downloaderSupport DFU protocol, which can be downloaded conveniently via USB (combined with “RadioShuttle STM32 Utility”)Professional software support (ARM Mbed IDE); Provide Standard LoRaWAN protocol routines;Good RF circuit design and perfect low-power design (sleep current: 4uA), which is convenient for IoT application vendors to quickly verify solutions and deploy applications;
